basaloid squamous cell carcinoma pathology outlines

Background: Basaloid squamous cell carcinoma (BSCC), an aggressive tumor of the aerodigestive tract, was described over 20 years ago, and its defining histologic parameters remain largely unchanged. Basaloid squamous cell carcinoma of the head and neck. The histology of basaloid squamous cell carcinoma (BSCC) can resemble that of adenoid cystic carcinoma (AdCC). Weedon’s Skin Pathology (Third edition, 2010). Peripheral palisading and clefting is lost. Immunohistochemistry is typically unhelpful but numerous stains are sited in the literature including Bcl-2, Ber-Ep4 and CD34. Fakhry, C., Westra, W. H., Li, S., Cmelak, A., Ridge, J. Risk factors: Alcohol consumption. DDx: Spindle cell melanoma. Basosquamous carcinoma: While this tumour may also be considered in the differential diagnosis as within the umbrella of squamous cell carcinoma, the clinical and histological features more closely resemble basal cell carcinoma. BSCC occurs most commonly in the esophagus, lungs, and head and neck. Any abnormality found on a Pap smear, is further scrutinized with an instrument, called a colposcope, and a biopsy of the abnormal areas performed, to make a diagnosis. Surgery is performed under general or epidural anesthesia, though the ability to have children is lost. Kwon YS(1), Kim YM, Choi GW, Kim YT, Nam JH. Early stage tumors are treated with radiation therapy, while advanced stages are treated with combination of chemotherapy and radiation therapy (chemoradiation). The radioactive material may be injected into a vein, inhaled, or swallowed. Burning-hot beverages. Basaloid tumors are a common diagnostic problem in salivary gland pathology. Isolated native Merkel cells stain with CK20 in desmoplastic trichoepithelioma but will be absent in microcystic adnexal carcinoma. Topics A–Z Contact us to sponsor a DermNet newsletter. Stage III cervical cancer: The cancer has spread to the lower third of the vagina, and/or onto the pelvic wall, and/or has caused kidney problems. 1.2.1 Tumour extent; 1.3 Uterine cervix; 1.4 Vulva. App to facilitate skin self-examination and early detection. Figure 12. Tangential cuts. This study investigated histopathological variations of BSCCE. Thirty-eight surgical and two endoscopically resected specimens of BSCCE were examined. Classically base of tongue. cell carcinoma and were re-categorized as a subtype of squamous cell carcinoma. The US-based Centers for Disease Control and Prevention (CDC) may be contacted for more information. If you can trace the squamous cells from a gland to the surface i… Basaloid squamous cell carcinoma of the bladder has also been reported with small-cell carcinoma. The colposcope is then used to get a magnified view of the inside, To make the abnormal areas more visible, a weak acetic acid (like vinegar) solution is applied to the cervical surface. Non-squamous penis cancer only ~5% of cases. Abstract: Basaloid squamous cell carcinoma（BSCC）is a rare aggressive malignant tumor that is a distinct vari- ant of squamous cell carcinoma. Typically poor prognosis. Sebaceous differentiation: Basal cell carcinoma can also occasionally show areas of significant sebaceous differentiation (figure 12). 1 Sites. • Three patients with tumors exhibiting features of a BSCC are reported. Squamous cell carcinoma (SCC) accounts for about 20% of all lung cancers. The overall incidence of basaloid carcinoma was 4.8%. However, delineating each of these tumor types is facilitated by an algorithmic approach incorporated by … By definition, SCC shows keratinization and/or intercellular bridges. Basaloid squamous cell carcinoma of cervix showing neuroendocrine differentiation. A solution of Lugol’s iodine may also be used for this purpose, The procedure is usually not performed, when a woman has menstrual bleeds, It is generally not painful, but in some women it may cause discomfort or cramping, Colposcopic biopsy: The abnormal areas of the cervix are visualized with a colposcope. CK5/6, CK10, CK14 are also expressed. Cartilaginous invasion is unusual (figure 1). Mod Pathol. Am J Dermatopathol. [] A 54-year-old male had multiple sclerosis-related neurogenic bladder and chronic UTIs. Paulino, G., Augusto, F., Singh, B., Shah, J. P., & Huvos, A. G. (2000). Basaloid squamous cell carcinoma (BSCC) is an uncommon variant of squamous cell carcinoma (SCC) that arises in a variety of anatomic sites, including the anus, 1 the thymus, 2 and the uterine cervix. Basaloid squamous cell carcinomas are composed of solid nests (a, hematoxylin-eosin, original magnification350) and strands (b, hematoxylin-eosin, original magnification3100) of basaloid cells. Marks, R. A., Cramer, H. M., & Wu, H. H. (2013). Grading There is no consensus on how grading of lung SCC should be done; however, a three tiered system is suggested in the CAP protocol, [4] and some older data is suggestive that such a system for lung SCC can be predictive. Some risk factors are more important than others. Herein, we report two cases of BSCC with adenoid cystic‐like features (BSCC‐AdC). It may be performed to see if the cancer has metastasized/spread to other regions, Cystoscopy (to look at the inside of the bladder), Proctoscopy (to look at the inside of the rectum), Sometimes, an intravenous pyelogram (to find any abnormality/blockage in the urinary tract) may be conducted, As the cancer progresses, it may invade into the vagina and surrounding tissues, Over time, the lymph nodes and other pelvic organs may be affected, The cancer can also spread to distant organs; distant metastasis is frequent to the lungs, peritoneum (abdominal cavity), liver, and GI tract, Side effects of chemotherapy (such as toxicity) and radiation, Sexual dysfunction can take place as a side effect of surgery, chemotherapy, or radiation therapy, Recurrence of the cancer following incomplete surgical removal, The FIGO (International Federation of Gynecology and Obstetrics) and the AJCC (American Joint Committee on Cancer) TNM staging systems - are two similar, commonly used staging systems, A tumor that remains confined only to the superficial layers of the cervix is said to be carcinoma in situ (Stage 0 according to AJCC system), Depending on how far the tumor has spread beyond the cervix, stages I through IV are defined, Stage I cancer is confined wholly to the cervix (the cancer has spread to involve even the deeper layers of the cervix unlike stage 0), Stage IV cancer involves the nearby organs, such as the bladder, rectum, or even other distant organs, In this stage, abnormal cells are found in the innermost lining of the cervix, These abnormal cells may become cancer and spread into nearby normal tissue, Stage IA: A very small amount of cancer that can only be seen with a microscope is found in the tissues of the cervix, In stage IA1, the cancer is not more than 3 mm deep and not more than 7 mm wide, In stage IA2, the cancer is more than 3 mm, but not more than 5 mm deep; it is not more than 7 mm wide, Stage IB: It is divided into stages IB1 and IB2, based on the size of the tumor, In stage IB1, the cancer can only be seen with a microscope and is more than 5 mm deep and more than 7 mm wide; or the cancer can be seen without a microscope and is not more than 4 cm, In stage IB2, the cancer can be seen without a microscope and is more than 4 cm, Stage IIA: The cancer has spread beyond the cervix to the upper two-thirds of the vagina, but not to tissues around the uterus, Stage IIA is divided into stages IIA1 and IIA2, based on the size of the tumor, In stage IIA1, the tumor can be seen without a microscope and is not more than 4 cm in size, In stage IIA2, the tumor can be seen without a microscope and is more than 4 cm in size, Stage IIB: The cancer has spread beyond the cervix to the tissues around the uterus, but not onto the pelvic wall, Stage IIIA: The cancer has spread to the lower third of the vagina, but not onto the pelvic wall, Stage IIIB: The cancer has spread to the pelvic wall; and/or the tumor has become large enough to block the ureters (the tubes that connect the kidneys to the urinary bladder). Types of cervical biopsies include: Two methods can be used to obtain a cone biopsy specimen: If a diagnosis of cancer is made on biopsy, further imaging (or other) studies may be conducted. BerEP4 is diffusely present in most tumours, while EMA is infrequently positive. Like small cell carcinoma, it is strongly linked to smoking. Background: Basaloid squamous cell carcinoma (BSCC), an aggressive tumor of the aerodigestive tract, was described over 20 years ago, and its defining histologic parameters remain largely unchanged. H&E stain. They are most commonly non-keratinising. The precise distinction between adenocarcinoma and squamous cell carcinoma (SqCC) has become very important for determining the appropriate therapy for patients and more specifically to drive the use of tyrosine kinase inhibitors, pemetrexed, anti-VEGF monoclonal antibody and crizotinib. Extra large nuclei/bizarre nuclei. Porocarcinoma. This is done by making an incision on the abdomen (termed abdominal hysterectomy), or through the vagina (termed vaginal hysterectomy), or by using a laparoscope (termed laparoscopic hysterectomy). Pigmented BCC: Focal deposits of melanin are evident throughout the tumour. Journal of the National Cancer Institute, 100(4), 261-269. Microcystic adnexal carcinoma: This can be difficult to distinguish from infiltrating basal cell carcinoma and desmoplastic trichoepithlioma. Basaloid squamous cell carcinoma (BSCC) is a rare variant of SCC having a marked predilection for the upper aerodigestive tract. Basaloid squamous cell carcinoma of the lung is a very rare subtype of squamous cell car-cinoma. IHC: Typically keratin -ve. It mainly consists of clusters of basal-like cells, which are palisade-arranged around the tumor. With this invasive procedure, the ability to have children is lost. The Laryngoscope, 110(9), 1479-1482. We retrospectively evaluated cases originally diagnosed as basaloid SCC for histologic characterization. This procedure, lasting about 10 minutes, may cause some cramping and mild-to-moderate bleeding, for a few weeks, Cold knife cone biopsy: This procedure is performed, either under general anesthesia or under spinal anesthesia. However, since this variant is an aggressive form of cancer, the prognosis of the tumor is much worse than other histological subtypes, Almost all women diagnosed and treated at Stage 0 for Squamous Cell Carcinoma of Cervix survive for 5 years post-diagnosis (5-year survival rate of 99-100%). Basaloid pattern of squamous cell cancer. TWO COMMERCE SQ, 2001 MARKET ST, PHILADELPHIA, PA 19103 USA: LIPPINCOTT WILLIAMS & WILKINS. 1990 Sep;3(5):599-608. Sebaceoma: This tumour will usually show a more lobulated architecture, and lack palisading, clefting and mucinous stromas. This may take a long period of time, The final step is the development of cancer from the premalignant stage: The time period of development from premalignancy to malignancy is variable, but can be very slow and may take many decades, Pain during and bleeding after intercourse, Urinary bladder pain and blood in urine (hematuria), The tumor may spread from the cervix to the ureters leading to decreased urine production by the kidneys (anuria) and increased blood urea levels (uremia), Involvement of the pelvic muscles by tumor cells can cause pain radiating along the leg, Occasionally, swollen lymph nodes in the groin and lower extremities, may be noted due to tumor metastasis, If the urinary bladder is involved, then it may obstruct the bladder and lead to retention of urine, Urinary retention can cause the abnormal formation of a fistula in the urogenital area (vesicovaginal fistula or even a rectovaginal fistula), Rectal tenesmus or the urge to keep emptying the bowel, even after it is emptied, In order to make a diagnosis of Basaloid Squamous Cell Carcinoma of Cervix, a detailed history followed by a physical and pelvic exam is undertaken, During a pelvic examination, the healthcare provider will exam the uterus, cervix, vagina, ovaries, fallopian tubes, bladder, and rectum to check for any abnormal changes in these organs, Also, during the exam, the tumor may appear as a polyp (exhibiting exophytic growth pattern), or it may appear as a firm, non-polyp area (exhibiting endophytic growth pattern), Small tumors that may arise in the cervical canal area may be difficult to visualize. In addition to tumor recognition, physicians also track the amounts of these chemicals during various stages of treatment as a means of gauging progress. Once, Basaloid Squamous Cell Carcinoma of Cervix has sufficiently progressed and the presence of large-sized tumors is seen, the following set of signs and symptoms may be observed: During the advanced stages of Basaloid Squamous Cell Carcinoma of Cervix, the following signs and symptoms may be observed: Blood tests to aid in the diagnostic process may include: Some of the definitive tests that help in diagnosing the cancer include: Cervical biopsy: Biopsy is the process of removing tissue for examination. Treatment options for Basaloid Squamous Cell Carcinoma of Cervix include: Some steps for the prevention of Basaloid Squamous Cell Carcinoma of Cervix include: The U.S. National Breast and Cervical Cancer Early Detection Program (NBCCEDP) aims to provide screening tests for breast and cervical cancer to women in underserved areas, or those without health insurance, either for free or at a low cost. Basaloid Squamous Cell Carcinoma of the Rectum: A Rare Entity We report a case of a 33-year old woman with a squamous-cell carcinoma of the rectum, of the basaloid subtype, infiltrating the uterus. In INTERNATIONAL JOURNAL OF GYNECOLOGICAL CANCER (Vol. In addition, TP63 is an essential transcription factor to establish squamous cell identity. 1.1 Skin; 1.2 Head and neck. 25, No. The Malaysian journal of pathology, 35(2), 177. CD10, while positive in basal cell carcinomas and trichoepithelioma, tends to show  peritumoral stromal reaction also. If you have any concerns with your skin or its treatment, see a dermatologist for advice. G2 - moderately differentiated - keratinization focal (typically limited to keratin pearls, individual cells … While. It is always important to discuss the effect of risk factors with your healthcare provider. Oral surgery, oral medicine, oral pathology and oral radiology , 120 (3), e169-e173. After numbing the cervix with a local anesthetic, an instrument, called a biopsy forceps, is used to get a tissue sample. OBJECTIVE/HYPOTHESIS: Basaloid squamous cell carcinoma (BSCC), an uncommon tumor with predilection for the upper aerodigestive tract, is a … Lacks infiltrate of immature T cells typical of most thymomas Basaloid squamous cell carcinoma (BSCC) of esophagus (BSCC-E) is a rare malignant neoplasm. Liou, B., & Li, M. C. (2013). Forty-five cases of BSCC and 34 site-matched cases of squamous cell carcinoma (SCC) were obtained from the archives of the pathology department at our institution. Stage II is divided into stages IIA and IIB, based on how far the cancer has spread. This helps the physician get a magnified view of the cervix, In order for this procedure to be performed, the female individual has to lie on a table, as for a pelvic exam. Read more. Even though a wide age range is observed, SCC of Cervix is uncommon below age 30 years, Generally, no specific preference for any race or ethnic group is noted, Infection with human papilloma virus (HPV) types: It is considered to be a significant risk factor for this tumor type, Sexual promiscuity (multiple sexual partners) and high-risk sexual behavior, Poor immune system: HIV infection or AIDS, organ transplantation, immunosuppressant medications, greatly increase risk for chronic infection, Use of oral contraceptives for long time duration, Having the first child at a young age (before 17 years) and having had multiple pregnancies, Presence of other sexually transmitted infections (such as chlamydia), Family history of cervical cancer: This is a relatively ‘low strength’ risk factor, Under normal circumstances, certain genes called tumor suppressor genes, keep a check on the growth and division of cervical cells, HPV infection has been found to disrupt some tumor suppressor genes, thus allowing cervical cells to grow and multiply uncontrollably, The first step is an individual acquiring HPV infection: High-risk individuals are those with multiple sexual partners, or sex with high-risk or highly promiscuous men (more the number of partners, the greater is the risk), The next step is the persistence of HPV infection and formation of premalignant lesions. 3.1 Images; 4 Sign out. Removal of lymph nodes may lead to swelling of legs (lymphedema), Pelvic exenteration: The uterus, tissues surrounding the uterus, cervix, pelvic lymph nodes, and the upper part of the vagina, are removed. Inflammation (lymphocytes, plasma cells). The basaloid variant of Cervical Squamous Cell Carcinoma has a poorer prognosis than other subtypes, Basaloid Squamous Cell Carcinoma of Cervix is a rare subtype that usually occurs in women between the ages of 45 and 55 years (average age 51 years). There are very few data on the morphologic variation within basaloid SCC of the anus, which may contribute to misdiagnosis. Difference in characteristics and outcomes of basaloid squamous cell carcinoma and squamous cell carcinoma, usual type in cervix: A population-based study from SEER 18 database. Hence, a careful exam in a high-risk individual is recommended, A Pap smear, if not performed already, may be ordered as a screening procedure. p63 +ve. A vast majority of cancers arising from the cervix are squamous cell carcinomas. Thirty-eight surgical and two endoscopically resected specimens of BSCCE were examined. Figure 4 It is regarded as a high-grade tumour with increased propensity for metastasis to distant sites. Beer TW, Shepherd P, Theaker JM. Basaloid Squamous Cell Carcinoma of Cervix is a histological variant of Cervical Squamous Cell Carcinoma. Usually a good outcome - 5 year cause specific survival ~ 81%. Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma with a high rate of distant metastasis. Basaloid squamous cell carcinoma of the bladder has also been reported with small-cell carcinoma. Stage IV cervical cancer: In stage IV, the cancer has spread beyond the pelvis, or can be seen in the lining of the bladder and/or rectum, or has spread to other parts of the body. Almost all types of variants are related to human papilloma virus (HPV) infection, Screening with Pap smear helps in early detection of pre-cancers and cancers. Figure 6. Basaloid squamous cell carcinoma (BSCC) is an uncommon variant of squamous cell carcinoma (SCC) that arises in a variety of anatomic sites, including the anus, 1 the thymus, 2 and the uterine cervix. This blockage can cause the kidney to enlarge or stop working, Stage IVA: The cancer has spread to the nearby organs, such as the urinary bladder or rectum, Stage IVB: The cancer has spread to other parts of the body, such as to the lymph nodes, lung, liver, intestine, or bone, Stage 0 tumors, confined to the superficial layers of cervix can be treated with cryosurgery (the cells are killed using extreme cold temperatures) or by using laser therapy, Conization procedure, besides helping with the biopsy, can also help in treating very early-stage Cervical Cancers in women, who want to preserve their childbearing ability, Radical trachelectomy: The surgeon removes the cervix, upper part of the vagina, and nearby lymph nodes, while preserving the ability to have children, Hysterectomy: In this procedure, the uterus and cervix are removed. Basaloid squamous cell carcinoma. » Immunostaining may be helpful with sebaceoma rarely positive for BerEP4, while typically positive with EMA. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis.
