Placental S100 (S100P) and GATA3: markers for transitional epithelium and urothelial carcinoma discovered by complementary DNA microarray. tricholemmal carcinoma (both lacking pre-existing tricho-lemmoma or CD34 staining).9 In 2004 Diaz-Cascajo described a series (n ¼ 16) of follicular squamous cell carcinoma (fSCC) that arose predominantly in the sun-exposed, hair bearing skin of the elderly with a preference for males and behaved indolently.13 Tumours were centred on The relationship between the histological grading of malignancy and the expression of vimentin and cytokeratin was studied in 43 cases of oral squamous cell carcinoma. Squamous cell carcinoma is the most common malignant tumor of the uterine cervix with a well-documented link to infection with human papillomaviruses (HPV). The correct immunohistochemical finding for this tumor is speckled nuclear positivity for NUT1, a sensitive and specific marker of this tumor type. Clinical: yellow-brown scaly, patches, sandpaper sensation. Prevention and treatment information (HHS). Numerous beeds/blobs of epithelial cells that seem unlikely to be rete ridges. We welcome suggestions or questions about using the website. We evaluated the utility of an immunohistochemical panel of 3 urothelial-associated antibodies (uroplakin III, S100P, and GATA3) and two squamous-associated antibodies (CK14 and desmoglein-3) in 50 primary urothelial neoplasms: 15 pure urothelial carcinomas, 12 pure squamous cell carcinomas and 23 urothelial carcinomas with squamous differentiation. Solitary renal metastasis of esophageal squamous cell carcinoma mimicking primary renal neoplasm - A case report and literature review.

According to a recent classification, there are several morphological variants of cervical squamous carcinoma, without reference to sarcomatoid squamous cell carcinoma, which is well described in other organs. © Copyright PathologyOutlines.com, Inc. Click, Female Pelvic Med Reconstr Surg 2014;20:295, Primary squamous cell carcinoma arising in vagina without involvement of surrounding structures, such as cervix or vulva, Comprises 1 - 3% of all gynecological cancers (, 80 - 90% of primary vaginal cancers are squamous cell carcinomas (, Usually in 6th decade of life (median age 58 to 68) but can also be seen in younger patients (, Tumor may be missed on initial examination if small and involves lower 2/3 of vagina (, In some cases, vaginal intraepithelial neoplasia (VAIN) can be found prior to invasive squamous cell carcinoma, History of prior hysterectomy in up to 50% of cases, Also associated with vaginal or uterovaginal prolapse Is there really a difference in survival of women with squamous cell carcinoma, adenocarcinoma, and adenosquamous cell carcinoma of the cervix? ; Apocrine/eccrine carcinomas – These may sometimes show clear cell differentiation. Vascular invasion was observed in all squamous and spindle cell types and in 66% of MCC: estrogen and progesterone receptors were absent in 90% of the tumors. SCC typically shows a more infiltrative invasive front. 1.1. Unsuspected Malignancy During Percutaneous Nephrolithotomy: The Snake in the Grass. Am J Surg Pathol. Features: 1. In US, 90% of bladder tumors are urothelial carcinoma, 5% are pure squamous cell carcinoma or adenocarcinoma #4 most common cancer in US males, #8 in US females In US, there were 64,000 cases and 13,000 deaths in 2006 (all types, invasive and noninvasive, National Institutes of Health) Patient characteristics resemble bronchogenic carcinoma: M > F, cigarette users, urban, age … The present study was aimed to evaluate a reliable diagnostic method for these cancers based on immunohistochemistry (IHC). Results: The best markers to distinguish poorly differentiated metastatic urothelial carcinoma from primary pulmonary squamous cell carcinoma were CK7, CK20, GATA-3, CK14, desmoglein-3, and uroplakin III, with the utility of the latter dependent upon the quantity of tissue available for analysis. (, Strong relationship with high risk human papilloma virus (HPV), especially HPV 16 (seen in up to 80% of cases), HPV 18 and HPV 31, More common in smokers because smoking increases the risk of high grade VAIN in women with oncogenic HPV (, Most common symptom is vaginal bleeding or discharge (, Other symptoms include urinary symptoms and lower abdominal pain (, May remain asymptomatic, especially if small, Clinical history along with histological features on biopsy / resection specimen, Tumor involving both the vagina and the cervix should be classified as a cervical carcinoma; similarly a tumor involving both the vagina and the vulva should be considered a vulvar carcinoma, Imaging required to determine extent of disease and to look for distant metastasis, FIGO stage is most important predictor of overall survival, Tumor size > 4 cm associated with decreased local control and lower overall survival, while total radiation dose in excess of 70 Gy is associated with improved local control of disease and improved overall survival (, Vaginal squamous cell carcinoma can spread to vulva, cervix, bladder, rectum and through lymphatics can metastasize to obturator, hypogastric, external iliac and groin nodes, Rarely distant metastasis to liver, lungs, bones and brain (, 28 year old woman with invasive squamous cell carcinoma of vagina during pregnancy (, 39 year old woman with primary vaginal squamous cell carcinoma arising in a squamous inclusion cyst (, 57 year old woman with synchronous papillary cystadenocarcinoma of ovary and squamous cell carcinoma of lower vagina (, 59 year old woman with vaginal cancer and complicated prolapse history (, 68 year old woman with vaginal cancer and multiple liver and pulmonary metastases (, 84 year old woman with carcinoma of vagina in uterovaginal prolapse (, Aggressive primary invasive vaginal carcinoma associated with HPV 61 (, Various treatment modalities are used including external beam radiation therapy / EBRT, interstitial brachytherapy, intracavitary brachytherapy, chemotherapy and surgical resection, Mainstay of treatment is typically definitive radiation therapy with external beam radiation or brachytherapy (, Surgical resection is recommended for early stage cancer involving upper posterior vagina (, For stage I disease, surgery consists of radical hysterectomy, upper vaginectomy and pelvic lymphadenectomy (, Cisplatin based chemotherapy can be administered with radiation therapy (, Histologically graded as well differentiated (G1), moderately differentiated (G2), poorly differentiated or undifferentiated (G3) (, Well differentiated tumors have polygonal squamous cells with ample eosinophilic cytoplasm, abundant keratin pearls and intercellular bridges, Poorly differentiated tumors have small cells with scant cytoplasm and hyperchromatic nuclei, Nuclear pleomorphism and mitotic activity increases from well to poorly differentiated, Moderately differentiated tumors have histological features intermediate between well and poorly differentiated, HPV+ tumors are more frequently of nonkeratinizing, basaloid or warty type than HPV- tumors (84% versus 14.3%; p < 0.001) and more often showed diffuse p16 immunoreactivity (96% versus 14.3%, p < 0.001), Keratinizing squamous cell carcinomas have polygonal cells with bizarre shapes including spindle shaped and tadpole cells, with dense orangeophilic / eosinophilic cytoplasm, Cells can present singly or in small groups in a dirty necrotic background, Nonkeratinizing SCC needs to be differentiated from. Urothelial neoplasms with squamous morphology raise the differential diagnosis between pure primary squamous cell carcinoma, urothelial carcinoma with squamous differentiation and secondary involvement by squamous cell carcinoma, for example, from uterine cervix. These people sign this entity as low grade squamous cell carcinoma, keratoacanthoma type. Pathology and genetics of tumours of the digestive system. Human papillomavirus-positive oropharyngeal cancer (HPV-positive OPC or HPV+OPC), is a cancer (squamous cell carcinoma) of the throat caused by the human papillomavirus type 16 virus (HPV16).
