Inactivates bioactive peptides
Uses:
Breast: marker of myoepithelial cells, Mod Path 2002;15:397
Burkitt lymphoma: confirm diagnosis
Colonic carcinogenesis: increase in stromal cells from mild to severe dysplasia to invasive carcinoma, Hum Path 2002;33:806-8
Endometriosis: helpful in identifying areas of endometriosis if sparse glandular tissue
Follicular lymphoma: to confirm diagnosis
Hepatocellular carcinoma vs. nonhepatocellular carcinomas: 68% sensitive and >95% specific with canalicular pattern, AJSP 2001;25:1297, AJSP 2002;26:978, although another study recommends Hepatocyte, MOC31, and pCEA but not CD10, Mod Path 2002;15:1279
Microvillous inclusion disease: strong CD10+ cylasmic staining vs. linear brush border staining in normals, AJSP 2002;26:902
Positive staining (normal): adrenal cortex, pre-B cells, brain, choroid plexus, cortical thymocytes, endometrial stroma, follicular center cells, granulocytes, kidney microvilli, liver, lymphohemaoietic precursors, male GU epithelium, mesonephric remnants, myoepithelial cells (breast), neutrophils, ovary, placenta (cytotrophoblast, intermediate trophoblast, syncytiotrophoblast), small intestine (linear brush border staining)
Negative staining: myeloid and erythroid precursors, other female genital tract tumors (including clear cell carcinomas)
Micro images: follicular center cells (figure 1), intranodal heteroic mammary ducts (figure 1C),
Micro images (AJSP subscribers): endometrial stromal tumor #1 (negative), #2, hepatocellular carcinoma#1, #2, mesonephric carcinoma of uterus, mesonephric derivatives in men, microvillous inclusion disease#1, #2 (controls), vulvar, vaginal and cervical lesions, uterus and trophoblast, fallopian tube and ovary
Micro images (Hum Path subscribers): canalicular pattern in hepatocellular carcinoma (figure C), gastric carcinoma at apical border (figure B), colonic adenoma, colonic carcinoma#1, #2
Micro images (Mod Path subscribers): canalicular pattern in hepatocellular carcinoma (figure B), malignant mixed mullerian tumor#1, #2, #3, breast myoepithelium, breast adenosis, breast DCIS, invasive ductal carcinoma of breast, diffuse large B cell lymphoma, adenomyosis
