Methods:The expression of ER,CEA,vimentin and c erbB 2 in 17 cases of endometrial carcinoma including 5 cases of endometrial mucinous carcinoma(EMC) and 12 cases of ordinary pattern of endometrial carcinoma(OPEC) were studied immunohistochemically(S P method) and compared with that in 5 cases of cervical mucinous carinoma(CMC).
Results: Among 31 cases that 11 cases of adenocarcinoma,4 cases of leiomyosarcoma,3 cases of mucous carcinoma,2 cases of carcinoid,2 cases of lymphoma, 1 cases of undifferentiated carcinoma,and 8 cases of benign tumor were diagnosed pathologically.
Methods:The subject were 84 patients with 93 breast lesions confirmed by pathology, including invasive ductal carcinoma(n=57),mucous carcinoma(n=4),fibroadenoma(n=13),intraductal papilloma(n=4) and other benign lesions(n=15).
Results: Expression of ER was found in 38% (35/91) of gastric carcinoma. The frequency of ER positivity in well-differentiated(10%, 3/30) was significantly lower than that in pooly-differentiated(43%, 13/30), undifferentiated(53%,8/15), mucoid carcinoma (63%, 5/8) and signet ring cell carcinoma (75%, 6/8)(P<0.05).
ER positivity was 10%(3/30) in well-differentiated gastric carcinoma,which was significantly lower than 43%(13/30) in the poorly-differentiated,53%(8/15) in the undifferentiated,63%(5/8) of mucoid carcinoma and 75%(6/8) of signet ring cell carcinoma,respectively(P<0.05).
Results Expressioin of ER was found in 38%(35/91)of gastric carcinoma. The frequency of ER gene positivity in well-diffentiated(43%),undifferentiated(53%),mucoid carcinoma(63%) and signet ring cell carcinoma(75%)(P<0.05).
In order to find out if there is diagnostic significance in differentiating mammary carcinoma from other benign breast lesions by examining for secreting mucinous characters three tests using Periodic acid schiff (PAS),Alcian bulue AB),High iron diamine (HID) were used to stain the mucin. Altogether 11 mammary fibroadenomas,11 dysplastic lesions,10 intraductal papillomas,11 infiltratedductal carcinomas and 11 mucinous carcinomas were subjected to observation.
Objective To discriminate if the mucinous carcinomas are primary to the ovary,stomach or metastases from ovary and stomach by monoclonal antibodies cytokeratin 7,carcinoembryonic antigen,and cytokeratin 20.Methods Immunohistochemical methods were used with these monoclonal antibodies and S P kit.
LOI of IGF2 appears to be associated with a human colorectal cancer phenotype involving younger age at diagnosis, more advanced disease, right-side colonic location, and poorly differentiated or mucinous carcinoma.
Isolated Splenic Metastasis from Colorectal Mucinous Carcinoma
We report a case of isolated splenic metastasis in a 52-year-old man, occurring 9?years after the primary colorectal mucinous carcinoma was treated by anterior resection.
In two patients with Crohn's disease of long duration after more than 17 and 12 years respectively a mucinous adenocarcinoma of the ascending colon and a perianal mucinous carcinoma deriving from the anal ducts developed.
Invasive mucinous carcinoma of the breast missed by contrast-enhanced MR imaging of the breast
