Abstract:
Objective: Signet-ring cell carcinoma is a relatively rare cancer which occurs principally in the stomach,colon-rectum,bladder and breast,but seldom in other parts.This article analyzes the clinical and pathologic features of 3 extremely rare cases of primary signet-ring cell carcinoma in the uterus.Methods: Three cases of primary signet-ring cell carcinoma in the uterus were observed by HE and immunohistochemical staining,their clinical features analyzed and the relevant literature reviewed.Results: Of the 3 cases,2 presented nodose tumors in the cervix while the other in the uterine cavity.Histologically,there was a diffuse infiltration of the tumor cells,with an appearance of signet-ring cells.Periodic acid-Sciff(PAS) staining revealed PAS-positive diastase resistant introcytoplasmic material.Immunohistochemically,the tumor cells were positive for CK and CEA.Conclusion: Primary signet-ring cell carcinoma of the uterus is extremely rare.It is always necessary to rule out a metastatic neoplasm by clinical examination and to differentiate it from other tumors/lesions with signet-ring cell features.
