The vast majority of vaginal submucosal cysts are benign lesions. Primary malignant tumors of the vagina are infrequent and most are mucosal lesions. A case is described in which an unusual neoplasm, anal duct carcinoma, presented clinically as a vaginal lesion. The importance of considering anal neoplasia in the differential diagnosis of cystic vaginal lesions is noted.
绝大多数阴道黏膜下囊肿是良性病变。原发性阴道恶性肿瘤很少见，且大多数是黏膜病变。本文描述了一例罕见肿瘤，肛管癌，临床上表现为阴道病变。文中指出在阴道囊性病变的鉴别诊断中考虑肛门肿瘤的重要性。
