原发性膀胱腺癌是一种少见的膀胱恶性肿瘤。本组报告16例，男性13例，女性3例。粘液组化结果：膀胱腺癌PAS／AB和HID／AB染色显示类似胃肠道腺癌粘液分泌；免疫组化结果：9例Keratin阳性，13例CEA阳性。提示原发性膀胱腺癌发生于移行上皮的腺上皮肠化生。此外，对于膀胱腺癌预后与病理的关系作了简要讨论。
Primary cystadenocarcinoma is a rare bladder malignancy. The group reported 16 cases, 13 males and 3 females. Mucin histochemical results: PAS / AB and HID / AB staining of bladder adenocarcinoma showed mucosal secretion similar to that of gastrointestinal adenocarcinoma. Immunohistochemical results showed that 9 cases were positive for Keratin and 13 cases were positive for CEA. Tip of primary cystadenocarcinoma occurred in transitional epithelial gland epithelial metaplasia. In addition, the relationship between the prognosis of bladder adenocarcinoma and pathology was briefly discussed.
