Villous adenomas in the urinary bladder are rare neoplasms whose malignant potential is unclear. A case of a morphologically benign non-invasive mucin producing papillary neoplasm of the urinary bladder associated with cystitis glandularis is presented. Absence of A tissue isoantigen from the neoplastic and metaplastic cells and the presence of H tissue isoantigen in both neoplastic and metaplastic cells is observed in a patient whose blood type is A, indicating incomplete maturation of surface coat constituents. The histologically benign appearance of this lesion may belie a malignant potential.
膀胱绒毛状腺瘤是一种罕见的肿瘤，其恶性潜能尚不清楚。本文报告一例形态学上为良性的非侵袭性膀胱黏液分泌性乳头状肿瘤，伴有腺性膀胱炎。在一名血型为A的患者中，观察到肿瘤细胞和化生细胞中缺乏A组织同种抗原，而肿瘤细胞和化生细胞中均存在H组织同种抗原，这表明表面糖蛋白成分成熟不完全。该病变在组织学上的良性表现可能掩盖了其恶性潜能。
