Female urethral adenocarcinoma with a heterogeneous phenotype: Case report
Abstract:Kuroda N, Shiotsu T, Ohara M, Hirouchi T, Mizuno K, Miyazaki E. Female urethral adenocarcinoma with a heterogeneous phenotype. APMIS 2006;114:314–8.
We here report a very rare case of female urethral adenocarcinoma. A 77-year-old woman presented with urinary retention. Cystoscopy showed a urethral tumor and the biopsy material showed adenocarcinoma. Macroscopically, the tumor measuring 3.0×3.0×2.4 cm was predominantly observed around the periurethral area on the proximal side. Histologically, patterns of columnar/mucinous adenocarcinoma, clear cell adenocarcinoma and papillary/micropapillary carcinoma were observed, but there was no evidence of a cribriform pattern. Immunohistochemically, neoplastic cells of at least one of three components were positive for CK7 and CK20 or CA125. We suggest that female urethral adenocarcinoma with a histologically and immunohistochemically heterogeneous phenotype may originate from cells within urethral or paraurethral tissue, such as urethritis glandularis or intestinal metaplastic epithelium and Mullerian tissue.
