Two cases of primary adenocarcinoma of the female urethra are reported. Case 1 was a 75-year-old female presenting with the complaint of genital bleeding. Physical examination revealed a pea-sized tumor in the urethral meatus. Tumor resection was performed under the preoperative diagnosis of caruncles, but, histopathological examination revealed adenocarcinoma. She was readmitted because of recurrence of tumor 7 months after the first operation. En bloc resection including the bladder, urethra and uterus was done followed by ileal conduit for urinary diversion. Case 2 was an 85-year-old female presenting with the complaint of macroscopic hematuria. Physical examination revealed a thumb's-head-sized tumor in the urethral meatus and also the left enlarged inguinal lymph nodes. Tumor resection and biopsy of the left inguinal lymph nodes were performed. Histopathological examination revealed adenocarcinoma. Postoperative irradiation to the left inguinal lymph nodes was given to a total dose of 4,000 rads. Ninety-two cases of primary adenocarcinoma of the female urethra in the Japanese literature including our cases are reviewed.
