A 70-year-old female who complained of anal pain and rectal bleeding was told that she had an anal tumor by a local physician and was referred to our hospital. Endoscopy revealed a tumor located above the dentate line on the right upper side. Abdominoperineal resection and wedge resection of the posterior wall of the vagina were performed. The tumor was expophytic, growing between the internal and external sphincter muscle, and histologically diagnosed as mucinous carcinoma originating from anal gland. The carcinoma was 27×15×18 mm in size, and a₁n₀H₀P₀M (-) stage II. Inguinal lymph node dissection was performed 5 months later because of metastasis to the right inguinal lymph nodes. Mucinous carcinoma of an anal gland is rare, and distant metastasis including inguinal lymph node metastasis and local recurrence is likely to occur. The initial symptoms of this lesion are so similar to those of perianal benign disease, such as hemorrhoids, that accurate diagnosis in the early stage is very important.
