 We report a case of a patient who underwent laparoscopy-assisted abdominoperineal resection of the rectum for the treatment of anorectal malignant melanoma. A 67-year-old woman presented at another institution complaining of anal bleeding. On rectal endoscopy, a blackish mass was found, so the patient was admitted to our hospital for detailed examinations. A biopsy specimen was histologically and immunohistologically diagnosed as being anorectal malignant melanoma ; therefore, the patient underwent laparoscopy-assisted abdominoperineal resection of the rectum. Histologically, the tumor was classified as mp, ly 1, v 1, n (-), stage I, and CurA. After surgery, the patient received adjuvant chemotherapy, and at the time of writing she had survived for 1 year after the operation without any sign of recurrence. The prognosis of anorectal malignant melanoma is generally very poor. The surgical approach described here has benefits with respect to the patient's quality of life, and therefore should be considered when deciding on therapy.
