title: [A Case of Malignant Anorectal Melanoma with Laparoscopic Abdominoperineal Resection].
abstract: A 69-year-old man with anemia underwent colonoscopy. Colonoscopy showed a black tumor, 2 cm from the anal verge. The biopsy specimen revealed malignant melanoma, which was preoperatively diagnosed as T1(SM), N0, M0, Stage I . We performed laparoscopic abdominoperineal resection. The tissue type and diagnosis were malignant melanoma, pT1b(10 mm), pN0, pM0, ly0, v0, pDM0, pPM0, pRM0, pStage I b, according to the Colon Cancer Handling Terms, 8th edition). The patient did not receive adjuvant chemotherapy. However, he survived postoperatively for 9 months, with no sign of recurrence.
