| Popis: |
A 56-year-old woman with complaints of anal bleeding and pain visited our hospital, and an elastic soft mass was detected in the anal canal on digital examination.Colonoscopy showed a black Isp polypoid lesion with a black pit from the anal canal to the lower rectum(P-Rb).She was diagnosed with malignant melanoma based on colonoscopic biopsy.Tumor marker levels(CEA, CA19-9)were not increased.No distant metastasis was detected on abdominal CT.No direct invasion was detected on MRI of the pelvis.The patient underwent laparoscopic abdominoperineal resection and D2 lymph node dissection. Histopathology showed a malignant melanoma(pT4b, N0, M0, pStageⅡC).The patient received interferon therapy as adjuvant therapy.There is no sign of recurrence 2 years and 1 month after the surgery.Anorectal malignant melanoma is relatively rare, so establishment of therapy by the accumulation of cases is desired. |
