[Characteristic features of the diagnosis and clinical course of malignant rectal melanoma].

The paper discusses the results of an analysis of clinical data on 47 in patients with rectal malignant melanoma. Unsatisfactory results of treatment were largely due to erroneous interpretation of morphological features of pigmented lesions in the rectum, preclinical misdiagnosis and inadequate treatment. Long-term results of the treatment will remain unsatisfactory unless early diagnosis and timely surgical intervention involving abdomino-perineal extirpation (electrosurgery are provided).
