m e l a n o m a of the anus and rectum has been well established. A p p r o x i m a t e l y 180 cases have been r e p o r t e d since the first description of its occurrence in man by Moore in 1857.16 Of these, 16 cases have involved the rectal a m p u l l a or rectosigmoid colon without evidence of a melanotic lesion of the anus or anal canal ( T a b l e 1)Y T h e 16 patients were 11 men and five women. T i l e lesion was most often discovered when the patients were between 50 and 65 years of age. Five patients were less than 50 years old. Distances of the lesion from the anus ranged from 3 to 15 cm. A l t h o u g h the m e a s u r e m e n t in each case might be questioned for accuracy, there is no d o u b t that none of the lesions involved the a n o d e r m or anal canal. T h i s p a p e r has been p r e p a r e d to document the seventeenth known p r i m a r y occurrence of a m a l i g n a n t m e l a n o m a above the anal canal.
