Mucosal malignant melanomas in the gastrointestinal tract and urogenital organs
The aim of this article is to investigate the latest knowledge of the aetiology, pathogenesis and treatment of mucosal malignant melanomas (MMM) in the gastrointestinal tract (GIT) and urogenital organs. MMM constitute 1.4% of all melanomas with an incidence rate in USA of 2.2 per million a year. MMM in the GIT occur mostly in the anal canal and rectum, but can also occur in the small intestine, gallbladder and the large intestine, though very rarely. Melanomas can occur in almost any part of the urinary tract. The aetiology and pathogenesis are unknown. Surgery appears to be the most effective treatment.
