title: [Anorectal melanoma].
abstract: This paper reviews the general concepts (pathological, therapeutic and prognostic) of melanoma in the light of recent data. Unlike cutaneous melanoma which is usually diagnosed early, ano-rectal melanoma is diagnosed late in its course, which results in a very poor prognosis. This delay in the diagnosis is also probably responsible for the failure of surgery.
