title: Malignant melanoma at unusual sites.
abstract: The author deals with natural history an clinical appearance of malignant melanomas occurring at unusual sites. Diagnostic problems, treatment and prognosis are discussed on base of pertinent literary data and own experiences described in case reports of the related clientel (1 case with primary melanoma of the breast region; 1 case with melanoma of the tongue; 4 anorectal melanomas; 1 case with a neurotropic melanoma). Finally, the neurotropic variant of malignant melanoma is described, not for its unusual location but rather for its special histological picture and differential-diagnostic importance.
