[Metastatic melanoma of unknown primary site].

Abstract

In our series the frequency of melanomas of unknown primary site is comparable to that observed in other studies. Compared to melanomas of known primary site, there was a preponderance in men and in slightly older patients. There was a majority of single glandular localizations and no particular site was preponderant. Survival of Stage III patients was comparable to that of melanomas of know primary site. However, for stage IV patients it appeared better, as has been noted in other series. Treatment of metastatic melanomas of unknown primary site should therefore be the same as that of classical forms. Whenever possible, surgery remains the first indication. Search for the primary site must be orientated by clinical examination including complete examination of the skin and mucosa (ENT, ophthalmologic and genito-urinary), eventually associated with paraclinical investigations, depending on the symptoms.
