Abstract


RÉSUMÉ
Les mélanomes primitifs des muqueuses de la tête et du cou sont des entités pathologiques rares. Ils surviennent volontiers chez l’homme entre la 5e et 8e décade. Le diagnostic est souvent tardif. Le type lentigineux est le plus rencontré dans ces localisations muqueuses des mélanomes. La grande diversité des formes histopathologiques observées et décrites leur confère très souvent un caractère de mauvais pronostic. Pronostic encore plus péjoratif lorsque la tumeur se développe sur un site anatomique inaccessible à la vue. Les auteurs rapportent le cas d’un mélanome nodulaire du palais chez une dame de 68 ans.


ABSTRACT
Primary melanomas of head and neck mucosa are rare entities. They often occur in men between the 5th and the 8th decade. The diagnosis is usually late. The lentiginous type is the most encountered in these mucosal locations of melanomas. The great diversity of the histopathological forms observed and described very often gives them a character of poor prognosis. Even more pejorative prognosis when the tumor grows on an anatomical site inaccessible to sight. The authors report the case of a nodular melanoma of the palate in a 68 years-old woman.
