Abstract


RÉSUMÉ
La tumeur trichilemmale proliférante maligne du cuir chevelu est une lésion cutanée qui se produit habituellement chez la femme âgée. Elle se caractérise par une prolifération épithéliale extensive, une architecture infiltrante, des atypies cytonucléaires marquées et de mitoses nombreuses. Les auteurs rapportent un cas chez une femme âgée de 47 ans. Le diagnostic est anatomie-cytologie pathologique. Le traitement est chirurgical consistant en une exérèse complète de la tumeur suivie d’une chirurgicale plastique de reconstruction du cuir chevelu et complétée par une chimiothérapie. Les habitudes socio-culturelles et à la sous-médicalisation pourrait expliquer la mortalité élevée des formes malignes.
ABSTRACT
Malignant proliferating trichilemma tumor of the scalp is a skin lesion that usually occurs on the elderly women scalp. It is characterized by an extensive epithelial proliferation, an infiltrating architecture, marked cytonuclear atypia and numerous mitoses. The authors report a case in a 47-year-old woman. The diagnosis is pathological anatomy-cytology. The treatment is surgical consisting of a complete excision of the tumor followed by a plastic surgical reconstruction of the scalp and supplemented by chemotherapy. Socio-cultural habits and under-medicalization could explain the high mortality of malignant forms.
