Mésothéliome desmoplastique pleural avec métastases vertébrales. À propos d'un cas

Desmoplastic mesothelioma is unusual variant of malignant mesothelioma. The diagnosis of desmoplastic mesothelioma represents one of the most difficult exercises in pleural pathology (with poor interobservers agreement) because of their abundant collagen with relatively low cellularity. The clinical course is often rapid with visceral metastases. Bony metastases have only rarely been noted. We report our case of desmoplastic mesothelioma with vertebral metastases. Our focus is to distinguish this entity from fibrous pleurisy and localized fibrous tumors, to explain histological and immunohistochemical features with review of the literature.
