-Solitary bone plasmacytoma of the mandible: a case report and review of literature. Introduction:A solitary plasmacytoma is a malignant tumor characterized by proliferation of monoclonal plasma cells. It preferentially reaches the axial skeleton, in particular the rachis and pelvis. Its location in the jaw is exceptional. Observation: A 49-year-old male patient consulted for a right mandibular tumor which had evolved for six months in an asymptomatic way. After surgical excision performed under general anesthesia in order to establish a diagnosis, histological examination showed that it was a plasmacytoma. The extension work-up confirmed the diagnosis of solitary bone plasmacytoma of the mandible. The patient received adjuvant external radiotherapy. The outcome was favorable. Discussion: From this clinical observation and the review of the literature, the clinical aspect, radiological signs, therapeutic solutions and outcome of this rare disease are discussed. Mandibular location of bone plasmacytoma is very rare and diagnosis is first histological.
MOTS-CLEFS : Lymphome, non hodgkinien, sinus maxillaires KEYWORDS: Lymphoma, non hodgkin, maxillary sinusLes lymphomes non hodgkiniens (LNH) sont des tumeurs rares des maxillaires. Leurs localisations aux cavités aériennes de la face arrivent en second rang.Nous rapportons le cas d'un LNH primitif localisé au sinus maxillaire chez un patient de 47 ans, qui illustre les difficultés diagnostiques rencontrées face à une symptomatologie peu évocatrice.Le diagnostic fut confirmé par l'examen histologique. L'évolution fut favorable après un traitement médical à base de chimiothérapie polyvalente associée à une radiothérapie externe.À partir de cette observation, nous ferons une revue de la littérature pour faire le point sur les aspects cliniques, radiologiques, histologiques, thérapeutiques et évolutifs de cette affection rare. Non-hodgkin lymphoma (NHL) are rare tumors of the jaws. their locations in the air spaces of the face coming in second row.We
