Rhinopharyngeal B-cell non-hodgkin lymphoma: unusual presentation with massive hematemesis.

Lymphomas are the third most frequent type of childhood cancer after acute leukemias and brain tumors. Symptoms at diagnosis are extremely different depending on several factors such as histological subtype, disease extent, and site of tumor. We report an unusual presentation describing a case of epistaxis of the posterior nasal fossa with severe hematemesis.
