title: An unusual case of primary extranodal non-Hodgkin's lymphoma in the muscles of facial expression.
abstract: Primary extra-nodal non-Hodgkin's lymphoma (NHL) of the skeletal muscles is a well recognized entity although such occurrences are not very common. Presentation in the muscles of the face has only rarely been described. We present a case of primary extra-nodal NHL in a non-immunocompromised patient involving only the muscles of facial expression and not extending to the oral cavity or sinonasal tract. The patient was subsequently treated with chemotherapy and at the time of writing remained in remission. We suggest that lymphoma should be considered among the causes for malignant infiltration of the muscles of the face.
