Extranodal non-Hodgkin's lymphoma in the malar region - a case report

摘要

The incidence of extranodal non-Hodgkin's lymphomas (NHL) in Asian subcontinent is very low. Extranodal NHL in the malar region are uncommon, and the incidence of these lesions in such site is unknown. Here is a case of slowly enlarging mass from the soft tissue over the right malar region, radiographically appeared to have involved maxillary sinus and histopathologically diagnosed as round cell tumour. Immunohistochemistry analysis was suggestive of diffused large B-cell lymphoma. Definitive diagnosis by immunohistochemistry is a must for accurate diagnosis, treatment and better outcome for such lesions.
