Relapse of Primary Testicular Non-hodgkin's Lymphoma in the Mandible – a Case Report

Metastasis of primary tumors to the jaws from distant sites of the body is rare. In the majority of cases, the primary malignancy is already known at the time of admission while the occult primary may be detected only later. Cellular malignancies especially those of haematopoetic origin, diagnosed in the oral and maxillofacial region are usually found to be secondaries from various locations in the body. However non-Hodgkin's lymphoma (NHL) appearing in the mandible subsequent to a primary tumour elsewhere in the body is scantily reported in the literature. We report a case of relapse of previously diagnosed testicular non-Hodgkin's lymphoma in the mandible. The patient had undergone treatment for primary testicular non-Hodgkin's lymphoma in the left testis one year ago. He remained symptom-free until the appearance of a tumour in the mandible. It is to be noted that there was no sign of metastasis elsewhere in the body other than the present lesion.
