Soft tissue T cell lymphoma of the forearm: a case report

A patient with a soft tissue T cell lymphoma with symptoms of de Quervain's tenosynovitis and a forearm mass in the area of the abductor pollicis longus and extensor pollicis brevis is described. Previously excised soft tissue masses from other locations had presented a diagnostic dilemma in this patient. This report clarifies the histopathology of soft tissue T cell lymphomas of the extremities. After surgical debulking and local radiotherapy, there has been no evidence of recurrence at 1 year.
