Cutaneous T-cell lymphoma presenting with diffuse lymphomatous infiltration of the peripheral nerves: response to combination chemotherapy.

A patient with nonepidermotropic cutaneous T-cell lymphoma presented with severe diffuse peripheral neuropathy that was the result of lymphomatous infiltration of the peripheral nervous system. There was no other evidence of systemic disease. The diagnosis was delayed because of the unusual presentation. A peripheral nerve biopsy was instrumental in establishing the etiology of the neuropathy. The patient achieved complete clinical remission with combination chemotherapy.
