Coexistent B-cell lymphoma and cutaneous T-cell lymphoma.

A 78-year-old man with a history of mycosis fungoides was referred for evaluation of a right adrenal mass. A physical examination showed the left cervical lymph node to be palpable, which was later shown to be caused by a diffuse large B-cell lymphoma. The patient was diagnosed with concurrent mycosis fungoides and a diffuse large B-cell lymphoma. Three courses of chemotherapy were performed, however, the patient died of advanced disease. Autopsy findings showed that the right adrenal and soft tissue masses had an identical B-cell origin. Although the exact mechanism remains unclear, the pathogenesis of this rare association is discussed.
