Taken together, the biopsy findings were consistent with a malignant lymphoma of the large-cell type with B-cell phenotype, associated with numerous reactive T cells and extensive necrosis, so-called lymphomatoid granulomatosis.

The patient was treated with 6 cycles of CHOP (cyclophosphamide, doxorubicin hydrochloride [hydroxydaunomycin (Adriamycin)], vincristine sulfate [Oncovin], and prednisone) during a 5-month period. The fever and arthralgias resolved.
