Primary adrenal lymphoma. Report of an autopsy case.
A rare case of malignant lymphoma of the adrenal gland in a 68-year-old male is reported. Autopsy revealed bilateral and symmetrical adrenal tumors (lt: 54 g, rt: 39 g) and almost complete effacement of both adrenal glands, while no tumors were present in other organs or systemic lymph nodes. Both adrenal tumors histologically presented a picture of diffuse malignant lymphoma of mixed cell type. Microscopic involvement in both lungs, spleen, liver, lymph node, bone marrow and both kidneys was found. Immunohistochemically, the positive reactions shown by the lymphoma cells were of B cell type, i.e., observed using antibodies to the leukocyte common antigens, MB-1, LN-1, LN-2 and LN-3, but not by anti-factor VIII-related antigen or MT-1. Examination of peripheral blood obtained just before the patient died showed the presence of 18% atypical cells. This lymphoma was considered to have transformed to a leukemic phase, at least at the end stage. To the author's knowledge, this is the second case of primary adrenal lymphoma to be reported in Japan, and the first case showing formation of bilateral and symmetrical tumors.
