[Effective combined modality therapy for a patient with primary adrenal lymphoma]

Primary adrenal lymphoma is a rare lymphoma with clinical features consisting of a high incidence of bilateral adrenal involvement, diffuse large B-cell histology and secondary adrenal insufficiency. We report a successful treatment of a patient with primary adrenal lymphoma using a combined modality therapy (CMT). A 62-year-old man was hospitalized with pain of the flank, and a computed tomography (CT) scan of the abdomen revealed very large, bilateral adrenal masses. A needle biopsy of the left adrenal mass revealed diffuse large B-cell lymphoma. After irradiation of both adrenal lymphomas and CHOP therapy accompanied by intrathecal treatment and rituximab, the patient underwent a left adrenalectomy and high-dose chemotherapy with autologous peripheral blood stem cell transplantation. The patient has been disease-free for 2 years after the diagnosis of primary adrenal lymphoma. In contrast to the previous reports of poor response to conventional-dose chemotherapy alone and short-term survival of patients with primary adrenal lymphoma, our patient has demonstrated that radiation therapy combined with chemotherapy and rituximab may be an effective modality as a first-line therapeutic regimen for localized primary adrenal lymphoma.
