A Rare Differential Diagnosis of an Adrenal Mass: A Case Report

Abstract

Ten years after his last treatment for diffuse large B-cell lymphoma, a seemingly healthy, 64-year-old man presented for his lymphoma-related follow-up. Ultrasound revealed an impressive tumor in the right adrenal gland. Due to recurrent cancer therapies in the past, this seemed highly suspicious of a second malignancy, such as primary adrenal carcinoma. Surprisingly, histology disclosed a very different but rare cause for this pseudotumorous lesion.
