Abstract

Adrenal involvement in the course of malignant lymphoma occurs in about 4% of patients, but primary adrenal lymphoma (PAL) is extremely rare. To the best of our knowledge, only one case study reported the combination of PAL with pheochromocytoma. In the current study, we present the second case who was a 63-year-old man admitted to our hospital with hematuria and abdominal discomfort. Ultrasound imaging indicated the presence of a lesion, 5×4×3 cm in size, in the upper pole of his right kidney. Histopathologic study confirmed a collision tumor composed of pheochromocytoma and diffuse large B-cell lymphoma (DLBCL). © 2018, Tehran University of Medical Sciences (TUMS). All rights reserved.
