ACTA ENDOCRINOLOGICA (BUC)

Primary bilateral adrenal lymphoma is a very rare cause of adrenal insufficiency. We report the case of a 63-year-old woman who presented with signs and symptoms of impending adrenal crisis when referred for evaluation of large bilateral adrenal masses diagnosed on a computed tomography scan two weeks prior. Based on a high clinical suspicion of adrenal insufficiency, patient was initiated on glucocorticoid and mineralocorticoid therapy prior to laboratory confirmation of adrenal insufficiency. After stabilizing the patient and excluding pheochromocytoma, we proceeded with adrenal biopsy that revealed a nongerminal center-type diffuse large B-cell lymphoma. Our patient was treated with R-CHOP chemotherapy, with good response after 3 cycles but eventually died after the fifth cycle from neurologic complications. This case highlights the notion that primary adrenal insufficiency should be considered in patients presenting with bilateral adrenal masses. Although primary adrenal lymphoma is a very rare adrenal malignancy it should be considered in patients presenting with bilateral rapidly growing adrenal tumors and primary adrenal insufficiency.

Insulinoma is the most common endocrine tumor of the pancreas. The diagnosis suspicion is usually based on clinical symptoms and is confirmed by biochemical tests. Because the majority of insulinomas have a small size, the real problem is the localization of these tumors before surgery. We present the diagnostic and therapy difficulties, the value of available imaging techniques as well as our experience in five consecutive insulinoma patients from our clinic.
