Primary adrenal lymphoma as a cause of adrenal insufficiency, a report of two cases
Abstract
Summary: Primary adrenal lymphoma (PAL) is a rare cause of adrenal insufficiency. More than 90% is of B-cell origin. The condition is bilateral in up to 75% of cases, with adrenal insufficiency in two of three patients. We report two cases of adrenal insufficiency presenting at the age of 70 and 79 years, respectively. Both patients had negative 21-hydroxylase antibodies with bilateral adrenal lesions on CT. Biopsy showed B-cell lymphoma. One of the patients experienced intermittent disease regression on replacement dosage of glucocorticoids.
Learning points: Primary adrenal lymphoma (PAL) is a rare cause of adrenal insufficiency. Bilateral adrenal masses of unknown origin or in individuals with suspected extra-adrenal malignancy should be biopsied quickly when pheochromocytoma is excluded biochemically. Steroid treatment before biopsy may affect diagnosis. Adrenal insufficiency with negative 21-hydroxylase antibodies should be evaluated radiologically.
