Adrenal Pseudocyst as a Result of Longterm Intake of Steroid Hormone

ABSTRACT

Adrenal pseudocysts are uncommon lesions which usually occur as a result of hemorrhage within the adrenal tissue. Adrenal hemorrhage is usually associated with severe stress, sepsis, pregnancy, syphilis, leukemia, or anticoagulant therapy but during steroid therapy, it is very rare. We report a case of adrenal pseudocyst that resulted from hemorrhage into the adrenal gland and is probably related to the exogenous administration of steroids. The patient was a 57-year-old woman who was treated with oradexon for 20 years for the treatment of a maculopapular lesion on her thigh as well as for arthritis. She underwent a right adrenalectomy due to the adrenal cystic mass. The wall of the cystic mass was composed of a thick layer of hyalinized fibrous tissue with remnants of adrenal cortical tissue on the outer aspect. The inner surface had no lining cells and the wall of the cyst contained many calcified plaques with hemosiderin pigment.
