Cushing's Disease Associated with Adrenal Myelolipoma, Adrenal Calcification and Thyroid Cancer

Abstract

A 51-year-old woman with Cushing's disease associated with adrenal myelolipoma is reported. A further characteristic feature was the coexistence of bilateral adrenal calcification and thyroid cancer. Previously several cases of adrenal myelolipoma associated with endocrine dysfunction were reported. The combination of Cushing's disease and adrenal myelolipoma has only been described in two cases of recurrent Cushing's disease but never in an initial occurrence of Cushing's disease. Continued stimulation by excessive adrenocorticotropic hormone (ACTH) not only developed adrenal hyperplasia but also might be involved in the pathogenesis of adrenal myelolipoma. © 1994, The Japan Endocrine Society.
