Composite adenomatoid tumor and myelolipoma of adrenal gland: report of 2 cases

Abstract

Adenomatoid tumor and myelolipoma are benign, hormonally inactive tumors that are often incidental findings in the adrenal glands. Myelolipoma is more common than adenomatoid tumor in this location but both are rare, and as yet, the pathogenesis of both remains unclear. We report 2 cases of composite adenomatoid tumor and myelolipoma, incidentally found in the adrenal gland on investigation for other diseases. To our knowledge, composite adenomatoid tumor and myelolipoma of adrenal gland has not been previously reported.
