ABSTRACT
Adrenal myelolipoma is a rare, benign tumor of the adrenal gland, typically non-functional, asymptomatic and unilateral. With the increased use of radiological imaging, it has been discovered more frequently as incidental mass. It is common to occur concurrently with hormonal dysfunction conditions like congenital adrenal hyperplasia. However, there are few previous reported cases of malignancy concomitant with adrenal myelolipoma. We present a case of a 33-year-old patient diagnosed with congenital adrenal hyperplasia since birth. She was diagnosed with giant bilateral adrenal myelolipoma incidentally during the investigation done for staging her breast cancer. To the best of our knowledge, this is the second reported case of breast cancer concomitant with adrenal myelolipoma. Although this entity is very rare, physicians should be familiar with such rare adrenal masses and their associations in order to manage them appropriately.
