# Bilateral Adrenal Myelolipoma and Breast Cancer in a Patient With Congenital Adrenal Hyperplasia

## TL;DR

A 33-year-old woman with congenital adrenal hyperplasia had both bilateral adrenal myelolipoma and breast cancer, a very rare combination.

## Contribution

This is the second reported case of breast cancer occurring alongside adrenal myelolipoma.

## Key findings

- The patient had giant bilateral adrenal myelolipoma discovered during breast cancer staging.
- Adrenal myelolipoma is rare and often found incidentally, especially in hormonal disorders like congenital adrenal hyperplasia.
- Physicians should be aware of this rare association for proper management.

## 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.
