Concurrent Courses: Exploring the Synchronous Occurrence of Hepatic Myelolipoma and Hepatocellular Carcinoma

Myelolipomas are benign, nonfunctioning neoplasms that most commonly arise in the adrenal glands and constitute a recognisable subset of adrenal masses. They are primarily composed of haematopoietic cells and fatty tissues. Hepatic myelolipoma is extremely rare, with only 11 cases previously recorded in English medical literature. It is usually an incidental finding. Hepatic myelolipomas are most often identified by ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI), and diagnosis is confirmed with histopathology. In this case report, we describe an exceptionally uncommon case in which a patient presented with aberrant and nonspecific symptoms. He was discovered to have a massive hepatic myelolipoma, as well as elements of hepatocellular carcinoma (HCC). He underwent tumour resection after being carefully reviewed by the sarcoma multidisciplinary team (MDT).
