Rare Cause of Pelvic Mass: Hepatocellular Adenoma

OpenAlex İngilizce

Introduction: Hepatocellular adenoma (HA) is a rare solitary tumor originating from liver cells. There have been no reported cases with pelvic localization in the literature. In this article, we present a case of HA presenting with a pelvic mass. Case: A 24-year-old male patient was found to have an intraabdominal mass on ultrasound during routine health screening. MRI (Magnetic Resonance Imaging) showed a solid mass lesion with pelvic localization, extending towards the upper abdomen, measuring approximately 16.5x8 cm, with sharp margins and well-defined borders, primarily suggestive of sarcomatous pathologies (rhabdomyosarcoma? / embryonal sarcoma?). Exploration revealed a mass resembling liver tissue attached to the left lobe of the liver via the falciform ligament, which was excised along with the ligament. The pathology of the specimen was consistent with adenoma. The patient was discharged on the third day postoperatively. Follow-up MRI at six months postoperatively did not reveal any issues. Discussion and Conclusion: In patients with no significant etiological factors such as oral contraceptive use or anabolic androgen use, genetic studies and identification of possible environmental etiological factors from appropriate case series will contribute significantly to the literature. Our case demonstrated that even in male patients, HA should be considered in the differential diagnosis of intraabdominal masses.
