Myopericytoma of the liver: A rare tumor - A case report

Year: 2025

Type: article

Abstract: INTRODUCTION: Myopericytoma is an uncommon benign neoplasm composed of myoid-appearing perivascular cells. It had been reported in various soft tissues, but only few case reports were found reported in liver. CASE PRESENTATION: We reported a case of myopericytoma in a 43-year-old female with a history of a left adnexal cyst and foul-smelling per vaginal discharge with no significant findings in per abdominal examination. Imaging studies initially suggested the possibility of hemangioma in ultrasonography and further CT scan was advised which gave the possibility of focal nodular hyperplasia. CLINICAL DISCUSSION: Right hemihepatectomy was performed and histopathological examination revealed a well-circumscribed mass consistent with myopericytoma, supported by positive immunohistochemical staining for SMA and H caldesmon, and negativity for Desmin, DOG-1, and ALK. CONCLUSION: This case contributes to the limited literature on hepatic myopericytoma and emphasizes the importance of considering this entity in the differential diagnosis of liver lesion.
