Abstract

Hemangiolymphangioma is a rare venolymphatic vascular malformation characterized by networks or proliferations of vascular spaces—such as lymphatics, capillaries, veins, or arteries—lined by bland endothelium and embedded in connective tissue stroma. Due to its rarity, the literature contains only a few documented cases of this condition. This case report details an 8-year-old girl who presented with abdominal distension since past 1.5 years. Imaging modalities, including ultrasonography and CECT of the abdomen, suggested a mesenteric cyst. The patient underwent exploratory laparotomy and excision of the mesenteric cyst. Histopathological analysis of the specimen confirmed the diagnosis of hemangiolymphangioma of the mesentery, further validated by immunohistochemistry. This case highlights the key aspects and histopathological features of this rare condition.
