To the Editor, Hemolymphangioma is an extremely rare benign tumor originating from mesenchymal tissue, possibly due to developmental defects or abnormalities in vascular and lymphatic formation. They can occur at any age and affect any part of the body; 90 % occur in children under 2 years old, with rare incidence in adults. Abdominal hemolymphangioma constitutes less than 5 % of all lymphatic vascular tumors. Reported locations in the literature predominantly include the head and neck, spleen, pancreas, esophagus, stomach, small intestine, colon, rectum, and rarely retroperitoneal areas.1e4 Here, we report a case of hemolymphangioma located at the confluence of the gonadal veins and the inferior vena cava in the retroperitoneum, managed surgically.
