Case Report

A 13-year-old boy presented with low-grade fever, upper abdominal pain, loss of appetite, and weight loss for 2 months, with a history of swelling in his upper abdomen for 15 days. On examination, a 17 x 20-cm intraabdominal, smooth, firm, non-tender swelling was noted occupying epigastric and left hypochondrium. The mass moved with respiration, and finger insinuation between mass and right coastal margin was not possible. There was no ascites and further examination was unremarkable. Liver function tests and α-fetoprotein were normal.

left lobe of liver, with multiple vascular structures traversing the lesion suggestive of hepatocellular carcinoma.

CT scan of the abdomen showed a homogenously enhancing mass lesion of 14.9 x 12.9 cm in the left lobe of the liver with multiple vascular structures traversing the lesion consistent with hepatocellular carcinoma (Figure 1). Non-anatomical left hepatectomy was done. Intraoperative examination revealed a 15 x 20-cm lesion arising from the inferior aspect of the left lateral segment of the liver, adhered to the stomach along the lesser curvature (Figure 2). Cut specimen showed solid tumor with cystic areas of hemorrhage and multiple vascular structures traversing the tumor (Figure 3).

Postoperatively, 1 unit of packed red blood cell transfusion was given and the patient was discharged on postoperative day 8. Histopathological examination reported a tumor predominantly showing spindle cells arranged in sheets embedded in myxoid stroma. Vimentin was strongly positive. Desmin, carcinoembryonic antigen, and α-fetoprotein were negative. This suggested undifferntiated embryonal sarcoma of liver (USEL; Figure 4), a rare, highly malignant neoplasm that is more common in children. Bone scan was normal. Adjuvant chemotherapy was given. The patient is now asymptomatic on regular follow-up. We stress the role of histopathology and IHC in diagnosing UESL and of timely en bloc resection and postoperative chemotherapy in improving survival rates.
