case_images: On performing an abdominal contrasted enhancing computed tomography (CECT), a large lobulated mass lesion measuring 6.9 x 7.3 x 6.7cm was identified involving the ligamentum teres and segments II, VII, IVa, caudate lobe of the liver, and (Figure 1).
case_images: Gross image of the slices of the liver showing a large mass in the right lobe reaching up to the liver capsule with central hemorrhagic areas. Scale bar= 10cm.

case_images: A relatively circumscribed lesion, measuring 10 x 8 x 7cm, was identified in the region of ligamentum teres and involving the liver (Figure 2).
case_images: A - A well-circumscribed tumor is seen, sharply demarcated from the normal liver (lower left part) (H&E, x40); B - The tumor cells are arranged in fascicles (H&E, x100); C - Tumor cells are epithelioid in shape and have clear to pale eosinophilic cytoplasm (H&E, x200); D - At places, the tumor cells are arranged in a whorling pattern around blood vessels (H&E, x200).

case_images: These tumor cells had clear to eosinophilic cytoplasm, fine chromatin, and conspicuous micronucleoli (Figures 3A-D).
case_images: The tumor cells show strong expression of smooth muscle antigen (A - immunohistochemistry, x200), HMB-45 (B - immunohistochemistry, x400), and MelanA (C - immunohistochemistry, x400). (D) CD34 stain highlights the capillaries, while the tumor cells are negative (immunohistochemistry, x200).
