An ultrasound study of the abdomen showed a large well encapsulated mass in the left lobe of liver with caudal exophytic expansion [Fig 1].
CT scan of the abdomen shows the close relation of mass to abdominal wall and liver. Peripheral enhancement of contrast can also be appreciated.

Histologically, on initial evaluation, the mass appeared to be composed of interlacing fascicles of spindle shaped fibroblasts with cartwheel arrangement [Fig 6, 7] suggesting a possibility of fibrous histiocytoma.
Photomicrograph of the mass with high magnification (400X). Staining is done with hematoxylin and eosin.
