Tissue origin: 1. omentum. 2. porta hepatis lymph node. 3. porta hepatis mass.
Diagnosis: Omentum, porta hepatis lymph node and porta hepatis mass; biopsies: Consistent with embryonal rhabdomyosarcoma. The tumor cells are positive for desmin, myogenin (focal) and glypican-3. They are negative for pan-CK, SALL4 and heppar1 immunostains.
