The grape-like configuration of this lesion is characteristic.
Sarcoma botrryoides (embryonal rhabdomyosarcoma) of vaginaA huge glistening tumor mass is seen filling the lumen of the organ.
Embryonal Rhabdomyosarcoma (sarcoma botryoides) Urinary bladderThis tumor was removed from the forearm with a good margin of muscle around it. The tumor is brown, with a central area of haemorrhage. Wide local resection, wherever possible, is currently accepted as the treatment of choice for malignant soft tissue tumors.
Rhabdomyosarcoma
Gross appearance of alveolar rhabdomyosarcoma. The tumor is embedded within skeletal muscle.
Alveolar rhabdomyosarcoma
Nests of small round cells with scant cytoplasm grouped in nests that are separated by thick fibrous trabeculae. Cells in centers of nests are poorly cohesive & fall away from sides to produce a pattern reminiscent of lung alveoli. See higher power next
Alveolar rhabdomyosarcoma
Note the eosinophilic cytoplasm & the presence of rhabdomyoblasts (malignant giant cells).
Pleomorphic rhabdomyosarcoma with tumor giant cells and tapering cytoplasmic processes (rhabdomyoblasts).Pleomorphic-type rhabdomyosarcoma
