Sarcoma botryoides pathophysiology

Overview
Sarcoma botryoides, also known as embryonal rhabdomyosarcoma, is a type of rhabdomyosarcoma in the vagina of young girls, typically younger than 8. The name comes from the gross appearance of "grape bunches" (botryoid in Greek).

Pathophysiology
Under the microscope one can see rhabdomyoblasts that may contain cross-striations. Tumor cells are crowded in a distinct layer beneath the vaginal epithelium, named the cambium layer.
