Sarcoma botryoides or botryoid sarcoma[1] is a subtype of embryonal rhabdomyosarcoma, that can be observed in the walls of hollow, mucosa lined structures such as the nasopharynx, common bile duct, urinary bladder of infants and young children or the vagina in females, typically younger than age 8.
The name comes from Ancient Greek botryoid 'grape bunch' due to their gross appearance.
They may appear as a polypoid mass, somewhat yellow in color and are friable: thus, they (possibly) may break off, leading to vaginal bleeding or infections.
New multidrug chemotherapy regimens with or without radiation therapy are now used in combination with less radical surgery with good results, although outcome data are not yet available.
Onset of symptoms occurs at age 3 years (38.3 months) on average.
