Vulvovaginal rhabdomyosarcoma is a rare vulvovaginal tumour, a highly malignant soft tissue sarcoma composed of cells with round to oval or spindle-shaped nuclei and eosinophilic cytoplasm that may show differentiation towards striated muscle cells. It usually affects children and presents with a vulvar or vaginal mass that may be polypoid or grape-like (embryonal subtype) and associated with bleeding and ulceration. [from
