Vaginal masses accompanied by bleeding in infant girls may stem from various benign causes. However, it's crucial to promptly conduct examinations, utilize imaging techniques, and consider excision, especially when rhabdomyosarcoma is a potential concern.

A 18-month girl presented with vaginal bleeding and a mass that had been present since the age of five months. A friable soft mass originating from the posterior vaginal wall was surgically excised, and histopathologically diagnosed as a fibromyxoma, a benign soft tissue tumor.

In prepubertal girls, additional causes of vaginal bleeding and the presence of a mass may include vaginal polyps (fibroepithelial), congenital anomalies, rhabdomyosarcoma, foreign bodies, and urethral prolapse. Fibromyxoma is a type of soft tissue tumor that can manifest in various locations apart from the vagina. It is notable for its propensity for local recurrence even following surgical excision. Therefore, it is crucial to provide parental counseling regarding the necessity for regular follow-up examinations. Notably, the occurrence of fibromyxoma in the vaginal location during infancy has not been previously reported.
