Uterine alveolar rhabdomyosarcoma in an elderly patient manifesting extremely poor prognosis; a rare subtype of rhabdomyosarcoma.

Alveolar rhabdomyosarcoma (ARMS) arising in the corpus uteri is an extremely rare condition with exceptionally rapid progression and poor prognosis. Furthermore, ARMS is primarily diagnosed in the pediatric population. Due to rarity of the disease, there are no standard treatment guidelines. A 90-year-old woman was presented with a huge pelvic mass causing dyspnea and abdominal distension. The patient underwent debulking surgery and was diagnosed with uterine ARMS by fresh specimen biopsy. Despite intensive postoperative care, the patient died on the eighth postoperative day. Here, we report a case of uterine ARMS that will add to our understanding of this exceptionally rare type of tumor.
