A metastatic gastric tumor originating from a pleomorphic rhabdomyosarcoma of the extremity: a case report and literature review

Pleomorphic rhabdomyosarcoma is a rare and aggressive variant of rhabdomyosarcoma that usually occurs only in adults aged 45 years or older. Gastric metastasis from a soft-tissue sarcoma of the extremity is likewise very rare, with only a few previously reported cases. Here, we describe the case of a 52-year-old man with gastric metastasis who underwent en bloc excision of the primary tumor and distal gastrectomy but died 6 months after surgery due to lung metastases. This is, to our knowledge, the first reported case of gastric metastasis from pleomorphic rhabdomyosarcoma of the extremity. In cases such as these, patients may have widespread disease, and thus, surgery may only have a limited role in its management.
