Endoscopic ultrasound-guided fine-needle aspiration of metastatic alveolar rhabdomyosarcoma to the pancreas with fluorescence in situ hybridization: a case report.

Alveolar rhabdomyosarcoma (ARMS) is a rare tumor in adults. Cytologic diagnosis of metastatic ARMS to the pancreas diagnosed by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been reported rarely in the literature. A 20-year-old male with a history of ARMS in the right maxillary sinus resected one year earlier and pancreatitis treated two months earlier, presented on routine follow-up.
