A rare case of primary rectal rhabdomyosarcoma in an adult

We report an extremely rare case (1:200 000) of primary rectal rhabdomyosarcoma (RMS) in an adult. In the literature, this case report is the first one dealing with an adult patient. The diagnosis was assessed by computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), endoscopy and histological examination. Neoadjuvant systemic chemotherapy with adriamycin and isofosfamide followed by anterior rectum resection was performed. This article should implicate RMS as a rare differential diagnosis of atypical rectal tumours in adults.
