The nasoalveolar region is an uncommon area of all rhabdomyosarcoma (RMS) cases. RMS has a bimodal distribution in children, occurring in those aged two to four years and 12 to 16 years. The authors presented an unusual case of alveolar RMS that presented at a young age, in an uncommon region, with an atypical presentation, and imaging findings mimicking organized hematoma and complicated nasoalveolar cyst. Confounding as a result of the presence of trauma can delay diagnosis and treatment.
