Orbital rhabdomyosarcoma in a 19-year-old male patient: A case report and literature review

Rhabdomyosarcoma (RMS) is the most common mesenchymal tumor in children and adolescents, with 10% of cases occurring in the orbits. RMS should be suspected whenever children present with rapidly progressing unilateral exophthalmos. Its symptoms depend on the lesion's origin and location. We report the clinical case of a 19-year-old male patient admitted to the hospital because of blurred vision and bulging eyes that gradually increased over several months. Magnetic resonance imaging showed a mass located mainly in the left orbit, pushing and deforming but not invading the eyeball. The lesion had grown into the left ethmoid sinus wall. The histopathological incisional biopsy results were with alveolar RMS.
