RESUMO
The authors report a case of a rare facial myxoma arising from the maxillary sinus in a 20-month-old child. The diagnosis was confirmed by a biopsy, and the patient underwent a partial maxillectomy to achieve a total resection of the mass due to the locally aggressive nature of the lesion. Myxomas should be differentiated from malignant sarcomas, in particular embryonal rhabdomyosarcoma, which can arise from the same location and require multimodality therapy consisting of surgery, irradiation, and chemotherapy.
