Abstract:
Carcinosarcoma is a highly malignant tumor characterized by dual malignant histologic differentiation of epithelial and mesenchymal components, which rarely occurs in the maxillary sinus. We experienced a case of carcinosarcoma mixed with a keratinizing squamous cell carcinoma and an osteosarcoma arising from the right maxillary sinus recently. A 55-year-old male patient presented with right nasal obstruction and epistaxis. The initial punch biopsy revealed a high-grade sarcoma, favoring an osteosarcoma. After general evaluation, the patient was staged as cT4aN0M0. The patient was treated by right total maxillectomy, radiotherapy, and chemotherapy. We present with a review of the literature a case of a carcinosarcoma originating from the right maxillary sinus that had invaded into the orbital cavity and protruded into the nasal cavity.
