We report a rare case of large radicular cyst considered to have occurred from the left maxillary lateral incisor and grown into the left maxillary sinus. The patient was a 29-year-old man. He visited us complaining of swelling on the left buccal region. There were slightly swelling and oppressive pain on left buccal region at the time of initial presentation. On examination of the oral cavity, the mucolabial fold of left upper anterior teeth was found slight swellen. The left upper lateral incisor was a non-vital tooth and moved toward palatal side and had slight percussion pain. The radiograph features showed a well-defined, circular, radiolucent legion in the left maxilla. Computed tomography demonstrated the water-density area in left maxillary sinus. Under general anesthesia, surgical intervation was employed. The dimension of the cyst was 50×45×30mm. Histopathologically, the cyst wall was lined by squamous epithelium and sinusal mucosa was thickened due to edema.
