Abstract :This case report aimed to explain the diagnosis and treatment of a radicular cyst that is located on the palate, expands towards the nasal cavity, and causes breathing difficulty in the patient because it puts pressure on the nasal cavity. A 17-year-old female patient presented to our clinic with palatal swelling and difficulty breathing. Intraoral examination revealed a lesion on the right side of the hard palate that spread to the base. Radiographic examination revealed a unilocular radiolucent lesion with loss of border definition involving the roots of the right maxillary first molar. Since the clinical appearance was characteristic of minor salivary gland tumors, the differential diagnosis included pleomorphic adenoma. In aspiration biopsy, cyst fluid was aspirated from the lesion and the preliminary diagnosis was revealed as an odontogenic cyst. Due to the large size of the cyst, treatment was started with surgical marsupialization and incisional biopsy to protect the surrounding anatomical structures. The biopsy result was a benign inflamed cyst. The lesion was excised completely in the 6th month. Any recurrence was observed at a 1.5-year follow-up.
