Abstract:

Schwannomas are benign tumors originating from Schwann cells of the peripheral nerve sheath, frequently occurring in the head and neck region. However, involvement of the palatine tonsil is extremely rare, with fewer than ten cases described in the literature. We report the case of a 20-yearold female presenting with dysphagia and dyspnea in the supine position. Clinical evaluation and imaging revealed a pedunculated mass arising from the left palatine tonsil. Surgical excision was performed, and histopathological examination confirmed the diagnosis of schwannoma, supported by positive S100 immunostaining. This case underscores the importance of considering schwannoma in the differential diagnosis of tonsillar masses. Surgical excision remains the treatment of choice with excellent prognosis.
