Introduction: Pleomorphic adenomas are tumors mostly originating from salivary glands. These lesions in the larynx are very rare. Case Report: We report a rare case of pleomorphic adenoma that originated from the mucosal lining, just above the glottic area at the level of the laryngeal ventricle in a 55-year-old female patient. The tumor could not be palpated easily but was observed in the CT scan. We resected the large and firm tumor using trans hyoid pharyngotomy as the surgical approach. Conclusion:  Pleomorphic adenoma in the ventricle of the larynx is an extremely rare lesion. Trans-hyoid pharyngotomy can have good results as the surgical approach in removing such lesions.
