Gigantic submandibular pleomorphic adenoma: A rare case report

Introduction: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. When neglected on some occasions, its size and weight can enormously augment. Case presentation: We report a case of a giant submandibular pleomorphic adenoma in a 75 years old female patient which measured 34 × 26 × 20 cm and weighed 8.1 kg. Conclusion: Neglecting such tumors without treatment, can cause severe facial disfigurement and can even hinder the airway.
