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.
