Pleomorphic adenoma is the most common tumor of the salivary glands. Its occurrence in the submandibular gland is uncommon. This study reports a case of pleomorphic adenoma in the submandibular gland. An 81-year-old female patient presented with a 2-year history of painless swelling on the left submandibular region. No clinical sign was observed on intraoral examination. Computed tomography showed a large well-defined encapsulated hypodense swelling. Surgical excision of the tumor was performed under general anesthesia and the encapsulated tumor was excised. The specimen was sent for histopathologic examination and showed the proliferation of epithelial and plasmocytoid myoepithelial cells, ductal elements with pairs of cells, and areas of cyst formation. The patient's postoperative course was uneventful. No recurrence was observed after 6-month follow-up. Knowledge of the clinicopathologic variety of pleomorphic adenoma is of great importance for early diagnosis and suitable treatment.
