Abstract
Pleomorphic adenomas of the submandibular glands are rare, and their treatment usually involves excision of the whole gland along with the tumor. A 24-year-old male patient presented with the main complaint of an extensive slow-growing painless swelling in the submandibular region. Physical examination showed a palpable, rounded, and mobile mass. Computed tomography showed a well-circumscribed lesion in the topography of submandibular gland. Fine needle aspiration was suggestive of pleomorphic adenoma. Partial sialoadenectomy of the submandibular gland with safety margins was performed through submandibular transcutaneous access. The postoperative period was uneventful and no facial or hypoglossal nerve damage or salivary flow alterations were observed. Histopathologic examination revealed a fragment of encapsulated benign neoplasm of glandular origin, composed of rounded myoepithelial cells in the middle of a predominantly chondromyxoid stroma, confirming the diagnosis of pleomorphic adenoma. Partial sialoadenectomy represents a safe and more conservative approach to benign submandibular gland tumors.
