Pleomorphic Adenoma of the Upper Lip about a Case
Journal Title: Saudi Journal of Medical and Pharmaceutical Sciences - Year 2018, Vol 4, Issue 1
Abstract
Abstract:The pleomorphic adenoma is a benign tumor of the salivary glands. It accounts for 45 to 65% of benign salivary gland tumors. It develops most often in the main salivary glands, especially the parotid, but it can also reach the accessory salivary glands, such as those of the palate or rarely the upper lip. We report a case of pleomorphic adenoma of the upper lip.Patient of 32 years, admitted in our formation for a painless tumefaction of the upper lip, evolving since 6 months. The clinical examination showed a subcutaneous nodule of the superior white lip, of firm consistency, mobile relative to the underlying planes, about 1 cm in diameter. Surgical excision was performed under local anesthesia with a cutaneous approach and removal of the tumor without breaking the capsule. Histological examination revealed a pleomorphic adenoma. Currently there has been no recurrence after three years of decline.The pleomorphic adenoma is a benign tumor of the salivary glands, its preferential localization is the parotid gland, rarely in the accessory salivary glands. The labial localization is very rare. It mainly affects young adult males, often asymptomatic, slow-growing, of firm consistency, well circumscribed in most cases and closer to the mucosa in relation to the skin. Our case has the particularity of being subcutaneous, which posed the differential diagnosis with a tumor of cutaneous origin. The positive diagnosis is based on surgical excision with histological examination. The potential for recurrence is very important, the excision must be complete with a margin of safety avoiding the major capsular intrusion factor risk of recurrence, and prolonged surveillance is required for the search for recurrence or malignant transformation. Keywords:Tumor, pleomorphic, adenoma, lip.
