A rare case of progressive left parotid sialolipoma with parapharyngeal extension: case report

Year: 2025

Type: article

Abstract: Sialolipomas are uncommon benign lipomatous neoplasm of the salivary glands, representing under 1% of parotid tumors. They are typically indolent and asymptomatic, often resembling simple lipomas on imaging. We report the case of a 54-year-old male presented with an asymptomatic enlargement in the left parotid region incidentally discovered. Magnetic resonance imaging displayed a well-circumscribed lipomatous growth sized at approximately 4.6 cm, with incremental growth to 6 cm over three years and involvement of the parapharyngeal space. Due to continued growth and cosmetic concerns, a complete left parotidectomy was carried out with preservation of the facial nerve. Histopathology affirmed sialolipoma. Recognition of this rare entity and its distinction from other similar lipomatous masses, including lipoadenoma, is vital for accurate diagnosis. Full resection yields an excellent prognosis, with recurrence being exceedingly rare.
