Abstract
Introduction: Myoepithelial carcinoma of the submandibular gland is uncommon. Its clinical presentation is nonspecific, making diagnosis and treatment challenging.
Case report: We report a case of a 52-year-old male presenting with a painless swelling in the floor of the mouth.
Clinical and imaging studies initially suggested cystic lymphangioma. Further investigations concluded to myoepithelial carcinoma with lung metastasis. Large tumor resection via a transmandibular lateral pharyngectomy approach was performed, along with a right upper lung lobectomy. Despite aggressive surgery and adjuvant chemoradiotherapy,
local recurrence occurred.
Conclusion: This case highlights myoepithelial carcinoma’s aggressive nature. Vigilant surveillance is imperative, though the risk of recurrence remains high.
