Mucoepidermoid carcinoma of the lower lip: A case report and review of literature

Abstract

Mucoepidermoid carcinoma (MEC) is a rare salivary gland malignancy characterized by diverse cellular components. This case report presents a unique instance of low-grade MEC in a 28-year-old female, emphasizing the importance of accurate diagnosis and tailored management. The patient exhibited a painless, enlarging lower lip swelling over a year, with imaging suggestive of a fibrolipomatous lesion. Surgical excision was successfully performed, with subsequent histopathological analysis displaying mucinous cystic spaces, varied epithelial cell types and other characteristic features consistent with MEC. The case findings aligned with hallmark MEC features are seen in established literature, highlighting the significance of precise diagnosis and grading for appropriate management. This report contributes to the understanding of MEC’s varied presentations and underscores the importance of thorough: histopathological examination, lower lip, mucoepidermoid carcinoma clinical evaluation, accurate histopathological analysis and interdisciplinary collaboration. The case highlights the value of considering MEC in younger patients, even with atypical presentations, and encourages ongoing exploration of diagnostic and therapeutic strategies to improve patient outcomes.
