Primary Intraosseous Mucoepidermoid Carcinoma of the Mandible: A Report of a Rare Case

Mucoepidermoid carcinoma(MEC) is the most common primary salivary gland neoplasm.The exact origin of intraosseous MEC remains uncertain and debated.Although rare, intraosseous MEC is the most common and well-recognized intraosseous salivary gland neoplasm.Histopathological examination revealed cystic and solid epithelial components comprising mucous, epidermoid, and intermediate cells, with strong intracytoplasmic mucicarmine positivity, supporting a diagnosis of low-grade primary intraosseous MEC.The patient subsequently underwent hemimandibulectomy at a higher oncology center and remained disease-free during the available follow-up period.The diagnosis of intraosseous MEC presents a diagnostic challenge due to its clinical and radiological resemblance to various benign odontogenic cysts and tumors.We present an interesting case of intraosseous MEC in a 23-year-old female patient.
