Primary Intraosseous Mucoepidermoid Carcinoma - A Case Report of 2 Rare Occurrences in the Maxilla

Abstract

Primary intraosseous mucoepidermoid carcinoma arises from ectopic salivary gland tissue present within the jaws. Its rarity presents challenges in diagnosing the condition, especially in young patients. This case report presents two rare cases of primary intraosseous mucoepidermoid carcinoma in the maxilla. The first case is a 27-year-old female with complaints of pain and swelling in the left upper jaw with radiographic images in cone-beam computed tomography revealing a multicystic hypodense lesion and evidence of bicortical expansion and palatal bone perforation. The second case involves a teenager exhibiting similar symptoms and radiographic presentation along with lymph node involvement. This case report highlights the need to consider primary intraosseous mucoepidermoid carcinoma as a differential diagnosis in jaw swellings, irrespective of a patient’s age. Evaluation of volume, cortical involvement, and the internal changes of bony structure precisely with cone-beam computed tomography can help diagnose this condition at the earliest and lead to better prognosis.
