Resumo: Intraosseous mucoepidermoid carcinoma (MEC) is a rare neoplasm of the jaws with uncertain pathogenesis. We present the case of a 48-year-old female patient who underwent evaluation of a bone defect on the left side of the jaw found during a routine imaging exam. The radiological examination reveals a well-defined unilocular radiolucent lesion with irregular margins. An excisional biopsy with an exploratory puncture was performed. Histopathological examination revealed a malignant neoplastic of glandular origin with three distinct cell morphologies: epidermoid, intermediate and mucous. These cells permeate the stroma forming multiple cystic, sometimes filled with mucus and delimited by mucous and intermediate cells. Strong PAS-positivity demonstrated mucin areas. According to these findings, the diagnosis of MEC was established. Although the intraosseous appearance is rare, MEC should be included in the differential diagnosis of bone pathologies.
