Intraosseous Mucoepidermoid Carcinoma in the Mandible

Table 1

Main pathologies for differential diagnosis.

Lesion	Type	Gender	Mean age (years)	Anatomic location	Clinical signs	Radiological appearance
Central mucoepidermoid carcinoma	Malignant	Female	40	Mandible	Slow growth and painless mass with cortical expansion	Radiolucent (uni-/multilocular) with well-defined borders; Tooth resorption
Cystic adenoid carcinoma	Malignant	Female	40	Palate	Slow growth and painful mass	Bone destruction
Glandular odontogenic cyst	Benign	No predilection	49	Mandible	Small lesions (asymptomatic); Large lesions (bone expansion, pain, and paresthesia)	Radiolucent (uni-/multilocular) with well-defined margins and sclerotic borders
Squamous cell carcinoma	Malignant	Male	40	Mandible	Lesion with a centrally depressed and irregularly ulcerated region	Radiolucent area with poorly defined borders (moth-eaten aspect)
Ameloblastoma	Benign	No predilection	30-70	Mandible	Asymptomatic, but may show bone expansion	Radiolucent (uni-/multiocular); Cortical expansion; Tooth resorption
Keratocyst	Benign	Male	10-40	Mandible	Usually asymptomatic and with no cortical expansion	Radiolucent area with well-defined margins. Anterior-posterior growth through the medullary space
