Odontogenic myxoma (OM) is a benign neoplasm often affecting mandibular molars. Although small tumors may be asymptomatic, bigger lesions may result in bone swelling, and aggressive cases show fast growth. Radiographies show unilocular lesions, multilocular lesions, and bone trabeculae arranged at right angles, with irregular margins and dental displacement/resorption. Sometimes soap bubbles appearance is present. A 50-year-old male patient was referred for examination of an asymptomatic radiographic finding in the right mandible.
Cone beam computed tomography showed an irregular hypodense area, with poorly defined margins, in the right mandibular body extending to the anterior region, with small cortical expansion. After incisional biopsy, the histopathologic analysis showed proliferation of spindled- and stellate-shaped cells in an abundant loose and myxoid stroma. The diagnosis of OM was given. Subsequent hemimandibulectomy was performed for total tumor excision. The patient remains in follow-up.
