Six cases of myxoma of the jaw were studied clinicopathologically. The subjects included four males and two females aged 16-59 years (mean 34.5 years). Tumors developed in the mandibule in all cases and were located between unilateral anteriors and molars in three cases, in the unilateral molar region in one case and between bilateral molars in two cases. Expansion of the mandibular bone was noted in each case. Radiographically, multilobular and unicystic appearances were observed in two and four cases respectively. No case revealed impacted teeth. Two cases each were treated by partial mandibular resection, regional resection, and enucleation with curettage. Follow-up was performed from nine months to two years and nine months for each case, and there has been no evidence of recurrence. Histologically, tumors revealed sharp spindle cells arranged in regular or random directions in the background of loose, mucoid-rich stroma. A case showed cystic structures, including mucoid materials, and another was rich in odontogenic epithelia.
