A mucocele is a pseudocyst containing spilt mucin from extravasation of the oral minor salivary gland. For this study, 115 cases of mucoceles diagnosed at the Department of Oral Pathology, Seoul National University Dental Hospital were reviewed with respect to gender, age, lesion’s site, size, color, histopathologic features, and recurrence. There was no significant difference between male and female. Nearly 80% cases occurred in young people under the age of 30 (29.7% in the third decade with the highest prevalence). The lower lip (75.7%) was the most common site, followed by ventral surface of the tongue, mouth floor, and buccal mucosa. The lesions measured from 2 to 20 mm in diameter and appeared in various colors. Histopathologically, mucoceles showed pseudocystic cavities containing mucin surrounded by granulation tissues with foam cells. Among the 115cases, 14 showed recurrence on the adjacent sites. Those cases treated with and without removal of the feeding glands on excision of mucoceles showed recurrence rates of 9.2% and 18.0%, respectively. Based on these results, it is recommended that mucoceles be treated with surgical excision of the feeding salivary glands. There were no clinicopathological results significantly different from the established facts regarding the mucoceles of Korean patients
