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

A ten-year-old female Yorkshire terrier was presented to Veterinary Medical Center, Chungbuk National University with signs of anorexia and cough. Blood electrolytes, complete blood count (CBC), and hormone analysis revealed mild elevated lipase and bile acid, moderate hypercholesterolemia and severe elevated alanine transaminase (ALT), alkaline phosphate (ALP), and gamma-glutamyl transferase (GGT). Survey radiographs revealed the potbelly-shaped abdomen, generalized hepatomegaly, and round and smooth marginated mass in right upper abdomen. On ultrasonography, enlarged gallbladder with combination of kiwifruit-like and stellate pattern consistent with gallbladder mucocele was revealed. On day 113 after diagnosis of gallbladder mucocele, free fluid and the hyperechoic structure mainly in the dorsolateral region of the gallbladder was found, which was consistent with gallbladder rupture. Cholecystectomy was performed after gallbladder rupture.
