Abstract
Mucous cyst is one of the most frequent cystic diseases in the oral mucosa. Most frequent site is a lip, especially lower lip and it is unlikely to be found in the gingiva. We report an unusual case of retention mucous cyst in the mucogingival junction. The patient was a 65-year-old woman who had first noticed the lesion 1 month earlier. As a cystic lesion was observed in her lower right mucogingival junction, it was surgically resected. Histopathologically, the lesion was diagnosed as mucous cyst with epithelial lining.
