Dermoscopy of oral mucocele: three types of extravasation mucoceles

Abstract

Background/aim: Dermoscopy is a diagnostic tool that assists in imaging the epidermis and dermis. Although it has also started to beused to diagnose nonmelanocytic lesions recently, it has not been tested much on oral mucosal masses, such as oral mucoceles. Thisstudy aimed to investigate whether dermoscopy is a valuable tool in diagnosing oral mucoceles.Materials and methods: In this study, the clinical and dermoscopic features of 21 oral mucocele lesions of 21 patients (11 females, 10males) aged between 6 and 38 years who were confirmed histopathologically were evaluated.Results: Of the lesions studied, 95.2% (20) were extravasation and 4.8% (1) were retention mucoceles. The nonvascular structureswere determined as white areas (61.9%, 13), erythema (57.1%, 12), purplish-gray background (52.3%, 11), ulcer (30%, 8), yellowishorangeareas (23.8%, 5), crust (14.2%, 3), starburst pattern (0.95%, 2), and bleeding (0.47%, 1). Dermoscopically, 40% of extravasationmucoceles were classified as type 1 (8 patients), 25% as type 2 (5 patients), and 35% as type 3 (7 patients).Conclusion: We concluded that there are 3 types of extravasation mucoceles dermoscopically and clinically, and these types may bestages of transition between each other.
