Abstract
Background/aimDermoscopy is a diagnostic tool that assists in imaging the epidermis and dermis. Although it has also started to be used to diagnose nonmelanocytic lesions recently, it has not been tested much on oral mucosal masses, such as oral mucoceles. This study 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, 10 males) aged between 6 and 38 years who were confirmed histopathologically were evaluated.ResultsOf the lesions studied, 95.2% (20) were extravasation and 4.8% (1) were retention mucoceles. The nonvascular structures were determined as white areas (61.9%, 13), erythema (57.1%, 12), purplish-gray background (52.3%, 11), ulcer (30%, 8), yellowish-orange areas (23.8%, 5), crust (14.2%, 3), starburst pattern (0.95%, 2), and bleeding (0.47%, 1). Dermoscopically, 40% of extravasation mucoceles 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 be stages of transition between each other.

Summary
Oral mucoceles are the most frequently observed benign lesions of the minor salivary gland and are formed as a result of any mechanical trauma on the discharge duct of the salivary gland. Extravasation mucoceles emerge as a result of the extravasation of salivary gland secretions from the salivary gland duct into the soft tissues around the gland. The obstruction of the salivary gland ducts, which leads to the reduction or absence of glandular secretion, causes RM [3,4]. These are accepted as separate from each other since each has a unique pathogenesis and microscopic properties [5]. While the lesions are more common in the internal part of the lower lip, they may be present on the buccal mucosa, tongue, and floor of the mouth [6,7,8]
