A 15-year-old boy presented with a swelling on the lower lip for the past 1 month. It was progressively increasing in size and was asymptomatic. The patient gave history of repeated lip biting. On examination, a single slightly bluish, soft, fluctuant nodule (4 × 5 mm) was present on the lower lip [Figure 1]. Rest of the muco-cutaneous examination was noncontributory. Dermoscopy [Dino-Lite AM413ZT, Polarizing, New Taipei, Taiwan] was done using the method suggested by Jakhar et al. Dermoscopy revealed a shiny surface with extensive vascular network (both linear and branched vessels) and intervening white structureless areas [Figure 2]a and [Figure 2]b. On the basis of history, typical location, and clinical examination, a diagnosis of mucocele was made. The lesion was surgically excised [Figure 3]a and sent for histopathology. Histopathology revealed a mucous extravasation cyst in the dermis with mucinophages and mucin in the lumen [Figure 3]b. The mucocele was lined by the granulation tissue (devoid of epithelial lining), infiltrated by histiocytes and inflammatory cells.

Mucocele is a mucous-filled cyst caused by accumulation of mucous secondary to alterations in minor salivary glands., Lower lip is the most common site in oral cavity, and the most probable etiology includes lip biting or trauma. The diagnosis is usually clinical., Dermoscopy of the mucosa and its pathology has been termed as mucoscopy. The existing dermatoscopes are not designed to perform mucoscopy as swiftly as dermoscopy. Jakhar et al. have suggested an innovative technique of performing mucoscopy and the same technique was used in our patient. The shiny surface of the mucocele and extensive vascular network on mucoscopy appears because of stretching of the overlying tissue and vascular congestion. The white structureless areas correspond to the hyperplastic epithelium. The differentials of mucocele include fibroma, lipoma, oral lymphangioma, and benign or malignant salivary gland tumors., Here, an attempt has been made to describe the dermoscopic features of mucocele and further studies may be needed to substantiate the findings.
