case_images: Multiple superficial mucoceles at the lower labial mucosa (a) and at the soft palate with no OLP lesion (b). White striation, erythema, and ulcerated areas at the bilateral buccal mucosa with superficial mucoceles in the adjacent area (c, d).

case_images: Upon examination, multiple tense and fluid-filled vesicles 1-4 mm in diameter were observed on the upper and lower labial mucosa, buccal mucosa, ventral surface of the tongue, left retromolar trigone, and soft palate (Figures 1(a) and 1(b)). White striation, erythema, and ulcers were found on the edentulous ridge's mucosa and the bilateral buccal mucosa (Figures 1(c) and 1(d)).
case_images: Extraoral examination revealed a polygonal purple papule with white striation on the dorsal surface of the foot (a) and dystrophic toenails (b, c).

case_images: Extraoral examination revealed polygonal and purple papules with white striation on the extensor surface of both legs and the dorsal surface of both feet (Figure 2(a)). Both of her toenails also showed dystrophy (Figures 2(b) and 2(c)).
case_images: Histopathologic features of superficial mucoceles illustrated an intraepithelial vesicle containing mucin pool with scattered lymphocytes (original magnification, 100x) (a). Histopathologic features of OLP showed basal cell degeneration with subjacent inflammatory cell infiltrate. The arrows indicate civatte bodies (original magnification, 400x) (b).

case_images: Histopathologically, the specimen showed intraepithelial vesicles containing a mucin pool with scattered lymphocytes (Figure 3(a)). The histological features showed a subepithelial infiltration of lymphocytes and macrophages as well as basal cell degeneration with civatte bodies, confirming the diagnosis of OLP (Figure 3(b)).
case_images: Clinical illustration after 8-month treatment period; complete resolution of superficial mucoceles at the lower labial mucosa (a) and the soft palate (b). Remission of OLP lesions at the bilateral buccal mucosa (c, d).

case_images: However, after an 8-month-treatment period, the superficial mucoceles showed complete resolution, and the patient was satisfied with this outcome (Figures 4(a)-4(d)).
