case_images: A 44-year-old male presented with a four-month history of a raised and scaly plaque over the medial aspect of lower lip followed by the appearance of two similar lesions over the right lateral aspect of the same lip (Figure 1).
case_images: A and B, Dermoscopy (polarized dermoscopy, original magnification x20) of lateral and medial lesions showing linear Wickham striae (white arrowhead) and circular Wickham striae (blue arrowhead), scaling (black arrowhead), and violaceous background (red arrowhead). C, Histopathology (hematoxylin-eosin, original magnification x40) showing hyperkeratosis, basal vacuolar degeneration, and prominent band-like lymphocytic infiltrate. D, Dermoscopy of medial lesion after 14 days of treatment showing significantly reduced amount and thickness of Wickham striae (green arrowhead)

case_images: Diffuse scaling and violaceous background were seen in dermoscopy of both lesions (Figures 2A,B). A punch biopsy was performed from the lateral lesion and the histology showed hyperkeratosis, basal vacuolar degeneration, and prominent band-like lymphocytic infiltrate (Figure 2C). The medial lesion was re-evaluated by dermoscopy on the 14th day which revealed a significant reduction in the amount and thickness of the WS and scaling was almost absent (Figure 2D).
