Vitiligo Combined With Annular Lichen Planus: A Rare Case Report
-
Abstract
A 36-year-old female patient came to our hospital with the chief complaint of having white patches on her waist for 10-plus years and having new annular plaques appearing on the white patches for 6-plus months. Wood's lamp examination done in the hospital showed a positive result. Histopathology of skin tissue from the edge of the annular swelling on the right waist revealed epidermal hyperkeratosis, wedge-shaped thickening of the granular layer, liquefactive degeneration of the basal cells, and a band-like infiltration of lymphocytes in the superficial dermis. The patient was diagnosed with vitiligo combined with annular lichen planus (ALP). The patient was treated with topical halometasone cream administered twice a day. The purplish-red annular plagues subsided and disappeared almost completely one month after the treatment was started and no signs of recurrence were observed duringn the 2-month follow-up. ALP is a rare variant of lichen planus. There has been no reported case of vitiligo combined with ALP so far.
