CASE PRESENTATION:
We report a case of LP following BNT162b2 vaccination in a 59-year-old
woman with a past history of LP. Two weeks after the second dose of
vaccine she presented for newly appeared pruritic skin lesions. She
reported no mucosal nor nail lesions, recent infections, habit changes,
nor other possibl triggers.
Six years earlier she presented similar, more generalized, papules,
clinically and histologically diagnosed as LP, and effectively treated
with topical corticosteroids. Lesions had never recurred.
At physical examination, polygonal, purpuric, scaly and slightly
elevated papules were seen on the medial side of both ankles and feet
(Fig. 1). Close-up examination and dermatoscopy evidenced fine scales on
an erythematous background and Wickham’s striae (Fig. 2).
Biopsy confirmed the diagnosis of LP and lesions resolved after three
weeks of topical high-potency corticosteroids, with relief of the
patient.
