Abstract

Keratosis lichenoides chronica is a rare dermatosis of unknown etiology with a wide variety of cutaneous manifestations. We present a 47-year-old male with a history of progressive and recalcitrant hyperkeratotic and warty plaques, mimicking verrucous secondary syphilis both clinically and microscopically. We review the clinical manifestations, microscopic features, and treatment modalities for this rare and distinctive dermatosis.
