We present a woman with a history of years of evolution of confluent hyperkeratotic papules and plaques with a generalized linear and reticulate pattern. Histopathological characteristics concordant with keratosis lichenoides chronica were finally evidenced after several non-specific biopsies. The cutaneous manifestations, chronicity. histopathology findings, and refractoriness to therapies are typical of this rare dermatosis.
