SUMMARY A 66‐year‐old male presented with keratosis lichenoides chronica after a presumed drug‐induced erythroderma. After resolution of the erythroderma, slightly scaly erythematous and violaceous papules in a reticular arrangement over the trunk and limbs developed in association with hoarseness, palmoplantar keratoderma, onycholysis and subungual keratosis. Histology from a lichenoid lesion showed pseudo‐epitheliomatous hyperplasia, hyperorthokeratosis, parakeratosis, dyskeratosis, neutrophil exocytosis and focal vacuolar degeneration of the basal layer of the epidermis. There was a band‐like chronic inflammatory infiltrate in the upper dermis. The skin improved with prednisone 40 mg/day for 15 days, leaving atrophic hypopigmented scars. A diagnosis of keratosis lichenoides chronica was made.
