A 31-year-old man presented with a 11-year history of oral ulcers and a 5-year history of erythematous,scaly papules on his lumbar abdomen and extremities. Histological examination showed orthokeratosis with focal parakeratosis,focal necrosis of keratinocytes,and a mild infiltrate of lymphocytes in the epidermis. There were basal cell liquefactive degeneration and colloid bodies,with a moderate lichenoid lymphohistiocytic infiltration in the upper dermis. A diagnosis of keratosis lichenoides chronica was made.
