Psoriasiform Keratosis is a rare clinic entity. The etiopathogenesis remains unknown and the disease is characterized by a solitary, scaly or keratotic papule, or plaque mainly located on the extremities. Histopathological features closely resemble those of psoriasis. We report the case of a 70-year-old woman presenting a solitary and asymptomatic keratotic plaque, located on the back of the left leg, unresponsive to topical corticosteroids. We performed an excisional biopsy and histopathology was consistent with psoriasiform keratosis.
