[Acrokeratoelastoidosis].
We record a case of an 18 year old female patient with a history of asymptomatic, keratotic, waxy papules localized over the thenar and hypothenar eminence of palms and the internal aspect of the soles of feet. Histologically they were characterized by hyperkeratosis, acanthosis, elastorrexis and enlarged collagen fibers, typical of the picture known as Costa's acrokeratoelastoidosis. We establish a differential diagnosis with other clinically similar keratotic conditions.
