The authors report 3 patients affected by psoriasiform acral dermatitis, a distinctive clinical entity characterized by a chronic dermatitis of the terminal phalanges, associated with marked shortening of the nail beds of the affected fingers. The skin biopsy showed in all cases the pathological features of a subacute spongiotic dermatitis. X-ray examination of affected fingers showed no bone or soft tissue changes. Differential diagnosis of psoriasiform acral dermatitis included psoriasis, atopic or contact dermatitis and corticosteroid-induced distal phalangeal atrophy.
