Abstract:
Norwegian scabies is a rare clinical variant of human infestation with Sarcoptes sabiei var, hominis, distinguished from the common form of scabies by the presence of remarkable hyperkeratotic scaly crusted skin lesions. We report two cases of Norwegian scabies occuring in a 25-year-old man with merital retardation and in a 9-year-old boy with aplastic anemia, The first case is characterized. by an extensive hyperkeratotic thickening and crusting of the dorsa of hands, knee 8: elbow joints. There is also subungual accumulation of horny rlebris with nail distortion. Histologically, the epidermis shows a mite in straturn comeurn and mild acanthosis in stratum malpighii. Immunoperoxidase for Ig G,M,A is not stained in the clermoepiderrnal junction and capillary wall of upper dermis. The second case shows hyperkeratotic scaly papules and p]aques on the hands, feet, extremities and trunk. 1'he diagnosis vvas confirrned by the demonstration of adults, nymphs, larvas and eggs of Sarcoptes scabiei con the KOH examination of the skin scrapings. hey l3'ords: Norwegian scabies, Mental retardation, Aplastic anemia
