The Gianotti-Crosti syndrome.

The Gianotti-Crosti syndrome is an infrequently recognized disorder with distinctive characteristics. The eruption, which lasts for two to eight weeks, consists of large, flat-topped, nonpruritic papules on the face, buttocks, and limbs. Its onset may be preceded by fever and upper respiratory tract symptoms. Associated findings include generalized lymphadenopathy, anicteric hepatitis, and HBs antigenemia. Two children with the syndrome are described to bring this entity to the attention of pediatricians.
