Two boys, age 7 and 9 years, with the diagnosis of primary anetoderma
are presented. In one patient a growing number of indolent lesions dev
eloped for one year on the neck. The other boy complained of single le
sions appearing over four months on the arms, feet, and chest wall. In
dividual lesions measured up to 1 cm in diameter and showed a palpable
herniation phenomenon and wrinkled surface. The lesions did not have
an inflammatory onset. Histologically, in both patients the diagnosis
of anetoderma was verified by loss of elastic fibers and a lymphohisti
ocytic infiltration in the middermis. Administration of oral penicilli
n for three weeks did not result in marked improvement, and atrophic m
acules continued to appear in the younger boy. Although no autoimmonol
ogic abnormalities or other associated diseases have arisen in our pat
ients, long-term follow-up is mandatory to detect autoimmune disorders
that are reported to occur in the course of the disease.
