Allergic contact dermatitis to nitroglycerin has been previously reported. A localized cutaneous burn-like reaction due to the transdermal device was recently described. We are presenting a case of recurrent allergic contact dermatitis due to nitroglycerin as well as to its delivery device, resulting in numerous patches of postinflammatory hypermelanosis at the sites of application.

SUMMARY The isolation of Trichophyton soudanense outside of Africa has been reported relatively infrequently and in single cases only. As far as we know widespread infection within white families has not previously been noted. We have isolated T. soudanense from seven individuals in a family of ten, from three of seven members of a second family, and from a classmate of one of the affected children in the first family.

Two cases of aplasia cutis congenita are presented. The first case was in a child with a localized defect on her scalp. The second case was in an adult male who had extensive symmetrical involvement of his trunk and thighs, two lesions on the scalp and dystrophic changes in his nails. Nail dystrophy associated with aplasia cutis congenita has been described only once previously.
