Multifocal contact dermatitis to nitroderm TTS 5 with extensive postinflammatory hypermelanosis.

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.

Keratoacanthoma arising in stasis dermatitis.

A case of keratoacanthoma arising in stasis dermatitis is presented. The eczematous dermatitis was aggravated by episodes of deep tissue inflammation, yet the common course of the tumor was not altered. To our knowledge, this is the first report of a keratoacanthoma arising in stasis dermatitis.

Cholinergic urticaria. A seasonal disease.

Nine young patients with cholinergic urticaria reported that the occurrence of the disease was restricted to winter. They were examined in a climatic room in winter and summer under three climatic conditions in each season (cold, comfort, and severe heat). All subjects experienced severe phenomena of cholinergic urticaria during the winter season when tested under comfortable climate and under severe heat load.
