Allergic contact dermatitis to temporary tattoo by p-phenylenediamine.

Temporary tattoos are widely applied today all over the world. The tattoo makers explain that they use "natural henna paint," although in fact they use "black henna," which includes a mixture of many substances, among them p-phenylenediamine (PPD). There have recently been many reports of allergic contact dermatitis because of temporary tattoo with PPD sensitization. We are adding a new case of temporary tattoo with black henna with an extensive reaction, in which a 12-year-old white boy showed contact dermatitis from PPD, followed by cutaneous eruption after corticosteroid topical treatment.

Necrobiotic xanthogranuloma with lambda paraproteinemia: case report of successful treatment with melphalan and prednisone.

BACKGROUND: Necrobiotic xanthogranuloma (NXG) is a rare non-X histiocytosis with conspicuous lesions on the periorbital skin. METHODS: A diabetic patient presented with NXG and a previous diagnosis of necrobiosis lipoidica on the legs over a period of almost 2 years before the development of the typical lesions of NXG on the periorbital regions, back, thighs and legs. The patient was found also to have developed lambda paraproteinemia. RESULTS: Treatment with melphalan and prednisone resulted in great improvement of cutaneous lesions and paraproteinemia remission. CONCLUSION: This case report details how melphalan and prednisone can be administered in the successful treatment of necrobiotic xanthogranuloma with lambda paraproteinemia.

The authors are showing a retrospective study of 53 cases of lichen striatus concerning sex, colour, age, place of lesions, associated diseases and period of the year of occurrence of the dermatosis. There was a larger number of cases in females of white race and age-between 2 and 5 years old. A greater occurrence was observed in the months of September and March which correspond to spring and summer. Adding the fact that there have been more cases in children, at times in brothers and the trend to spontaneous involution, the authors suggest the possibility of a virus as etiology to this entity.
