A systemic reaction to patch testing for the evaluation of acute generalized exanthematous pustulosis.

BACKGROUND: Patch tests are considered safe but adverse reactions have been reported. OBSERVATIONS: A case of acute generalized exanthematous pustulosis (AGEP) provoked by a patch test with acetaminophen is described. Of special interest are the negative patch test results obtained with the offending drug. The case is discussed against the background of the putative mechanisms of AGEP and the reported systemic reactions to patch testing for AGEP. CONCLUSIONS: To our knowledge, this is the first report in the English-language literature of a generalized AGEP-like reaction caused by patch tests carried out to determine the drug eliciting AGEP.

PEMPHIGUS: an acronym for a disease with multiple etiologies.

The acronym PEMPHIGUS is suggested to encompass the numerous factors involved in the pathogenesis and course of the disease. In the following review the authors present studies documenting these factors. The acronym can serve as a handy tool to direct the physician's investigation of a case of pemphigus, aiding in its diagnosis and in the prevention of future flare-ups.

Acute generalized exanthematous pustulosis: a retrospective analysis showing a clear predilection for women.

The clinical reaction pattern acute generalized exanthematous pustulosis is increasingly recognized today as drug intake details are more meticulously recorded and diagnostic guidelines are formulated. Nevertheless, the diagnosis and etiology remain unclear. This examination of the clinical and histologic features of acute generalized exanthematous pustulosis, undertaken in a retrospective study of 13 patients in an urban medical center, was aimed at determining the underlying mechanism of the etiology of the disease. Findings include a female predominance and the overwhelming prevalence of acetaminophen as the culprit agent, adding two more components to what is known about acute generalized exanthematous pustulosis. The possible mechanisms of the disease are discussed, enlightened by its appearance in two women in the study who were pregnant when the reaction first erupted.

A possible additional diagnostic tool for cutaneous melanoma.

The rise in incidence of malignant melanoma and the dismal prognosis of late detection emphasize the need for early detection and recognition of the disease. The well-known ABCD method for detection of melanoma has recently been revised by adding an "E" for changes in size, shape, color, crusting, itching, bleeding, and erythema. In an observational study, 8 of 14 (57%) melanoma patients exhibited a particular reddish hue to the skin adjacent to the melanoma, with no distinguishable borders. In another study, vascular endothelial growth factor was positive in biopsy specimens from 3 of 6 (50%) patients with erythema and in 4 of 7 (57%) patients without erythema. Platelet-derived growth factor was positive in all 6 (100%) of the patients with erythema and in 4 of the 7 (57%) without erythema. This erythema can help alert the clinician to the presence of malignant melanoma and serve as a prognostic factor or an indicator of the efficacy of treatment.
