title: Widespread cutaneous vascular papules associated with peripheral blood eosinophilia and prominent inguinal lymphadenopathy.
abstract: A new section entitled "Dermatology Grand Rounds at the NIH" appears this month. The idea behind it is to provide a unique look at instructive dermatologic cases being presented at the weekly Dermatology Branch Grand Rounds at the National Cancer Institute, National Institutes of Health (NIH), Bethesda, Maryland. Patients seen at the NIH Clinical Center (which includes the NIH inpatient wards and outpatient clinics) are indeed unusual. To be evaluated here, they must be referred by an outside physician and must be placed in a research protocol. In other words, by this criterion, all NIH patients are considered research subjects. The diseases studied at the NIH range from the common to the obscure. Similarly, the dermatologic manifestations of these diseases are equally as diverse. Thus the purpose of this new section is to share some of these fascinating cases with the dermatologic community at large, as well as to provide a glimpse of exciting translational research that has relevance to clinical dermatologists. The format will be simple. Cases will be presented as unknowns, including relevant results from the history, physical examination, and histopathologic analyses. This will be done to challenge the clinicopathologic skills of the readers; authors will make every attempt to make the color clinical and pathologic photographs of the highest quality possible to assist readers in making the correct diagnoses. The discussion will be brief, focusing on the key teaching points of each case. These teaching points will vary from cases to case, covering clinical and histologic information, treatment issues, and/or novel laboratory advances with clinical relevance. Authors will emphasize brevity and clarity in all subsections of the case report, which I hope will promote a good learning experience for dermatology residents and busy practitioners alike. This section will initially be published 4 times annually. Finally, because the section is new to the JAAD, I welcome comments and suggestions to improve the quality of the articles.-Andrew Blauvelt, MD Feature Editor
