Changing trends and allergens in the patch test standard series: a mayo clinic 5-year retrospective review, january 1, 2001, through december 31, 2005.

Objective: To present and interpret results of patch testing with the Mayo Clinic standard series over 5 years.

Design: Retrospective study. A standardized patch testing technique was used.

Patch test results from the Mayo Clinic Contact Dermatitis Group, 1998-2000.

Background: Patch testing is a diagnostic tool for the evaluation of patients with suspected allergic contact dermatitis. A standard series of allergens similar to that used by the North American Contact Dermatitis Group (NACDG) is used at Mayo Clinic.

Objective: Our aim was to report the results of patch testing with a standard series at Mayo Clinic from July 1, 1998, to Dec 31, 2000 and to compare our findings with those of the NACDG during the same period.

Granuloma annulare presenting as contact dermatitis.

Granuloma annulare is a benign idiopathic disorder of the dermis that has various clinical presentations and an unknown etiology. We discuss a patient who presented with a contact dermatitis that demonstrated granuloma annulare on biopsy. The most likely etiologic agent was a substance known as FAZ (an exhaust product of Kodak DryView laser imaging film), to which the patient was exposed in his occupation.
