Abstract
BACKGROUND: Conflicting reports have been published regarding whether a relationship exists between granuloma annulare (GA) and diabetes mellitus (DM). OBJECTIVES: To evaluate the prevalence of DM in patients with GA using a case-control design. METHODS: The incidence of DM was determined in 126 patients with GA. Fifty of the 126 patients with GA were further compared with an age-, sex- and race-matched population of psoriasis patients seen during a similar time period in the same clinical setting. RESULTS: Eleven (9%) of 126 GA patients suffered from type 2 DM. In the matched comparison of 50 patients, 11 (22%) GA patients and 10 (20%) psoriasis patients suffered from type 2 DM. CONCLUSIONS: This case-control study failed to reveal any statistically significant correlation between GA and type 2 DM.
