title: Precipitating factors and associated diseases in 84 patients with granuloma annulare: a retrospective study.
abstract: In a retrospective study including 84 patients, we assessed precipitating factors of granuloma annulare (GA) and associated pathologies. Fifteen per-cent of the patients reported stress as an important trigger of GA, and in 10 patients (12%) we found an association between GA and diabetes mellitus: 3 latent, 4 type I and 3 type II. Eight of the diabetic patients presented multiple and 5 generalized GA. They suffered significantly more often from chronic relapsing GA than nondiabetic patients.
