We describe a 16-year-old boy with reflex sympathetic dystrophy after a fracture of the right hand. He had inflammation of the proximal nail folds and arrested nail growth of digits 3, 4 and 5 on the right hand. After 2 months lymphatic drainage treatment, the changes of the nails had disappeared.
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.
