[Syndrome of the ingrown nails?].

Among the 20 patients with ingrowing toenails operated on in the Department of Dermatoloy in Cologne in 1976, we noticed a combination of the following signs: ingrowing big toenail, latent diabetes, tall stature, pseudo-acromegaly, hyperhidrosis and a preponderance of the male sex and of the age group 12-16 years. Our findings indicate that all patients with ingrowing toenails should be examined for latent diabetes, and that ingrowing toenails are mainly to be found in young male patients with a particular type of constitution.
