[Erythema gyratum repens Gammel without internal cancer--case report].

Erythema gyratum repens Gammel is a rare illness that almost always accompanies the tumour of internal organs. The case of 63 year-old women with the clinical and histological recognition of Erythema gyratum repens Gammel without the accompanying tumour will be introduced. The exanthema had the character of swelling, itchy erythemas that very quickly (in a few days) started widening concentrically, forming the typical ring-shaped pattern reminding grains. Mucous membranes were free from changes. Laboratory and pictorial examination did not show any significant deviations. According to the histopathological examination the clinical recognition turned out to be true. During the hospitalization, in spite of treatment (steroids - medium dose, anti-histamine drugs and external steroids therapy) a progression of skin changes and appearance of some new single changes were observed. At present the patient is under constant ambulatory control in order to keep the exanthemas under intensive oncological alertness.
