[Eosinophilic cellulitis--clinical and histological aspects].

Eosinophilic cellulitis (Wells' syndrome) is a rare skin disease whose aetiology is still unknown. The onset is acute, and different disease stages may exist simultaneously during the course. Histological examination shows flame figures as a characteristic, but not pathognomonic, feature. In later stages the infiltrate adopts granulomatous characteristics. Malignant haematological disorders, which frequently occur with this disease, should be excluded.
