title: [Wells' syndrome or eosinophilic cellulitis. Apropos of 2 cases. Review of the literature].
abstract: In 1971, four cases of a new dermatosis were described by Wells, under the name of recurrent granulomatous dermatitis with eosinophilia. In 1978, eight additional cases were reported by Wells and Smith and three authors suggested a shorter title: eosinophilic cellulitis for this syndrome. Since then, four additional cases were published in the literature. We report here two additional cases. From these eighteen upto now published cases, there is no doubt that this dermatosis, as initially described by Wells, is a distinct entity. Clinical course is characterized by sudden eruption of large infiltrated, itchy and/or painful plaques. Blisters are often associated. During the two or three weeks following the initial rash, the inflammatory aspect disappears. Lesions become indurated, and may resemble morphea. Spontaneous resolution occurs after about six weeks. Recurrences are constantly observed. Histologic features are a striking eosinophilic infiltrate associated with eosinophilic deposits constituting flame figures. Blood eosinophilia is present in most cases. Etiology of this entity remains unknown.
