Introduction: Neonatal lupus erythematosus is a rare syndrome (affecting 5% of the children born of mothers with lupus), characterized essentially by cutaneous lesions and/or congenital auricular-ventricular heart block. It is due to the transplacental passage of maternal antibodies (anti-SSA or anti-SSB, or occasionally anti-U1RNP antibodies) into the fetal circulation., Observation: We report a case of neonatal lupus erythematosus, having appeared 4 weeks after birth. The 26 years old mother exhibited systemic lupus erythematosus concomitant to Gougerot-Sjögren's syndrome, with positive antinuclear factors (1/2560), native anti-DNA, anti-SSA and anti-SSB antibodies and anticardiolipin antibodies. During pregnancy, the mother had been treated with aspirin at the dose of 100 mg/day, followed by subcutaneous enoxaparin 0.4 ml/day, and combined with prednisone 10 mg/d and hydroxychloroquine 400 mg/day. Early and regular cardiac monitoring of the foetus was performed. The clinical examination and the electrocardiogram at birth were normal. Four weeks later, the infant presented with erythematous cutaneous lesions with atrophic center. No systemic treatment was initiated and the lesions partially regressed., Conclusion: Cutaneous lesions can also appear after the 4th week of life. It is important that the pediatricians clinically monitor all the children born to mothers exhibiting anti-SSA or anti-SSB antibodies, at least during the first 7 months of life.

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.
