[Wells syndrome mimicking facial cellulitis: Three cases]. / Syndrome de Wells mimant une cellulite infectieuse de la face : trois observations.

BACKGROUND: Wells syndrome, or eosinophilic cellulitis, is an uncommon inflammatory dermatosis of unknown etiology that is characterized by clinical features of pruritic cellulitis-like plaques on the extremities and a histological picture of eosinophilic infiltrate of the dermis with "flame figures". PATIENTS AND METHODS: Herein, we report three cases of idiopathic Wells syndrome masquerading as bacterial facial cellulitis. Under treatment with oral prednisone and/or combined therapy with levocetirizine and hydroxyzine, all patients showed a dramatic improvement of their skin lesions. DISCUSSION: These cases highlight the need to consider Wells syndrome in the differential diagnosis when evaluating a patient with facial cellulitis that does not respond to an initial antimicrobial regimen. In addition, our cases suggest that combined therapy with levocetirizine and hydroxyzine may be successfully used as first-line therapy or to prevent relapse after discontinuation of corticosteroid treatment.

[Meningococcemia without meningitis: A report of two cases]. / Méningococcémie sans méningite: à propos de deux observations.

INTRODUCTION: Meningococcemia without meningitis is an often under recognized clinical form of invasive Neisseria meningitidis infection. CASE REPORTS: We report two unusual cases of invasive meningococcal disease who presented with meningococcemia without distinct signs of meningitis or severe sepsis manifestation. In both cases, confirmation of the diagnosis is provided by meningococcal PCR performed on blood or skin lesion biopsy. CONCLUSION: Clinical recognition of this entity is crucial for early antibiotic treatment and to avoid delayed diagnosis and potentially dangerous complications.

[Disulone and hepatosiderosis]. / Disulone et hépatosidérose.

BACKGROUND: Disulone (dapsone + iron oxalate) is a sulfone used in the treatment of numerous skin diseases. We report two cases of hepatosiderosis secondary to long-term administration of Disulone. PATIENTS AND METHODS: Case n degrees 1. A 51-year-old man was treated with Disulone for a neutrophilic skin disease. After 17 years of treatment, elevated serum ferritin and free iron with hemolysis were found. Liver biopsy confirmed hepatosiderosis. A diagnosis of genetic hemochromatosis was ruled out by the absence of C282Y mutation of the HFE gene. Case n degrees 2. A 52-year-old man receiving Disulone for dermatitis herpetiformis for 25 years presented elevated serum ferritin and free iron with hemolysis. Hepatic iron overload was confirmed by liver biopsy. The absence of C282Y mutation (HFE gene) ruled out a diagnosis of genetic hemochromatosis. DISCUSSION: In our two cases, hepatosiderosis was noted after long-term administration of Disulone. This complication has been reported only rarely. In murine models, a relationship was found between prolonged administration of dapsone and hepatic iron overload as revealed by hemolysis. Although it is difficult to extrapolate this relationship to humans with any certainty, our patients had also chronic hemolysis and iron overload secondary to administration of Disulone. Moreover in France, dapsone is marketed in combination with iron oxalate, with the attendant risk of iron overload. These cases raise the question of the need for serum ferritin analysis during Disulone therapy.
