Pyodermitis of genital areas: an atypical manifestation of eosinophilic pustulosis of childhood.

Eosinophilic pustulosis of the scalp was first described in 1984. It has also been described in other sites than the scalp. We report a case in which the lesions exclusively involved the genitals.

[Methi-resistant Staphylococcus aureus myositis].

Introduction: Pyomyositis are relatively rare in our countries.

Case Report: A 73-year-old-man presented with leg pains and septicemia. Diagnosis of pyomyositis was made and a large incision was performed after which the patient had a progressive improvement.

[Self-induced cutaneous lesions in Prader-Willi syndrome].

Introduction: The Prader-Labhart-Willi syndrome was first described in 1956. Prader-Labhart-Willi syndrome is the most common genetic form of human obesity and the incidence of Prader-Labhart-Willi syndrome has been estimated to 1 in 10,000 or 25,000 live births. Skin-picking was frequently reported in Prader-Labhart-Willi syndrome and two patients who displayed repetitive skin picking are described.

[Familial erythermalgia treated with pizotifen].

Introduction: Primary erythermalgia is a rare acrosyndrome due to paroxystic arteriolar dilatation of extremities that become red and congested with warmth and burning sensation or pain.

Observation: We report herein the observation of a primary erythermalgia affecting 3 degrees in the same family (grandfather, uncle/mother, and children with early onset at 6 years): pizotifene, an antiserotoninergic drug proved to be effective in mother and 14-year-old child who had never drawn benefit from any previous treatment.

Discussion: Several etiologies may be responsible for erythermalgia according to the clinical type: primary erythermalgia with pediatric onset, and secondary erythermalgia as a reaction to myeloproliferation, other diseases, drug or heavy metal poisoning.
