Introduction: Bart’s syndrome is an uncommon inherited congenital disorder associating congenital cutaneous aplasia of the extremities and inherited epidermolysis bullosa. Bilateral and symmetrical involvement of the limbs is exceptionally described on black skin. In most cases, the diagnosis is clinical; however, the management remains very difficult and the extended forms are a real therapeutic challenge. We report 2 cases of Bart’s syndrome observed in a sub-Saharan African country (Senegal, Dakar). Case Presentation: It was about 2 premature female and male newborns. On physical examination, the girl presented with a total absence of skin on the limbs, associated with cutaneous detachment of the trunk representing a detached and detachable skin surface of 46%; the boy underwent a total absence of skin of more than 50% of the skin surface. The diagnosis of Bart’s syndrome was set based on the typical clinical aspect. The blood count and CRP were normal for the girl whereas it revealed some disorders for the boy. The 2 newborns were urgently admitted to an incubator, and the intensive care was started with hyperhydration, anti-staphylococcal prophylaxis, and daily dermatological care with antiseptic baths and fatty dressings. Conclusion: Bart’s syndrome is an uncommon genodermatosis characterized by a clinical triad associating congenital cutaneous aplasia of the extremities, inherited epidermolysis bullosa suspected in the presence of bubbles, and areas of cutaneous fragility and nail deformity. All types of which can be associated with this syndrome. The easy clinical diagnosis but the difficult management encumber the vital prognosis of our cases.

INTRODUCTION : au Sénégal, les études portant sur les tumeurs du cuir chevelu sont quasi inexistantes. Notre objectif était de déterminer le profil épidémiologique et anatomo-clinique des tumeurs du cuir chevelu en dermatologie.Méthodes: il s'agit d'une étude prospective, descriptive et analytique, réalisée sur une période de 16 mois (01er mars 2014 au 30 juin 2015), effectuée aux deux services de dermatologie de Dakar. La confirmation diagnostique était histopathologique.Résultats: nous avions colligé 36 patients dont 14 cas de tumeurs malignes et 22 cas de tumeurs bénignes. Le sex ratio était de 1:1, et l'âge moyen de 51 ans pour les premières et 39 ans pour les dernières. La fréquence hospitalière était de 0,18%. Le délai moyen de consultation était de 14 mois pour les tumeurs malignes et 52 mois pour les formes bénignes. Dans 11 cas de tumeurs malignes, le traitement traditionnel était le premier recours. Les tumeurs malignes étaient: carcinome épidermoïde (n=8), carcinome basocellulaire (n=3), lymphome, hidradénocarcinome et dermatofibrosarcome de Darier Ferrand (un cas chacun). Les tumeurs bénignes étaient: botriomycome (n=5), kyste trichilemmal, hamartome sébacé, cylindrome et lipome (2 cas chacun), et chéloide, syringocystadénome papillifère, schwannome, neurofibrome et nævus (un cas chacun). La malignité de la tumeur était associée à l'aspect ulcéro-bourgeonnant (p=0.003), au diamètre 4cm (p=0.05), à la douleur (p=0.009) et au saignement (p=0.006).Conclusion: les tumeurs du cuir chevelu, sur peau noire, sont dominées par les formes bénignes. Le carcinome épidermoïde est la tumeur maligne prédominante.

Les auteurs rapportent l'observation d'une maladie périodique diagnostiquée à l'aide de placards érysipélatoïdes récidivants et persistants sous antibiothérapie. L'interrogatoire, les tests génétiques et l'évolution favorable sous colchicine ont permis d'asseoir le diagnostic.

Hundreds of new leprosy cases are still diagnosed in Dakar despite all the efforts in the struggle by the national program for elimination of leprosy by the Institute of Applied Leprosy in Dakar. The aim of our study was to evaluate the epidemiological, clinicopathological and outcome of new cases of leprosy. A prospective study was conducted over a period of one year listing all new cases of leprosy based on clinical diagnosis, bacteriology and histology. 73 new cases were recorded. The sex ratio was 1.5 and the mean age of 39.5 years. Children aged from 0 to 15 years old represented 12%. The clinical forms were rated in order of decreasing frequency Borderline 47.94%, 30.13% lepromatous lepromatous, indeterminate 8.21, borderline lepromatous 6.84, TT: 5.47%, 1.36 and neurological bb%. Neurological signs were enlarged nerve in 50 cases, a neurological deficit in 16 cases and a sensitive deficit in 16 cases. The complications were burns and ulcerations in 10 cases, a claw in 7 cases, a reversal reaction in 7 cases, erythema nodosum in 4 cases and neuritis in 8 cases. The number of new cases mutilated was 24.65%. The smear was positive in 42% and histology contribution in 91.37% of cases. Our study highlights the significant number of patients with multibacillary contagious, affected children, the high proportion of disability grade 2/OMS reflecting the delay in diagnosis. This delay is due to ignorance, to traditional treatments and low socio-economic status and lack of trained diagnostic teams in different areas apart from referral centres.
