Introduction: In Senegal, the studies on scalp tumors are almost non-existent. The purpose of our study was to determine the epidemiological and anatomoclinical features of scalp tumors in dermatology., Methods: We conducted a prospective descriptive and analytical study in both Department of Dermatology at Dakar over a period of 16 months (01 March 2014-30 June 2015). Histopathological examination was used to confirm the diagnosis., Results: We collected data from the medical records of 36 patients, of whom 14 had malignant tumors and 22 benign tumors. Sex ratio was 1.1, the average age of patients with malignant tumors was 51 years while the average age of patients with benign tumors was 39 years. Hospitalization rate was 0.18%. The average time of consultation in patients with malignant tumors was 14 months, while in patients with benign tumors was 52 months. In 11 patients with malignant tumors, first treatment was based on traditional therapy. Malignant tumors included: squamous cell carcinoma (n=8), basal-cell carcinoma (n=3), lymphoma, hidradenocarcinoma and Darier-Ferrand dermatofibrosarcoma (one case for each type). Benign tumors included: botriomycoma (n=5), trichilemmal cyst, sebaceous hamartoma, cylindroma and lipoma (2 cases for each type), heloid, syringocystadenoma papilliferum, schwannoma, neurofibroma and nevus (one case for each type). Tumor malignancy was associated to ulcero-budding appearance (p=0.003), diameter >4 cm (p=0.05), pain (p=0.009) and bleeding (p= 0.006)., Conclusion: Scalp tumors in black people are usually benign. Squamous cell carcinoma is the most common malignant form., Competing Interests: Les auteurs ne déclarent aucun conflit d’intérêts., (© Assane Diop et al.)

Clinical features and auto-antibodies profile of 35 Senegalese patients' diagnosed systemic lupus erythematosus (SLE) were analyzed after measurement of antinuclear antibodies (ANA) by IFI, detection of Abs anti-DNA native by ELISA and evaluation of antibodies anti-Sm, anti-RNP, anti-SSA anti-SSB, anti-CCP2, anti-J0, and anti-Scl70 levels by immunodot. Mean age of 33 yrs (18-50 yrs) and sex ratio (F/M) of 16 were found. The most frequent clinical features were rheumatic (88.7%) and cutaneous (79.4%) disorders. ANA and anti-DNAn Abs were detected in 85.7% and 62.5% of the patients respectively. Abs anti-RNP, anti-Sm, anti-SSA, anti-SSB and anti-CCP2 were detected in 30 to 70% of patients. In young patients, the levels of anti-DNAn and anti-Sm Abs were higher than in patients older than 40 yrs (P<0.05). In addition, associations of cutaneous and rheumatic symptoms were characterized by high levels of anti-DNAn, anti-SSA and anti-SSB Abs. Our study shows the interest of a measurement of anti-DNAn, anti-SSA and anti-SSB Abs during the follow of SLE patients particularly in those presenting both rheumatic and cutaneous symptoms.

Introduction: There is a lack of data on endemic Kaposi's sarcoma in sub-Saharan Africa. The goal of this study was to clarify its epidemiological, clinical and therapeutic aspects in that region., Patients and Methods: A 7-years retrospective study, including all patients with endemic Kaposi's disease diagnosis was carried out., Results: We identified 29 cases of endemic Kaposi's representing 1.2% of total hospitalizations and an incidence of 4.4. The mean age and the sex ratio were 63.2 years 2.22 respectively. The average delayed time to seek for medical care was 6.75 months. Cutaneous manifestations were dominated by angiomatous papulonodular lesions in 15 cases (51.72%) ulcerated lesions in 8 cases (27.58%), lymphedema in 5 cases (17.24%), a sarcomatous degeneration in 2 cases and verrucous papules in one case. Mucosal involvement was observed in 7 cases (24.13%). The extracutaneous lesions were noted in 18 cases, with 6 cases of bone, 5 cases of lymph nodes, 5 cases of gastrointestinal and 2 cases of lung involvement. The outcome was favorable for single-agent chemotherapy with bleomycin in more than half of the cases. Recurrences were observed in 2 patients, 2 cases were died and 7 cases never came back., Conclusion: Endemic Kaposi's disease is more frequent in elderly people with a higher frequency of extracutaneous involvement and florid forms., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

The koranic schools are in poor socio-economical conditions in Dakar and skin diseases are common in these conditions. The goal of our descriptive study was to determine the prevalence of skin diseases occurring in these situations. One hundred five boys from four koranic schools of Dakar were examined. Eighty percent of the examined boys were with unless one skin disease. Tinea capitis (42.66%), scabiosis (13.33%), pyoderma (15.33%), plantar keratodermia (100%) were the skin diseases. In 34.52% these skin disease were associated and antecedents of skin infections diseases were reported in 89.5% of boys. Atopic dermatitis was in 2.38% cases, keloid in 1.19%. The other frequent diseases were abdominal parasitosis (71.42%), umbilical hernia (6.66%). All skin diseases were improved only in 50% of cases after two months of treatment. Tinea capitis was cured in 4 months after treatment. The high prevalence and the chronicity of the skin disease were due to poor socio-economical conditions.

Occupational dermatitis, mainly allergic contact dermatitis and skin irritations are increasing because of new allergens and diversity of the industrial procedures. In Senegal occupational contact dermatitis are currently observed and they are not declared at our social security institution. The aim of our trial was to determinate the frequency of occupational allergic contact dermatitis, the allergens responsible and the exposed occupations. We included in a one year lasting prospective trial, all patients with occupational contact dermatitis confirmed by positive cutaneous allergological tests. Among 201 cases of contact dermatitis, 27 (12,91%) were included and predominant occupational sectors were building, mechanics, health, cleaning and trade. Main responsible allergens were dichromate of potassium (7), N-isopropyl N-phenylparaphenylenediamine (3), fragrance mix (3), thiuram mix (3), colophane (3), formaldehyde (2), nickel sulphate (2), Chalk (2). Building sector was the most frequent source because of high use of dichromate of potassium in cement and formaldehyde in painting-glue. In mechanics, N-isopropyl N-phenylparaphenylenediamine is present in rubbers and fragrance mix in oils. Occupational dermatitis in health workers are due to presence of thiuram mix in the gloves, and dichromate of potassium found in antiseptics. To decrease the incidence of occupational contact dermatitis in our country, we have to promote prevention among workers by using individual protective outfits and increasing workers medical survey and information about risks and means of prevention.
