Panorama des dermatoses tumorales vues en consultation dermatologique au Centre National Hospitalier Universitaire Hubert Koutoukou Maga de Cotonou au Bénin / Overview of tumoral dermatoses seen in dermatological consultation at the National University Hospital Center Hubert Koutoukou Maga in Cotonou, Benin

Introduction Les dermatoses tumorales sont des néoformations tissulaires dues à une prolifération cellulaire excessive, anormale, anarchique et plus ou moins autonome, aux dépens de la peau et de ses annexes. Ces dermatoses tumorales peuvent être bénignes, malignes ou à malignité limitée. L'objectif de la présente étude est de répertorier l'ensemble des dermatoses tumorales vues en consultation dermatologique au CNHU-HKM de Cotonou. Patients et méthodes Etude transversale rétrospective et descriptive ayant porté sur les dossiers des patients vus pour des tumeurs cutanéo-muqueuses, dans le service de Dermatologie-vénérologie du Centre National Hospitalier Universitaire Hubert Koutoukou Maga (CNHU-HKM) de Cotonou, de 2009 à 2023. Les données épidémiologiques et cliniques ont été recueillies à partir des registres de consultations puis saisies et analysées avec les logiciels Excel, EPI-DATA et SPSS. Résultats Au total, 15627 nouveaux patients ont été enregistrés, dont 1221 atteints de dermatoses tumorales (7,81%). L'âge moyen était de 33 ans ± 18,71 ; la tranche d'âge la plus représentée était celle de 20 à 39 ans (46,30%). La sex-ratio était de 1,08. Les lésions étaient acquises chez 93,94% des patients. Trente-cinq types de dermatoses tumorales ont été colligés. Les tumeurs bénignes représentaient 95,43% des patients. Elles étaient dominées par les chéloïdes (25,34 %) suivies parles condylomes (17,50 %), les verrues (10,12%), le molluscum contagiosum (7,54 %), l'ensemble formé par les nævi et hamartomes (5,18 %) et les kystes sébacés (4,57 %). Les tumeurs malignes étaient rares et représentées par les carcinomes spinocellulaires (1,14%), basocellulaires (0,30%) et les mélanomes (0,30%). Les tumeurs à malignité limitée sont essentiellement représentées par la maladie de Kaposi retrouvée chez 2,05% des patients. Conclusion Les dermatoses tumorales sont relativement fréquentes en milieu hospitalier au Bénin. Elles sont dominées par les tumeurs bénignes avec à leur tête les chéloïdes et les condylomes

Introduction Tumoral dermatoses are tissue neoformations resulting from excessive, abnormal, anarchic, and somewhat autonomous cell proliferation, affecting the skin and its annexes. These tumoral dermatoses can be benign, malignant, or of limited malignancy. The aim of this study is to catalog all the tumoral dermatoses seen in dermatological consultation at NUHC- HKM in Cotonou. Patients and Methods This was a retrospective, descriptive cross-sectional study based on the files of patients seen for cutaneous or mucosal tumors in the Dermatology-Venereology department of the National University Hospital Center Hubert Koutoukou Maga (NUHC-HKM) in Cotonou, from 2009 to 2023. Epidemiological and clinical data were collected from consultation registers and analyzed using Excel, EPI-DATA, and SPSS software. A total of 15,627 new patients were registered, of which 1,221 were affected by tumoral dermatoses (7.81%). The average age was 33 years ± 18.71; the most represented age group was 20 to 39 years (46.30%). The sex ratio was 1.08. Thirty-five types of tumoral dermatoses were collected. The lesions were non congenital in 93.94% of patients. Benign tumors accounted for 95.43% of the patients. They were dominated by keloids (25.34%) followed by condylomas (17.50%), warts (10.12%), molluscum contagiosum (7.54%), the group formed by nevi and hamartomas (5.18%), and sebaceous cysts (4.57%). Malignant tumors were rare and represented by squamous cell carcinomas (1.14%), basal cell carcinomas (0.30%), and melanomas (0.30%). Tumors with limited malignancy were primarily represented by Kaposi's disease found in 2.05% of patients. Conclusion Tumoral dermatoses are relatively frequent in the hospital setting in Benin. They are dominated by benign tumors, headed by keloids and condylomas

The Prevalence of Trachomatous Trichiasis in People Aged 15 Years and Over in Six Evaluation Units of Gaoual, Labé, Dalaba and Beyla Districts, Guinea.

PURPOSE: Trachoma is a public health problem in 42 countries. Inflammation associated with repeated ocular infection with Chlamydia trachomatis can cause the eyelid to scar and turn inwards, resulting in the eyelashes rubbing against the eyeball, known as trachomatous trichiasis (TT). In Guinea, baseline surveys conducted in 2013 reported inflammatory trachoma prevalences below the World Health Organization (WHO) threshold for elimination, but TT prevalences above threshold. Given this epidemiological context and time since baseline survey, TT-only surveys were conducted in selected districts to determine current TT prevalence. The results of this study provide critical data for assessing Guinea's achievement of trachoma elimination targets. METHODS: Four health districts, consisting of six evaluation units (EU), were surveyed. In each EU, field teams visited 29 clusters with a minimum 30 households included in each. Participants aged≥15 years were examined by certified graders trained to identify TT and determine whether management had been offered. RESULTS: A total of 22,476 people were examined, with 48 TT cases across the six EUs identified. Five of six EUs had an age-and-gender adjusted TT-prevalence unknown to the health system less than 0.2%, whereas one EU, Beyla 2, had an adjusted TT prevalence of 0.24%. CONCLUSION: These TT-only surveys, along with findings from other trachoma interventions, suggest that Guinea is close to achieving elimination of trachoma as a public health problem. This study demonstrates the value of undertaking TT-only surveys in settings where baseline surveys indicated active trachoma prevalences below WHO elimination threshold, but TT prevalences above it.
