Keloids and/or hypertrophic scars (ch/CH) are benign tumors, poorly understood and studied, yet with socio-economic impact for serious cases precisely to African black people in less developed countries. We wanted to evaluate their frequency and epidemiological and clinical aspects in secondary school in the city of Ouagadougou. Patients and methods: It was a descriptive cross-sectional study, from March 6 to April 22 2017, on secondary school students from the city of Ouagadougou. We used the
... ougou. We used the stage-three random sampling technique from the school population list from the city of Ouagadougou in 2016-2017. The sample minimal size was 904 according to Pascal Ardilly Formula. The sought variables were epidemiological, clinical and therapeutic. Variables on the impact and students' knowledges about ch/CH scars were also sought. Results: Out of 1225 examined students, we identified 125 ch/CH scars carriers, that's a frequency of 10,20%. There were 99 cases of keloids (79,2%), 26 cases of hypertrophic scars (20,8%) and no case of keloid diseases. Depending on the sex, there were 64 girls, and 61 boys. The average age was 18,10 years. 22,4% of the cases presented a family history for ch/CH scars. The traumatic etiology was found in 96% of the cases mostly with injuries made by sharp objects (48%), and public road accidents (28,3%). Therapeutic attitudes were abstention (78,4%), traditional treatment (18,4%) and modern treatment (3,2%). An aesthetic implant was found to 24 students including 17 girls. According to the student, ch/CH scar was a healing anomaly (484 students), a malformation (95) , a bewitchment (20), a type of cancer (2). Conclusion: Keloids/Hypertrophic scars frequency is high to school student in the city of Ouagadougou. The lack of medical care is probably linked to students' ignorance about possibilities of support.
