Introduction: Keloid and hypertrophic scar are pathological scars resulting from excessive accumulation of collagen in wound healing process. Data about profiles of keloid and hypertrophic scar are rarely found in Indonesia. Therefore, it is necessary to conduct research related to keloid and hypertrophic scar. This study aimed to provide valuable data for further research.Methods: This was descriptive retrospective study evaluating 105 patients treated for keloid and hypertrophic scar from 2014 to 2017 using medical records of working-age patients.Results: Mostly in patients between 17-25 years old (40%). Comparison between male and female patients were 1.07:1 (keloid) and 1.09:1 (hypertrophic scar).
