Abstract

BACKGROUND: Keloid is a form of wound healing that results from fibrous tissue activity. It can develop beyond the boundaries of the original wound, extends into the dermis layer, and disrupting the appearance. Previously, no studies have revealed a correlation between melanin pigment and keloid. AIM: This research aimed to describe the correlation between melanin concentration and collagen deposition in keloid tissue. MATERIALS AND METHODS: A prospective study conducted through the application of a cross-sectional analytic survey method. The color of the skin was measured using a chromameter, and a histopathologic examination was performed on the skin surrounding the keloid, as well as the keloid tissue. Data were analyzed using a t-test, correlation, and linear regression statistics. RESULTS: The results showed a significant difference between melanin concentration and collagen deposition in the skin surrounding the keloid tissue. No significant difference was observed between melanin concentration in the surrounding skin of keloid and those in the keloid tissue, as well as collagen deposition. Meanwhile, the melanin concentration in the surrounding skin of keloid and keloid tissue had a significant relationship with fibrocytes number. CONCLUSION: There is a significant correlation between melanin concentrations and collagen density in the keloid tissue.
