    Area of Science:

    • Dermatology
    • Pathology
    • Fibroproliferative Disorders

    Background:

    • Keloids are benign fibrous tumors developing at injury sites.
    • They commonly affect individuals aged 10-30, often on the upper back, shoulders, earlobes, and chest.
    • The precise etiology of keloid formation remains unclear.

    Purpose of the Study:

    • To summarize the characteristics of keloids.
    • To discuss the cellular and molecular basis of keloid formation.
    • To review current treatment modalities and their efficacy.

    Main Methods:

    • Review of existing literature on keloid pathophysiology and treatment.
    • Analysis of fibroblast behavior in keloid tissue.
    • Compilation of data on various therapeutic interventions.

    Main Results:

    • Keloids exhibit increased cellularity and metabolic activity in fibroblasts.
    • Keloid fibroblasts show enhanced synthesis of collagen and proteoglycans.
    • Numerous treatments, including corticosteroids, surgery, and radiation, have shown variable success.

    Conclusions:

    • Keloids are characterized by excessive fibrous tissue deposition due to fibroblast activity.
    • Understanding keloid fibroblast behavior is crucial for developing effective therapies.
    • Further research is needed to establish optimal and consistent treatment strategies for keloids.
