Summary

This study found that melasma in men presents with similar clinical and histological features to women. Key factors include sun exposure and family history, with hormonal influence appearing minimal.

Area of Science:

  • Dermatology
  • Dermatopathology
  • Medical Research

Background:

  • Melasma is a common facial hyperpigmentation condition, predominantly affecting women.
  • Previous research has primarily focused on melasma in female populations.
  • Understanding melasma in men is crucial for comprehensive dermatological insight.

Purpose of the Study:

  • To clinically and histologically evaluate melasma characteristics in a cohort of men.
  • To compare the clinicohistologic features of melasma in men with existing literature.
  • To identify significant etiological factors contributing to melasma in males.

Main Methods:

  • Clinical evaluation of 27 men diagnosed with melasma.
  • Histological analysis of affected skin.

  • Wood's light examination to determine melasma type (epidermal, dermal, mixed).

    • Main Results:

    • Identified three localization patterns: centrofacial, malar, and mandibular.
    • Histological analysis revealed epidermal and/or dermal hyperpigmentation.
    • Significant etiological factors identified were sun exposure (66.6%) and familial predisposition (70.4%).

    Conclusions:

    • Melasma in men exhibits clinicohistologic characteristics comparable to those observed in women.
    • Sun exposure and genetic predisposition are significant contributing factors in male melasma.
    • Hormonal factors do not appear to play a significant role in the development of melasma in men.
