Minocycline exhibits yellow-green fluorescence, detectable in various skin hyperpigmentation types beyond type 1. This finding suggests minocycline can act as a fluorescent probe for diagnosing diverse minocycline-induced cutaneous hyperpigmentation.

Area of Science:

  • Dermatology
  • Pharmacology
  • Medical Imaging

Background:

  • Minocycline, an antibiotic, possesses intrinsic yellow-green fluorescence.
  • This fluorescence was previously documented exclusively in type 1 minocycline-induced skin hyperpigmentation.

Observation:

  • This study explored minocycline fluorescence in other hyperpigmentation types.
  • Confocal Laser Scanning Microscopy (CLSM) and light microscopy were used on skin biopsies from three patients.

Findings:

  • Yellow-green fluorescence was detected in hyperpigmented skin of patients with type 2 and type 4 minocycline-induced cutaneous hyperpigmentation.
  • No fluorescence was observed in non-pigmented skin samples.

Implications:

  • Minocycline's fluorescence is not limited to type 1 hyperpigmentation.

  • Minocycline may serve as a diagnostic fluorescent probe for all forms of minocycline-induced cutaneous hyperpigmentation.
