    Area of Science:

    • Dermatology
    • Pharmacology

    Background:

    • Minocycline hydrochloride is a widely used antibiotic with known, though infrequent, associations with localized pigmentary changes in various tissues.
    • Previous reports have documented pigment deposition in skin, bones, teeth, and thyroid, often localized.

    Observation:

    • This report details a case of a woman treated with minocycline (Minocin) for acne vulgaris.
    • The patient developed a distinct, generalized, cutaneous, dark blue-gray hyperpigmentation during the course of treatment.

    Findings:

    • The observed generalized hyperpigmentation is attributed to minocycline therapy.
    • This represents a notable instance of a more widespread cutaneous side effect compared to previously reported localized pigmentary changes.

    Implications:

    • Clinicians should be aware of the potential for generalized hyperpigmentation as a side effect of minocycline treatment.
    • This finding expands the spectrum of known cutaneous adverse reactions to minocycline, emphasizing the need for vigilant monitoring in patients undergoing long-term therapy.
