Gingival pigmentation associated with antimalarial drugs

A Manor, I Sperling, A Buchner

    Summary

    Oral administration of Camoquin, an antimalarial drug, can cause bluish pigmentation in the gums and other oral tissues. This drug-induced pigmentation is reversible and fades after discontinuing the medication.

    Area of Science:

    • Oral Medicine
    • Dermatology
    • Pharmacology

    Background:

    • Antimalarial drugs are increasingly used for dermatologic conditions.
    • Oral side effects of medications require careful consideration in clinical practice.

    Observation:

    • Two cases presented with bluish pigmentation of the gingivae and other oral mucosal sites.
    • The pigmentation was directly linked to the oral administration of the antimalarial drug Camoquin.

    Findings:

    • The exact nature of the pigment (e.g., hemosiderin vs. melanin) and its pathogenic mechanism remain debated.
    • Evidence suggests increased melanin formation may be responsible for the observed pigmentary changes.
    • Pigmentation gradually resolves upon cessation of Camoquin therapy.

    Implications:

    • These findings highlight the importance of recognizing drug-induced oral pigmentation in differential diagnosis.
    • Increased use of antimalarials in dermatology necessitates awareness of potential oral side effects.
    • Oral pigmentary changes serve as a clinical indicator of systemic medication effects.
