    Bleomycin can cause inflammatory skin lesions that progress to linear hyperpigmentation. Unreported observations include streaking after a single dose and melanocyte vacuolar degeneration during inflammation.

    Area of Science:

    • Dermatology
    • Pathology

    Background:

    • Bleomycin is a chemotherapy agent with known cutaneous side effects.
    • Understanding the spectrum of bleomycin-induced skin reactions is crucial for patient management.

    Observation:

    • Two patients developed linear hyperpigmentations following bleomycin administration.
    • One patient exhibited streaking after a single 5 mg dose of bleomycin.
    • The other patient showed vacuolar degeneration of melanocytes during the inflammatory phase.

    Findings:

    • Bleomycin-induced inflammatory lesions can evolve into linear hyperpigmentations.
    • Development of streaking after a low, single bleomycin dose is a novel observation.
    • Vacuolar degeneration of melanocytes is a newly identified feature in bleomycin-induced inflammation.

    Implications:

    • These findings expand the known dermatological side effects of bleomycin.
    • Highlights the importance of monitoring for pigmentary changes post-bleomycin therapy.
    • Suggests a potential mechanism for bleomycin-induced hyperpigmentation involving melanocyte damage.
