    Area of Science:

    • Dermatology
    • Pathology
    • Trichology

    Background:

    • Peripilar hair casts are a rare finding in dermatological literature.
    • Their prevalence may be underestimated in clinical practice.

    Observation:

    • Two patients presented with fine, whitish nodular accretions surrounding hair shafts on the scalp.
    • These casts measured 3-7 mm and were mobile along the hair shaft.

    Findings:

    • The accretions consisted of epithelial cells and keratinous debris.
    • The location varied along the hair shaft, not exclusively at the follicular opening.

    Implications:

    • Identifies potential causative factors for peripilar hair casts, including mechanical traction from hair styling.
    • Suggests a link between hair loss anxiety, trichotillomania, and the development of these casts.
    • Highlights the need for increased clinical awareness of this condition.
