Pseudoainhum associated with plica neuropathica

M R Diestelmeier, O G Rodman

    Cutis
    |December 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Mechanical factors rarely cause pseudoainhum in adults. Continuous hair manipulation led to a constricting hair band and plica neuropathica, resulting in near finger amputation.

    Area of Science:

    • Dermatology
    • Trichology

    Background:

    • Pseudoainhum is a rare condition characterized by constrictions of digits.
    • Mechanical factors are an uncommon cause of pseudoainhum in adults.

    Observation:

    • A case study of an adult patient presenting with self-induced digital constriction.
    • The patient exhibited continuous manipulation of their hair.

    Findings:

    • The continuous hair manipulation resulted in a constricting band of hair around a digit.
    • The patient also developed plica neuropathica, an unusual hair formation.
    • The digital constriction led to a near-amputation of the finger.

    Implications:

    • Highlights the potential for self-inflicted mechanical trauma to cause severe digital deformities.

  • Underscores the importance of identifying and addressing repetitive behaviors that can lead to physical harm.
  • Suggests that pseudoainhum, though uncommon, can arise from unusual and persistent mechanical stimuli.
