Pili torti involves hair shaft flattening and twisting, leading to disruptions and knots. These structural abnormalities originate within the hair follicle

Area of Science:

  • Dermatology
  • Genetics
  • Cell Biology

Background:

  • Pili torti is a rare hair shaft abnormality characterized by flattened and twisted hairs.
  • Understanding the underlying mechanism is crucial for diagnosis and potential treatments.

Observation:

  • Hair samples from a patient with classical pili torti were analyzed using light microscopy, SEM, TEM, and 3-D analysis.
  • Key observations included flattened hair shafts, twisting, knotting, and longitudinal ruptures.

Findings:

  • Abnormalities in the outer root sheath (ORS) and inner root sheath (IRS) thickness and cell arrangement were noted.
  • Hair twisting was evident within the hair follicle at the middle levels.
  • Structural disruptions were observed at various points along the hair shaft, including flattened regions and knots.

Implications:

  • This study elucidates the hair follicle's role in pili torti pathogenesis.
  • Findings provide insights into the cellular and structural basis of this hair disorder.
  • Further research can explore genetic and molecular factors contributing to these follicular abnormalities.
