Area of Science:

  • Dermatology
  • Histopathology
  • Microscopy

Background:

  • Hair casts are an uncommon finding, with only 31 cases documented since 1897.
  • This study presents a new case in an 8-year-old girl, adding to the limited literature.

Observation:

  • The case involved an 8-year-old girl presenting with hair casts.
  • Detailed examination utilized both light and electron microscopy (transmission and scanning).

Findings:

  • Microscopic analysis revealed the characteristic lesion of hair casts.
  • The lesion comprises two concentric layers of keratinized cells.
  • These layers exhibit differing structures, analogous to Huxley's and Henle's layers of the hair follicle sheath.

Implications:

  • This detailed microscopic description contributes to understanding the histopathology of hair casts.
  • Further research may elucidate the specific mechanisms and causes of this rare condition.
  • Accurate diagnosis and understanding of hair cast morphology are crucial for clinical evaluation.
