Histopathology·2006

Two unique skin lesions resembling comedones were identified. These "hair cortex comedones" represent a peculiar variant of the dilated pore of Winer, offering new insights into follicular abnormalities.

Area of Science:

  • Dermatopathology
  • Histology
  • Clinical Dermatology

Background:

  • Comedones are a hallmark of acne vulgaris.
  • Dilated pore of Winer is a distinct benign follicular lesion.
  • Understanding follicular abnormalities is crucial for diagnosing skin conditions.

Observation:

  • Two cases presented with firm, black papules clinically mimicking comedones.
  • Histopathological examination revealed dilated hair follicles.
  • Abnormalities of the hair cortex were noted within the lesions.

Findings:

  • The observed lesions are histopathologically distinct.
  • Findings suggest a unique variant of the dilated pore of Winer.
  • The term "hair cortex comedo" is proposed for these lesions.

Implications:

  • This finding expands the spectrum of follicular nevi.
  • "Hair cortex comedo" may aid in precise diagnosis and classification.
  • Further research is warranted to understand the pathogenesis and clinical behavior.
