Area of Science:

  • Dermatology
  • Histopathology

Background:

  • Porokeratosis is a group of keratinization disorders.
  • Differentiating variants can be challenging.

Observation:

  • A 39-year-old woman presented with multiple keratotic papules on palms, soles, fingers, and toes.
  • Spiny plugs were noted on the toe edges.

Findings:

  • Histologic examination revealed a characteristic cornoid lamella.
  • This finding supports the diagnosis of punctate porokeratotic keratoderma.

Implications:

  • The term "punctate porokeratotic keratoderma" is proposed for this distinct clinical and histological presentation.
  • This clarifies nomenclature for related conditions like porokeratosis punctata palmaris et plantaris.
