Area of Science:

  • Dermatology
  • Histopathology

Background:

  • Porokeratosis is a rare genodermatosis characterized by abnormal keratinization.
  • Typical presentations include verrucous papules or plaques with a central depression and a raised, keratotic border.

Observation:

  • A 63-year-old man presented with linear, annular, and acuminate skin lesions.
  • Histological examination confirmed the features of porokeratosis.
  • The lesions exhibited a unique pattern of spontaneous resolution, recurrence, and ulceration.

Findings:

  • The patient's porokeratosis demonstrated an unusual clinical course with repeated spontaneous clearing and subsequent recurrence.
  • The ulceration during recurrence represents a previously undocumented manifestation in porokeratosis.

Implications:

  • This case expands the known clinical spectrum of porokeratosis.
  • The described pattern suggests potential underlying immune or inflammatory mechanisms influencing lesion behavior.
  • Further research is warranted to understand the factors driving spontaneous resolution and recurrence in porokeratosis.
