Abstract

Insights

Acquired perforating dermatosis (APD) often links to systemic diseases like diabetes. Further patient evaluation is recommended for associated conditions.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Acquired perforating dermatosis (APD) is characterized by transepidermal elimination of dermal materials.
  • It encompasses Kyrle's disease, perforating folliculitis, elastosis perforans serpiginosa, and reactive perforating collagenosis.
  • APD frequently co-occurs with systemic conditions, notably diabetes mellitus and chronic renal failure.

Purpose of the Study:

  • To analyze the clinical and histopathologic features of 30 APD cases.
  • To investigate the association between APD and systemic diseases.

Main Methods:

  • Retrospective review of medical records and biopsy specimens from 30 diagnosed APD patients.

Main Results:

  • The average patient age was 55.5 years, with lesions lasting 7.8 months.
  • Lower extremities were the most affected sites (73.3%).
  • A significant majority (83.3%) experienced pruritus, and 63.3% had at least one systemic disease, primarily diabetes mellitus (56.7%) and chronic renal failure (33.3%). Reactive perforating collagenosis was the most common histopathologic type (73.3%).

Conclusions:

  • Most APD cases are linked to systemic diseases.
  • Comprehensive patient evaluation, including medical history, clinical examination, and diagnostic testing, is crucial for identifying associated systemic conditions.
