This study identifies secondary membranous lipodystrophy in skin diseases like morphea profunda. It proposes a classification for this fat necrosis occurring due to other conditions.

Area of Science:

  • Dermatopathology
  • Histology

Background:

  • Observed unusual fat necrosis in patients with diverse skin conditions.
  • Fat necrosis can manifest in various dermatological diseases.

Purpose of the Study:

  • To classify membranous lipodystrophy.
  • To integrate findings from new cases and literature reviews.

Main Methods:

  • Analyzed clinical and histopathologic features of five skin disease cases with membranous lipodystrophy.
  • Conducted a review of previously published similar findings.

Main Results:

  • Identified membranous lipodystrophic changes in morphea profunda, lupus panniculitis, and factitial ulcer.
  • Characterized microcysts formed from destroyed fat cells and eosinophilic, amorphous linings.

  • Detected microgranules in histiocytes and hyalinized collagen, with positive Periodic acid-Schiff and Sudan black B staining.

    • Conclusions:

    • Proposed 'secondary membranous lipodystrophy' for localized changes resulting from skin diseases.
    • Differentiated secondary form from primary idiopathic membranous lipodystrophy.
    • Established a classification for localized subcutaneous fat necrosis associated with dermatological conditions.
