Summary

Elastofibroma, a benign pseudotumor, affects elderly males more than females. Pre-elastofibroma changes are common, suggesting unknown factors beyond aging contribute to its development.

Area of Science:

  • Pathology
  • Dermatology
  • Gerontology

Background:

  • Elastofibroma is a rare, benign soft tissue tumor.
  • It typically occurs in the subscapular region of older individuals.
  • The exact etiology of elastofibroma remains unclear.

Purpose of the Study:

  • To describe biopsy findings in elastofibroma cases.
  • To investigate the prevalence and morphological changes of elastofibroma in autopsies.
  • To explore potential contributing factors to elastofibroma development.

Main Methods:

  • Case study of two biopsy-proven elastofibromas (unilateral and bilateral).
  • Retrospective autopsy study of 100 elderly individuals.
  • Histopathological examination for elastofibroma and pre-elastofibroma-like changes.

Main Results:

  • Elastofibroma was found in 13% of autopsies, predominantly in elderly males (16.9%) versus females (7.3%).
  • Pre-elastofibroma-like changes, characterized by degenerated elastic fibers, were present in 81% of autopsies.
  • Minor pre-elastofibroma changes were noted in males, while major changes were more prevalent in females.

Conclusions:

  • Elastofibroma development may involve unknown factors in addition to physiological aging.
  • Abnormal elastogenesis or degeneration are less likely primary causes.
  • The findings suggest a complex interplay of factors contributing to this pseudotumor.
