Area of Science:

  • Dermatology
  • Pathology
  • Lipid Metabolism

Context:

  • Xanthomas are visible skin manifestations of localized lipid deposition.
  • These lesions can occur in dermal tissues or tendons.
  • Their appearance varies, often presenting as yellow-orange nodules.

Purpose:

  • To define xanthomas and their histological characteristics.
  • To explore the association between xanthomas and hyperlipoproteinemia (genetic or secondary).
  • To highlight the diagnostic approach and potential links to rare diseases.

Summary:

  • Histologically, xanthomas feature lipid-laden histiocytes, fibroblasts, macrophages, and Touton cells.
  • They can appear anywhere on the body and are typically yellow-orange.
  • Medical assessment, including blood tests and physical examination, is crucial for diagnosis and management.
