Area of Science:

  • Dermatology
  • Endocrinology
  • Oncology

Background:

  • Acanthosis nigricans (AN) is a visually distinctive dermatosis.
  • AN is frequently associated with various internal conditions, both benign and malignant.
  • Insulin resistance is a key factor in benign AN development.

Purpose of the Study:

  • To review the diagnostic and etiological associations of Acanthosis Nigricans.
  • To elucidate the role of insulin resistance in AN.
  • To explore the link between AN and malignancy.

Main Methods:

  • Literature review of Acanthosis Nigricans.
  • Analysis of AN associations with endocrine and oncologic conditions.
  • Review of pathogenetic mechanisms.

Main Results:

  • AN diagnosis is straightforward due to its characteristic appearance.
  • Insulin resistance is a primary driver for AN in benign conditions.
  • The pathogenesis of AN in malignant conditions requires further investigation.

Conclusions:

  • AN is a crucial cutaneous marker for underlying systemic diseases.
  • While AN itself rarely needs treatment, identifying and managing the associated internal condition is paramount.
  • Further research is needed to fully understand AN's association with malignancies.
