Area of Science:

  • Dermatology
  • Histopathology

Background:

  • Collagenomas are characterized by excessive collagen deposition in the dermis, classified as connective tissue nevi.
  • Understanding the pathogenesis of collagenomas is crucial for diagnosing and managing these benign skin growths.

Observation:

  • A unique case of acquired eruptive collagenomas is presented, manifesting on both ears.
  • The patient exhibited multiple, distinct lesions consistent with collagenoma development.

Findings:

  • Histological examination revealed significant thickening of the dermis.
  • This dermal thickening was attributed to an excessive deposition of collagen, confirming the diagnosis of collagenoma.

Implications:

  • This case expands the clinical presentation of collagenomas, highlighting acquired eruptive forms.

  • Further research into the triggers and mechanisms of acquired eruptive collagenomas may be warranted.
  • Accurate histological diagnosis is essential for differentiating collagenomas from other dermal conditions.
