Circular dermatitis presents a consistent morphological appearance around various benign and malignant skin lesions. This inflammation does not macroscopically affect the central lesions, regardless of their type.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Circular dermatitis, also known as erythema gyratum, is a skin reaction characterized by ring-like rashes.
  • The association between circular dermatitis and various underlying skin lesions, both benign and malignant, requires further investigation.

Purpose of the Study:

  • To examine the morphological characteristics of circular dermatitis occurring around diverse benign and malignant skin lesions.
  • To determine if the nature of the central lesion influences the appearance of the surrounding dermatitis.

Main Methods:

  • Observational study involving 19 patients with circular dermatitis.
  • Macroscopic examination of the skin lesions and surrounding dermatitis.

Main Results:

  • Circular dermatitis exhibited a uniform morphological appearance irrespective of the underlying lesion.

  • The study included various lesions such as acquired and congenital naevus cell naevi, seborrheic keratosis, stucco-keratosis, keloid, benign lentigo, insect bite, basal cell carcinoma, and squamous cell carcinoma.
  • Central lesions remained macroscopically unaffected by the surrounding inflammatory reaction.

    • Conclusions:

    • The morphological presentation of circular dermatitis is consistent across a wide spectrum of benign and malignant skin conditions.
    • The surrounding inflammation in circular dermatitis does not appear to alter the macroscopic appearance of the primary lesion.
