Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Area of Science:

  • Dermatology
  • Internal Medicine

Background:

  • Rosacea is a chronic inflammatory skin condition.
  • Minocycline is a common treatment for rosacea.

Purpose of the Study:

  • To describe a rare presentation of blue hyperpigmentation in a patient with rosacea.
  • To discuss the recognition and management of this finding.

Main Methods:

  • Case report of a 62-year-old male.
  • Physical examination findings documented.

Main Results:

  • The patient presented with non-palpable, non-pruritic blue patches on the medial lower extremities.
  • These findings were noted during a routine examination.

Conclusions:

  • Rare dermatological presentations can occur even with well-controlled chronic conditions.
  • Physicians should be aware of and prepared to manage unexpected skin findings.
