Temporal arteritis, a large artery vasculitis, can cause scalp necrosis, a rare but serious complication. Early recognition of this skin manifestation is crucial for timely diagnosis and treatment to prevent severe outcomes like blindness.

Area of Science:

  • Vascular Medicine
  • Dermatology
  • Rheumatology

Background:

  • Temporal arteritis (giant cell arteritis) is a systemic granulomatous vasculitis impacting large and medium arteries.
  • Scalp necrosis is an infrequent complication of temporal arteritis, potentially occurring at any stage of the disease, including during or after treatment.

Observation:

  • This case report details a patient diagnosed with temporal arteritis presenting with scalp necrosis.
  • Literature review on scalp necrosis in temporal arteritis was conducted.

Findings:

  • Scalp necrosis manifests in a subset of temporal arteritis patients, typically affecting the frontal, parietal, and temporal scalp bilaterally.
  • This skin complication often indicates severe, widespread vasculitis, correlating with a high risk of associated complications, notably visual disturbances and blindness.

Implications:

  • Increased awareness of scalp necrosis as a temporal arteritis complication can expedite diagnosis and treatment initiation.
  • Prompt recognition may reduce diagnostic delays and prevent severe sequelae, such as vision loss.
