Scalp Necrosis Revealing Severe Giant-Cell Arteritis

Area of Science:

• Rheumatology
• Vascular Medicine
• Dermatology

Background:

• Giant-cell arteritis (GCA), or temporal arteritis, is the most prevalent primary vasculitis affecting older adults.
• It primarily involves extracranial branches of the carotid arteries, notably the temporal artery.
• Typical symptoms include headaches, visual disturbances, fever, and scalp tenderness.

Observation:

• Scalp necrosis is an exceptionally rare complication of GCA, with fewer than 100 documented cases.
• This severe manifestation necessitates immediate medical intervention due to the risk of permanent vision impairment.
• The case presented here involves scalp necrosis as the initial indicator of GCA.

Findings:

• The patient's scalp necrosis served as the presenting sign for Giant-cell arteritis.
• This finding underscores the potential for GCA to manifest with unusual dermatological symptoms.

Implications:

• Increased awareness of scalp necrosis as a GCA complication is crucial for timely diagnosis and management.
• Early recognition and treatment are vital to avert irreversible vision loss in GCA patients.
• This case contributes to the understanding of rare GCA presentations and their clinical significance.
