Area of Science:

• Dermatology
• Autoimmune Blistering Disorders

Background:

• Pemphigus foliaceus is a superficial autoimmune blistering skin disease.
• Localized variants of pemphigus foliaceus are infrequently documented in medical literature.

Observation:

• An 81-year-old male patient presented with unusual, localized facial lesions.
• The lesions followed a distinct dermatomal pattern, complicating the diagnostic process.

Findings:

• This case represents the first documented instance of localized pemphigus foliaceus exhibiting a dermatomal distribution.
• The atypical presentation underscores the diagnostic challenges associated with rare dermatological conditions.

Implications:

• Recognizing unusual presentations of pemphigus foliaceus is crucial for timely diagnosis and management.
• This case expands the understanding of pemphigus foliaceus' clinical spectrum and rare manifestations.
