Unusually extensive scalp ulcerations manifested in pemphigus erythematosus

Senear-Usher Syndrome, or pemphigus erythematosus, is an autoimmune skin blistering disorder with an overlapping clinical presentation of pemphigus foliaceus and lupus erythematosus. Lesions typically involve the scalp, face, and upper chest or back. This case study focuses on a patient who presentedwith progressive scalp ulcers, hyperpigmentation, and eroded plaques with overlying hemorrhagic crust. Pemphigus erythematosus was diagnosedwith direct immunofluorescence, demonstrating immunoglobulin G and complement deposition both intercellularly and at the dermoepidermal junction. The patient is continuing treatment with systemicsteroids and steroid-sparing immunosuppressants
