A Rare Form of Suppurating and Cicatrizing Disease of the Scalp

Perifolliculitis capitis abscedens et suffodiens is a rare chronic inflammatory scalp disease characterized by perifollicular suppuration and extensive undermining, leading to cicatrizing alopecia. First described by E. Hoffmann in 1907, the condition presents with numerous hairless, pus-exuding nodules and fistulae, resulting in a rough, uneven scalp appearance. Treatment with a 10% sulfur-zinc paste hastened healing, though it resulted in further scarring. The disease is not widely documented outside of German dermatological literature, with no records found in American, British, French, or Italian publications.
