Spitzer first described the disease in 1903, and hoffman named it descriptively in 1907. If you think that you may have this you should see an experienced dermatologist and follow their directions.

A rare scalp disease: Perifolliculitis capitis is a rare disease of the scalp that is difficult to treat. It occurs primarily in black males in their fourth decade of life and is characterized by perifollicular pustules, nodules, and abscesses, with interconnecting sinus tracts that drain pus or blood. It usually runs a chronic course with unpredictable relapses, although spontaneous resolution is possible.
