Acne keloidalis nuchae - Hair and Scalp
Keloids at other locations or having a family history of keloids are not features of the disease. The overwhelming majority of patients with AKN are young adult African American or Hispanic men, especially those with coarse, curly hair. Women are rarely affected unless they shave their hair at the nape of the neck. AKN is rare in pre-pubertal children.
