Surgical excision of acne keloidalis nuchae with secondary intention healing.

Acne keloidalis nuchae (AKN) is a chronic scarring folliculitis that presents clinically as follicular papules and pustules. These can coalesce into firm hypertrophic plaques and nodules on the nape of the neck, most commonly affecting young adult men. Treatment includes topical steroids/antibiotics and oral antibiotics, but often has disappointing results. Surgical approaches include excision with primary closure or skin grafting, and hair-removal lasers. Another surgical approach is excision with secondary intention healing. This can result in good cosmesis with little or no recurrence. We report two men with AKN where treatment by excision with secondary intention was successful.
