Acne Keloidalis Nuchae: A Case Series of Four Indian Patients

The document described a case series of four Indian patients with acne keloidalis nuchae (AKN), an inflammatory disease associated with keloidal scarring alopecias. These patients also had acanthosis nigricans, a skin marker for metabolic syndrome, particularly obesity. Notably, common risk factors for AKN, such as curly hair or helmet use, were absent in these cases. The authors proposed that AKN might be a cutaneous marker for metabolic syndrome, suggesting the need for case-control studies to validate this observation. They hoped their findings would encourage further research into this potential association.
