Diffuse partial woolly hair (DPWH) is a rare disturbance of hair growth, first described in 1987 by Ormerod et al. Patients affected with this condition present two distinct hair populations: straight, blond or brown, long hair shafts interspaced with short, fine, hypopigmented and curly shafts. Ormerod et al. considered DPWH being a separate entity on the woolly hair group, which underlying genetic defect is unknown. Dermoscopy shows hair shafts with waves that have very short intervals, giving the hair a "crawling snake" appearance. Hutchinson et al. classified it in three distinct types: hereditary, familial and woolly hair nevus. Woolly hair can also appear as part of systemic syndromes, such as Naxos disease and Carvajal syndrome, that are both clinically characterized by cardiomyopathy, palmoplantar keratoderma and woolly hair. We report the case of an 11-year-old boy with dermatoscopic and histopathologic findings of DPWH.
