Scales on the scalp
AbstractA five-year-old boy presented with a six-week history of scales, flaking and crusting of the scalp. He had mild pruritus but no pain. He did not have a history of atopy and there were no pets at home. Examination of the scalp showed thick, yellowish dry crusts on the vertex and parietal areas and the hair was adhered to the scalp in clumps. There was non-scarring alopecia and mild erythema. There was no cervical or occipital lymphadenopathy. The patient’s nails and skin in other parts of the body were normal. (copied from article)
