A 30 year-old Brazilian woman of skin phototype IV and pregnant for 35 weeks sought medical care for presenting hyperchromic lines on both legs for 5 weeks. Hyperchromia in the axillae and groin, which had appeared earlier in the pregnancy, were concurrent complaints. There were no associated symptoms. She had a history of gestational diabetes, which was been treated with NPH insulin since the 26th week of pregnancy and was under control. It was her second pregnancy, and she denied similar alterations in the previous one. Hormonal disorders had been previously discarded by an endocrinologist. Physical examination revealed demarcation lines from the perineum to the posteromedial portion of the thighs extending to the ankles through the popliteal fossae, bilaterally and symmetrically, in the interface between a hyperchromic lateral portion and a lighter medial portion ( and ). Hyperchromic axillae and prominent linea alba were also seen.
We present a 3-year-old healthy girl, whose mother was concerned about recent hair changes. The patient had no personal or family history of cutaneous diseases. At physical exam, the girl had a phototype II skin, normal teeth and nails. The back of the scalp revealed a well-circumscribed patch of kinky, curly light blonde hair. The rest of the physical exam was normal. Dermoscopy was not performed at the time.\nWoolly hair nevus was diagnosed. The parents were counseled about the benign and chronic nature of this lesion. Ophthalmologic evaluation was recommended, but the parents of the patient refused. No further studies were performed [Figures and ].
