What causes brown patches on the skin?
Patient: Hi. I have a 9 month old daughter , she has got brown pathches and we consulted the skin specialist , they said it is just an molted spots and gave skin cream to apply on it and will get fade as she grows . Am afraid if its NF. Is it possible to DNA test and find out the same. please could you give me some help Doctor: HiCafe au lait spots also can give brownish coffee coloured appearance on skin. But it's very unlikely to be missed by any trained doctors. Six or more café-au-lait spots or hyperpigmented macules =5 mm in diameter in prepubertal children and 15 mm postpubertal if present than a thorough examination and laboratory evaluation to rule out neurofibromatosis will be useful.Hopefully it will be of help. I would be happy to help you in any further questions. Take care
