[|Human|] The skin on my right lower arm and slightly above the elbow has irregularly-shaped brown patches that look like old scars. None of these areas are raised and you can t feel any difference in the skin texture. There is no irritation or itching associated. I m not bothered by these patches except that I often am asked what happened to your arm? and would just like to know what it is?
[|AI|]  Hi.thanks for your query. The patches of the arms may be a result of any injury/ inflammation/skin disorder that might have occurred in the past. You should be able to elicit a history in such cases. The next possibility is of a nevus, which we commonly call a birthmark.there are several types of the same. There may be associated patches elsewhere in the body as well. The only way to know the exact cause is to visit a dermatologist who can guide you by looking at the morphology of the patch. Also, a definitive diagnosis a be attained by doing a punch biopsy of a part of the patch. Hope this helps. Take care!
