[|Human|] Hi, a few years ago i had a mosquito bite on my leg.. or what i thought was a bite... it was itchy and it bled a few times... its healed over, but its left a brown, hard, small lump on the side of my leg. it doesnt hurt when i touch it, is it a skin cancer?
[|AI|]  Hi ! Good morning. I am Chat Doctor answering your query. Considering the duration of your symptoms, it seems less likely to be a skin cancer. With all probabilities it is a type of benign kind of abnormal wound healing (either a hypertrophied scar or a keloid). Hypertrophic scar is self limiting problem, whereas keloid might spread away from the original scar. However, I would advise you to get it examined and confirmed by a general surgeon/dermatologist to be sure and for proper management. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor.
