[|Human|] I have notice a circular bruise on my daughter left side just below her rib cage. The bruise is about the size of a golf ball and the centre is lighter color almost no pigment. In the center of the center there is a small lump that is smooth and round. She complained of tenderness. Any idea of what it might be?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. She may have sebaceous cyst or some soft tissue tumor like lipoma or neurofibroma or dermatofibroma. She should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
