What causes lump on forearm?
Patient: Hi there,I have a larger lump on my forearm - just noticed it - feels like I hit my arm really hard, which I didnt, and it shows no bruising - but it is an area of what feels like swollen tissue.  It is like a golfball is sticking out of my arm, not sore to touch and slightly pink in colour, minor itchiness? It is not a solid mass either. Doctor: Hi, dearI have gone through your question. I can understand your concern. You may have some ganglion cyst or other benign cyst like sebaceous cyst.  You should go for examination. If needed go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly.surgical excision is the treatment of choice. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
