[|Human|] I am a 37 year old male.  Tonight I noticed a lump the back of my right leg just below the calf muscle.  It would best be described as a roll about half an inch tall from top to bottom and running across the back of my leg.  No pain.  I occasionally have a little swelling around my dress sock line, but this appears to be different.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some soft tissue tumor like lipoma, neurofibroma., dermatofibroma. Or some benign cyst or ganglion cyst.  You 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.
