<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a lump on the bottom of my thigh about 4 inches above my knee, there are novels on the skin and has been there for a few months, it doesnt hurt but feels it is getting larger slowly, it feels softish and I would say oval in size not perfect circle. What could it be?  <response>: Hi! Thanks for writing to us and sharing the details of the lump on the bottom of your thigh! Well, if I were your family physician, I would think of six possibilities in your case like:1. Lipoma or just a benign fatty tumor2. Neurofibroma, again a benign tumor3. Bursa like a degenerativeinflammatory pseudocyst4. Sebaceous cyst or some ganglion cyst5. Infective pathology like abscesstuberculosis6. Some stromal humorously an FNAC testbiopsyultrasonography could confirm the nature of this lesion; therefore see your doctor for this and revert to us if necessary! Hope you got the answer; wishing you good health...
