I had a look at this link...I don't think this is the same thing at all...Does the lump look like its under the skin? Lymphocystis is generally found to be more topical...This might be one for VickiandKev to have a look at, as I haven't seen this before.I've read about L200 having lumps and bumps, not sure what the cause was but read in a thread elsewhere about a possible cause and that it could be treated with furanase,

If anyone else has any suggestions about what it could be feel free to post
