[|Human|] i ve had a pimple like bump on the bac of my neck for a while now it doesn t hurt but when squeezed a foul smelling puss comes out. sorry i don t feel comfortable giving out my cc information over the internet tanks though you have the email if you feel like helping me. Thanks
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Pimple like lump with foul smelling material is suggestive of sebaceous cyst or Desmond cyst.  It is purely benign lesion(non-cancerous) you should go for complete excision of lump.  Consult your doctor and 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.
