What causes a hard lump with odor on the neck?
Patient: Hi, My husband has noticed a hard lump on the back of his neck (center),it doesn't move.  It keeps getting bigger and is very painful.  It hurts to move his neck.  Today he noticed a strong odor on his finger after rubbing it.  There's no odor if you sniff the bump, but if you rub it there is a awfull odor. He is 65, weighs 165 and is 5' 11".  I'd appreciate any advice.  Thank you Linda Doctor: Hi, dearI have gone through your question. I can understand your concern. Hr may have dermoid cyst or sebaceous cyst.  It cause lump with odour.  You should go for fine needle aspiration cytology or biopsy.  It will give you exact diagnosis.  Then you should take treatment accordingly.  Surgical excision is the treatment of choice. 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 health care magic.
