[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some enlarged lymph node due to reactive hyperplasia, tuberculosis or lymphoma. Or it can be some soft tissue tumor, cyst or skin adnexal tumor.  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. Wish you a very good health.
