###Human: I have a hard lump on bikini line. Is it something serious? ###Assistant: Hi. I have gone through your case. Yes, in very rare cases psoriasis and lymphoma can be correlated but it occurs very rarely. In lymphoma, lymph node becomes enlarged and that do occur in your whole body. In those cases, lesions are not inflamed, not red as is your lesion right now (attachment removed to protect patient identity). In my opinion, it looks to be due to local infection like hair follicle infection. Take capsule Amoxil 500 mg three times a day. Tablet Brufen 400 mg two times a day. Apply Fusidic acid cream three times a day. Hopefully, it will settle in a week. All this medicine is for a week. Just relax clinically, it is not a sign of lymphoma. Take opinion after a week of treatment.
