I am 48 years old, a few purple colors spot on head and before two years I was go to hospital and doctor said it is lichen planus. He checked the whole body even genital part but there was no spot on other parts of body.  At present some small red color spot on my penis head.  what is this please tell me.
HIT hanks for posting your query to Chat Doctor It could be Lichen Plans only but since it has happened over Genitalia other conditions also must also be considered.  I need to know whether you had any unprotected sex recently, in that case we need to consider Sexually transmitted Diseases first.  Also let me know whether you have been started on any medications as Chat Doctor.  I would recommend you either re visit your doctor or kindly upload the pictures so that I can see and diagnose what it is. Hope this information was useful to you. Any clarifications feel free to ask. Regards.
