Patient: Adter lookin at some pictures its clear to me that I have  Some fordyce spots on mypenis and testes but there is also a few (2-3mm) hard yellowy puss coloured spots also on my balls, was just wondering if they were just another different looking version or whether I have something to worry about. Thanks. Doctor: fordyce spots are nothing but visible sebaceous glands.they usually dont need any treatment.they are usually yellow,black,brown in colour.
