    Dear Johnlock,

    It appears you have two scrotal lumps- one larger one at top right corner and a smaller lesion to the left margin of the photo. They are sebaceous (epidermoid) cysts (Google) and are entirely benign in nature. The cysts develop if the sebaceous gland or its duct becomes damaged or blocked. If you want them removed, you will need to have them excised under local. It's a relatively straightforward procedure and some GPs/Family doctors who are trained in minor surgery should be able to carry this out.

    Don't bother cutting or pricking the cyst yourself- they are likely to re-form and you may also run the risk of infection.

      Do you know if there are any ways to prevent getting them? I think I am fairly prone to getting them but I shower twice a day so I don't think its a cleanliness issue?

      Dear john,

      There's no easy way of preventing them. These types of cysts are more common in young and middle-aged men and not in pre-pubertal boys so there's clearly a male predisposition, likely to be related to circulating androgen/testosterone levels. The risk could also be enhanced by exogenous androgenic anabolic steroid (mis)use. Sebaceous cysts can also arise from damage to the hair follicle itself (acne) and rarely from a genetic condition known as Gardner's syndrome.
