Spots on the penis are very common and most do not have a serious cause. However, some do and it is important to seek prompt medical advice if you are concerned.
Spots on the penis can be divided into groups according to their appearance.
Ulcers: ulcers appear as craters on the skin and represent a full-thickness loss of skin (epidermis). There is frequently a crust, clear liquid (serum) or pus in the crater.
Papules: papules are small (less than 1cm diameter) lesions (lumps) raised above the skin surface.
Plaques: plaques are raised, flat-topped lesions, greater than 1cm in diameter.
You need to get a professional to check them out - if too embarrassed to go to GP try a clinic like a GUM unit.
