What causes cluster of bumps on penis?
Patient: Small cluster of skin tone bumps on penis about 3-4 cm from the head...hard to the touch but painless unless rubbed against clothing while walking which gives a minor tingling or itching feeling...no redness or blister like bumps with any kind of color Doctor: HelloThanks for query .Based on what you have described I would say that you have what is called as Fordyces spots over shaft of the penis .The penile  skin is rich in sebaceous glands and hence prone to get more sebaceous cyst due to accumulation of sebum beneath the skin. Normally they fade away without treatment however they need to be treated if increase in size or get infected. Dr.Patil.
