Dermatology is the branch of medicine dealing with the skin, nails, hair and its diseases. It is a specialty with both medical and surgical aspects. A dermatologist treats diseases, in the widest sense, and some cosmetic problems of the skin, scalp, hair, and nails.
Balanitis is swelling of the foreskin, or head of the penis. Balanitis affects roughly 1 in 20 males.
Balanitis is inflammation typically caused by infections or chronic skin conditions. Improper hygiene can contribute to skin irritation. Both inadequate cleansing and too much cleansing can add to this problem. The condition is often caused by an overgrowth of either bacteria or yeast. The foreskin of the penis is an ideal place for these organisms to grow because it can trap moisture around the penis head.
Injuries on the tip of the penis or foreskin can cause swelling and discomfort.
