Expert: Arthur Goldstein, M.D.
Date: 9/5/2008
Subject: FLAKY SKIN ON PENIS
Question
Dear Dr. Goldstein,
I noticed for the last one week, a small 2mm oval shaped area of flaky whitish patch on the penis shaft, 1 week prior i noticed 2 small approx 3mm circular/oval shaped "patch" at the base of the penis (on the sharft but lower) I dont have any on the glans. I have dark skin and these areas are flaky and whitish, when i rub the "flake" off it leaves a light red/pinkish color, and is shinnier than the surrounding skin. there is no pain, raised red borders, discharge, fever, chills, etc. it DOES NOT itch. I am sexually active, monogomous for 8 years, but we dont use very much lubrication. My question is this fungus, eczema , irritation? Any thoughts. thanks.
Answer
J, as you might imagine, for this type of problem it is not possible for me to make an exact diagnosis over the internet because of the inability to do a physical examination. However, I shall try to help you. Common causes would be a yeast or fungal infection, contact dermatitis, or a primary dermatologic condition (such a psoriasis, eczema, lichen planus, etc.). Bacterial infections usually involve the penile glans & occur almost exclusively in uncircumcised men. Since your lesions spare the glans, a bacterial cause is unlikely. Yeast and fungal infection usually respond to a 10 day course of medication such as Lotrimin cream. Contact dermatoses are much more difficult to track down as it usually infers that your penis is touching something it is allergic to. This can be a substance on your hands such as chemicals used at work, soaps, detergents used for under clothes, condoms, feminine hygiene sprays your partner might use, etc. The treatment is eliminating the cause and using at least 1% hydrocortisone or another steroid cream as needed. If your problem is refractory, consultation with a urologist or dermatologist is suggested. Good luck.
