Hi,
This sounds like a fungal infection.
Culture of the flakes or scrapings of the involved area may help ascertain the diagnosis.Try to keep the area dry at all times.Fungal infections may present with itchiness, redness and scaling.The well demarcated red border of a fungal infection may differentiate this from a dermatitis.
Have this assessed by your physician.Avoid sharing any towels and wear light cotton underpants.Use only mild and bland cleanser in washing the area.
thank you Vanessa, i have no lesions anywhere else on my body.
the condition is very itchy and the lesions switch between white and flaky and red and sore.
Hi,
You describe the skin condition as recurrent ,flaky, dry and white patches in the penile shaft and in the underside of the scrotum ( is this correct?).
Differentials for this will be a fungal infection, a contact dermatitis,allergic dermatitis,irritant dermatitis , and a psoriatic lesion.
Do you have any similar lesions in other parts of the body?
I suggest that you get a second opinion for your case.Fungal infections, dermatitis and psoriasis all respond to corticosteroids.For the meantime, a culture of the scales or flakes may help ascertain the diagnosis of your skin condition.
Refrain from any sexual activity for the moment until a diagnosis has been made.
