QUESTION: hi doctor i would like a ask if penile lichen planus can be triggered by an urinary tract infection and/or the treatment with peniciline.thanks in advance



Lichen planus is not triggered by a UTI and is not treated with penicillin.  It is usually treated as an auto-immune type illness so treatment involves mostly anti-histamines and steroids.

UTIs and antibiotics can sometimes lead to an overgrowth of yeast or candida infections which are not related to lichen planus.  These types of infections are treated with specific anti-yeast medications and creams.

QUESTION: Thanks for the reply.Does the pic that i send you at least look like lichen planus?I have already been diagnosed with lp but this lesion does not look like like the pics on the google.Your opinion would be apreciated.


Sorry, but we are not permitted to give specific advice or diagnoses on this forum; just answer general questions. In addition, it would be extremely unreliable and possibly even dangerous to try and make a diagnosis and suggest treatment based only on a brief description and/or a picture, particularly of a skin lesion on the penis or male genitalia.
Most of the time, skin lesions on the male genitals are quite benign with cysts, allergic reactions and infections like yeast or Herpes being the most common findings.  Sexually transmitted diseases can also cause visible skin lesions.  That is why we recommend that you contact your regular physician or consult a local dermatologist as they are the most experienced experts in skin problems of the male genitalia.
