Introduction

What is a penile rash?

A penile rash is the presence of spots or sores on the penis and possibly on other areas of the groin or genitals. It can be accompanied by itching that may be intense, and pain or tenderness. Related symptoms may include blisters; burning or pain with urination; redness, warmth or swelling; scabbing; and scar tissue.

Penile rash can be extremely uncomfortable or awkward and may create difficulty with urination, sexual relations, and daily activities. In addition to symptoms in and around your penis, and depending on the cause, penile rash can be accompanied by generalized symptoms, such as flu-like symptoms (fatigue, fever, sore throat, headache, cough, aches, and pains) and poor health in general.

Herpes is a sexually transmitted infection that can cause painful, blister-like sores on the penis and genitals. Human papillomavirus infection can cause genital warts, which may appear as multiple lumps or warts on the genital organs. Other causes of penile rash are similar to causes of rash elsewhere on the body and include psoriasis, dermatitis, chemical irritation, and allergic reactions. A scabies mite infestation may also be associated with multiple small bumps at the area of itching.

A penile rash is not an emergency, but it may be a sign of a disease that can be transmitted to others. Seek prompt medical care if symptoms persist or cause you concern.
