Balanitis is inflammation of the glans penis.[1] When the foreskin is also affected, the proper term is balanoposthitis.[1] Balanitis on boys still in diapers must be distinguished from redness caused by ammoniacal dermatitis.[2] The word balanitis is from the Greek βάλανος balanos, literally meaning 'acorn', used because of the similarity in shape to the glans penis.[3]

Signs and symptomsEdit

  • Small red erosions on the glans (first sign)
  • Redness of the foreskin
  • Redness of the penis
  • Other rashes on the head of the penis
  • Foul smelling discharge
  • Painful foreskin and penis

ComplicationsEdit

Recurrent bouts of balanitis may cause scarring of the preputial orifice; the reduced elasticity may lead to pathologic phimosis.[4] Further complications may include:

CauseEdit

Inflammation has many possible causes, including irritation by environmental substances, physical trauma, and infection such as bacterial, viral, or fungal.[5][6] Some of these infections are sexually transmitted diseases.

It is less common among people who are circumcised, as in many cases, a dysfunction of the foreskin is a causal or contributing factor.[1] Both not enough cleaning and too much cleaning can cause problems.[1] Diabetes can make balanitis more likely, especially if the blood sugar is poorly controlled.[7]

It is important to exclude other causes of similar symptoms such as penile cancer.[1]

DiagnosisEdit

Diagnosis may include careful identification of the cause with the aid of a good patient history, swabs and cultures, and pathological examination of a biopsy.[5]

TypesEdit

TreatmentEdit

Initial treatment in adults often involves simply pulling back the foreskin and cleaning the penis.[1] However, some topical antibiotic and fungal ointments may be used for treatment for mild cases. Depending upon severity, hydrocortisone and other steroidal creams may be used upon consultation.

EpidemiologyEdit

Balanitis "is a common condition affecting 11% of adult men seen in urology clinics and 3% of children" in the United States; globally, balanitis "may occur in up to 3% of uncircumcised males".[14]

Other animalsEdit

In dogs, balanoposthitis is caused by a disruption in the integumentary system, such as a wound or intrusion of a foreign body. A dog with this condition behaves normally, with the exception of excessive licking at the prepuce, and a yellow green, pus-like discharge is usually present.

In sheep (rams/wethers), ulcerative enzootic balanoposthitis is caused by the Corynebacterium renale group (C. renale, C. pilosum & C. cystidis).

For the condition in bulls, caused by a virus see Bovine herpesvirus 1.

Balanoposthitis is believed to have contributed to the decline to near-extinction of Gilbert's potoroo.[15]
