Balanitis

Summary

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]

Balanitis
Inflammation of the glans penis and the preputial mucosa of a circumcised penis (balanitis)
SpecialtyUrology
Balanitis caused by smegma

Signs and symptoms edit

  • 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

Complications edit

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

Cause edit

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

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]

Diagnosis edit

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]

Types edit

Treatment edit

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.

Epidemiology edit

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".[13]

Other animals edit

 
Prepuce of a dog affected by balanoposthitis

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.[14]
