Overview

Balanitis is inflammation of glans penis. When inflammation involves the foreskin and prepuce, it is termed as balanoposthitis. Based on the etiology, balanitis can be mainly categorized into infectious, inflammatory dermatoses, and penile carcinoma in situ. Patients with balanitis may present with asymptomatic or symptomatic lesions with itch or pain in the genital region. Risk factors, pathogenesis, clinical presentation, diagnosis and management varies from etiology to etiology.

Classification

There is no established classification system for Balantis. Based on the etiologies, Balanitis can be classified into:

• Infectious
• Non-infectious balanitis

• Zoon's balanitis
• Balanitis xerotica obliterans
