1. BALANITIS

1.1. Introduction

Balanitis is defined as inflammation of the glans penis. The condition often involves the prepuce and the term balano-posthitis should be used.

1.2. Aetiology

According to the different aetiology, balanitis can be classified into various clinical varieties:

1.2.1. Infective

This is the commonest cause of balanitis.

1) Candidal balanitis

Candidal balanitis most frequently follows intercourse with an infected sexual partner. However, infection may occur without sexual contact, usually in diabetic patients or patients taking oral Antibiotics . The pathogenicity of the yeast depends on the host factors. There is no significant difference between carriage rate in circumcised and uncircumcised male although the chance of symptomatic infection is higher in the uncircumcised men.

The clinical features include a non-purulent surface, a slightly scaling edge and eroded satellite pustules. The groins may also be affected. Microscopy and culture confirm the diagnosis and should be taken from both partners and from the anal as well as the genital areas.

Recurrent candidal balanitis causes fissuring of the prepuce, with fibrosis and sclerosis.
