What characterizes the lesion known as erythroplasia of Queyrat?

What complication is associated with lymphogranuloma venereum?

What is the typical presentation of testicular torsion in adolescents?

Which serotypes of Chlamydia trachomatis are associated with lymphogranuloma venereum?

Hypospadias

Opening of urethra on inferior surface of penis
Due to failure of urethral folds to close

Epispadias

Opening of urethra on superior surface of penis
Due to abnormal positioning of genital tubercle
Associated with bladder exstrophy

Condylomata Acuminata

Benign warty growth on genital skin
Due to HPV types 6 or 11
Characterised by koilocytic change

Lymphogranuloma Venereum

Necrotizing granulomatous inflammation of inguinal lymphatics and lymph nodes
Sexually transmitted disease caused by Chlamydia trachomatis (serotypes L1-L3)
Can lead to rectal stricture with perianal involvement

Squamous Cell Carcinoma

Malignant proliferation of squamous cells in penile skin
Risk factors include high-risk HPV (in ~2/3 of cases) and lack of circumcision
Foreskin can be a nidus for inflammation if not properly maintained
Precursor in situ lesions include:
- Bowen disease (leukoplakia) –in situ carcinoma of penile shaft or scrotum
- Erythroplasia of Queyrat (erythroplakia) – in situ carcinoma on glans
- Bowenoid papulosis – in situ carcinoma presented as multiple reddish papules
- Seen in younger patients (40s) relative to Bowen disease and erythroplasia of Queyrat.
- Does not progress to invasive carcinoma.

This quiz covers various urological conditions, including hypospadias, epispadias, condylomata acuminata, lymphogranuloma venereum, and squamous cell carcinoma. Each condition is discussed in terms of its characteristics, causes, and associated risks. Perfect for those studying urology or related medical fields.
