Study Notes
Hypospadias
- Opening of the urethra on the inferior surface of the penis
- Caused by failure of the urethral folds to close
Epispadias
- Opening of the urethra on the superior surface of the penis
- Due to abnormal positioning of the genital tubercle
- Associated with bladder exstrophy
Condyloma Acuminatum
- Benign warty growth on genital skin
- Caused by HPV type 6 or 11
- Characterized by koilocytic change (Figure 14.1)
Lymphogranuloma Venereum
- Necrotizing granulomatous inflammation of the inguinal lymphatics and lymph nodes
- Sexually transmitted infection caused by Chlamydia trachomatis (serotypes L1-L3)
- Can lead to fibrosis and perianal involvement, potentially causing rectal stricture
Squamous Cell Carcinoma
- Malignant proliferation of squamous cells of the penile skin
- Risk factors:
- High-risk HPV (in two-thirds of cases)
- Lack of circumcision (foreskin acts as a nidus for inflammation and irritation if not properly maintained)
- Precursor in situ lesions:
- Bowen disease (in situ carcinoma of the penile shaft or scrotum that presents as leukoplakia)
- Erythroplasia of Queyrat (in situ carcinoma on the glans that presents as erythroplakia)
- Bowenoid papulosis (in situ carcinoma that presents as multiple reddish papules, more common in younger patients, and does not progress to invasive carcinoma)
