C45. Tumors of the penis, scrotum, and urethra.
Penile cancer
Penile cancer (cancer of the penis) is relatively rare. It's more common in elderly and in developing countries. In almost all cases penile cancer is squamous cell carcinoma.
Etiology
- HPV
- Poor hygiene
- Phimosis
- Chronic balanitis
Precancerous lesions
- Bowen disease
- Erythroplasia of Queyrat
Clinical features
- Most commonly in the glans
- Painless lump or ulcerative lesion on penis
- Swollen inguinal lymph node
Diagnosis
- Histological diagnosis
- Excisional biopsy
- Gold standard
Differential
- Condyloma acuminata
- STD
Treatment
- Partial penectomy
- If penile length is adequate after surgical excision with a 2 cm margin
- Total penectomy
- A urethrostomy is made on the perineum
- T1 tumour
- Hasn’t invaded any of the corpora
- Surgical excision, laser ablation, radiotherapy
- T2 – T4 or N+ tumour
- Partial or total penectomy
- Ipsilateral lymph node dissection (if N+)
- Adjuvant chemotherapy
- Metastatic disease
- Palliative chemotherapy
Scrotal cancer
Scrotal cancer is a rare cancer. In most cases it's a squamous cell carcinoma. It's related to topical carcinogens: soot, tar, etc. and poor hygiene. It usually presents as a painless, slow growing mass or ulceration. Diagnosis is made by biopsy. The treatment is surgical excision.
Urethral cancer
Urethral cancer is rare. It's more common in females. 70% of cases are squamous cell carcinoma and the remaining are urothelial carcinoma. It usually presents as an obstruction of urine or haematuria. Diagnosis is by biopsy.
- Treatment of proximal urethral cancer
- Radical cystourethrectomy + inguinal lymph node removal + urine deviation
- Treatment of distal urethral cancer
- Women – surgical resection + radiation
- Men – transurethral resection, amputation, or radiation
