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
