A 55-year-old man presents with a 1.2 cm ulcerative lesion on the glans penis. Biopsy shows well-differentiated squamous cell carcinoma invading the corpus spongiosum (T2). What is the minimum recommended surgical margin for penile carcinoma?
- A 2 cm ✓
- B 1 cm
- C 5 mm
- D 3 cm
Correct answer: A. 2 cm
Explanation
C 2 cm surgical margin is the standard recommendation for invasive penile carcinoma to achieve negative margins and reduce local recurrence. For carcinoma in situ and select early lesions, 5-10 mm margins may be acceptable with organ-sparing approaches. For invasive T2 disease, a 2 cm margin is required, often necessitating partial penectomy.
