Squamous cell carcinoma of the penis is the most common malignancy of the penis.

General

  • Not very common overall.[1]
  • Most common form of penis cancer.
    • Non-squamous penis cancer only ~5% of cases.[2]

Epidemiology:[1]

  • Median age ~ 67 years old.
  • Usually a good outcome - 5 year cause specific survival ~ 81%.[1]

Gross

  • Scaly patches/nodules.
  • Usu. erythematous.
  • +/-Ulceration.

TIP OF PENIS, PARTIAL PENECTOMY:
- INVASIVE SQUAMOUS CELL CARCINOMA, MODERATELY DIFFERENTIATED.
-- SURGICAL MARGINS NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.
-- PLEASE SEE TUMOUR SUMMARY.

TIP OF PENIS, PARTIAL PENECTOMY:
- INVASIVE SQUAMOUS CELL CARCINOMA OF CORONAL SULCUS, MODERATELY DIFFERENTIATED.
-- SURGICAL MARGINS NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY.
- LICHEN SCLEROSIS.
- POST-SURGICAL CHANGES (GRANULOMATOUS INFLAMMATION (NON-NECROTIZING), SIDEROPHAGES).

COMMENT:
This lesion was previously excised. The surgical clearance is 1 mm. The tumour 
thickness is approximately 4 mm.
