Squamous cell carcinoma of the penis
Diagnosis in short
Gross mass lesion, scaly patches/nodules, usu. erythematous, +/-ulceration.
Site penis
Clinical history uncircumcised
Prevalence uncommon overall, most common form of penis cancer
Prognosis good
Treatment surgery

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.

Microscopic

Features:

Notes:

DDx:

  • Squamous dysplasia.

Staging

T-stage:

  • pT1a - subepithelial tissue involved, no LVI, not poorly differentiated (G3 or G4).
  • pT1b - subepithelial tissue involved with LVI or poorly differentiated.
  • pT2 - corpus spongiosum or cavernosum involved.
  • pT3 - urethral involvement.
  • pT4 - adjacent structure(s) involved.

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. No lymphovascular invasion is identified. No 
lymphovascular invasion is identified. No corpus spongiosum or corpus cavernosum
invasion is seen. The staging is unchanged.
