Squamous cell carcinoma of the penis is the most common malignancy of the penis.
Penile cancer redirects to this article.
General
- Not very common overall.[1]
- Most common form of penile 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.
- Usually erythematous.
- +/-Ulceration.
Microscopic
Features:
Notes:
- Usually grade 2.[1]
- Lymphovascular invasion - prognostically important,[3] and changes the T-stage for pT1a tumours to pT1b.
DDx:
- Squamous dysplasia.
- Pseudoepitheliomatous hyperplasia.
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.
