Summary
Penile squamous cell carcinoma (SCC) has several subtypes with varying aggressiveness. Understanding these histologic subtypes is crucial for accurate diagnosis and treatment of penile cancer.
Area of Science:
- Oncology
- Pathology
Background:
- Penile squamous cell carcinoma (SCC) is the most common penile malignancy.
- Histologic subtypes of penile SCC exhibit distinct clinicopathologic features and prognoses.
Purpose of the Study:
- To outline the clinicopathologic and outcome features of various penile SCC subtypes.
- To provide an algorithm for histologic classification of penile SCC.
- To offer recommendations for handling penile cancer specimens and pathology reports.
Main Methods:
- Review of clinicopathologic and outcome data for penile SCC subtypes.
- Development of a histologic classification algorithm.
- Formulation of recommendations for specimen handling and reporting.
Main Results:
- Usual SCC is the most common subtype (50-66%).
- Verruciform tumors (verrucous, warty, papillary) are low-grade with low metastatic potential.
- Basaloid and sarcomatoid carcinomas are highly aggressive.
- Rare variants include carcinoma cuniculatum, pseudohyperplastic, adenosquamous, and acantholytic carcinomas.
Conclusions:
- Accurate histologic classification of penile SCC subtypes is essential for predicting patient outcomes.
- The proposed algorithm can aid pathologists in classifying penile SCC.
- Standardized handling of specimens and pathology reports improves diagnostic accuracy and patient care.
