Summary
Small-cell carcinoma of the prostate is a rare and aggressive cancer. This review of 8 cases suggests it may arise from totipotential basal cells with dual differentiation potential.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Small-cell carcinoma of the prostate (SCCP) is an uncommon but highly lethal malignancy.
- SCCP can present as a pure small-cell type or a mixed pattern with adenocarcinoma.
Observation:
- This report details 2 new cases of SCCP and reviews 6 previously reported cases.
- Microscopic examination reveals tumors resembling pulmonary small-cell carcinoma or mixed patterns.
Findings:
- The totipotential basal cells of prostatic acini are the likely origin of SCCP.
- These basal cells possess the capacity for dual differentiation into adenocarcinoma and small-cell carcinoma.
Implications:
- Understanding the cellular origin of SCCP is crucial for developing targeted therapies.
- Further research into the differentiation pathways of prostatic basal cells may elucidate SCCP development.
