Abstract
Introduction
We report a case of small cell carcinoma of the prostate (SCCP) which is a rare, high-grade malignant neoplasm accounting for 1% of all prostate cancers (CPa).
Case
Presentation
A 56-year-old male patient initially presented to primary care with a six-month history of frequency, nocturia and pain in the perineal region when seated. A positive family-history for CPa was noted, serum PSA was 11.58, and a rectal examination found a large, irregular mass. He was treated with antibiotics for possible prostatitis and referred to the colorectal team. MRI rectum confirmed a mass between the prostate and rectum, which was found to be pure SCCP on biopsy. Whole-body scanning found multiple lung and pelvic metastases. The patient was commenced on six cycles of Etoposide and Carboplatin therapy. The patient reported that his pelvic discomfort has improved following the first cycle.
Conclusions
SCCP metastasizes early and therefore the clinical presentation is often in an advanced stage. It is noted that there is limited value of serum PSA for SCCP diagnosis. Instead, pathological examinations and MRI rectum are vital. In terms of treatment, chemotherapy provides relief of the clinical symptoms and its use is in in accordance with the 2016 National Comprehensive Cancer Network guidelines.
