Prostate cancer can rarely invade the rectum, causing symptoms that mimic rectal cancer. This case highlights the importance of considering prostate cancer in older men with rectal symptoms and no urinary issues.
Area of Science:
- Oncology
- Urology
- Gastroenterology
Background:
- Prostate cancer (PC) diagnosis has shifted from symptomatic presentation to early detection via screening. However, advanced PC can present atypically.
- Rectal cancer symptoms can overlap with other conditions, complicating differential diagnosis.
Observation:
- An 86-year-old male presented with diarrhea and rectal bleeding, lacking typical lower urinary tract symptoms.
- Initial clinical presentation suggested a gastrointestinal issue rather than a urological malignancy.
Findings:
- Investigations revealed advanced prostate cancer infiltrating the rectum.
- The patient's symptoms were directly attributable to rectal invasion by prostate cancer.
Implications:
- This case underscores the need to consider prostate cancer in the differential diagnosis of rectal symptoms, especially in elderly men.
- Diagnostic challenges exist when prostate cancer mimics rectal cancer, necessitating comprehensive evaluation.
- Early detection strategies for prostate cancer may need to account for rare presentations involving rectal invasion.
