## TL;DR

An older man with fatigue and urinary symptoms was found to have metastatic prostate cancer, emphasizing the importance of considering cancer in unexplained fatigue cases.

## Contribution

This case report adds to the understanding of atypical presentations of metastatic prostate cancer in older adults.

## Key findings

- Fatigue and urinary symptoms in an older man led to the discovery of metastatic prostate cancer.
- The case underscores the importance of considering malignancy in the differential diagnosis of unexplained fatigue.

## Abstract

Fatigue in older adults, though common and nonspecific, may signal serious disease. This report describes an older man whose complaint of fatigue, evaluated with urinary symptoms, revealed metastatic prostate cancer with diffuse bone involvement. This highlights the need to consider malignancy in the differential of unexplained fatigue.
