## Contribution

This case report adds to the understanding of atypical clinical presentations of testicular seminoma.

## Key findings

- Testicular seminoma was diagnosed alongside severe bilateral hydronephrosis.
- The report emphasizes the need for clinicians to consider rare presentations of testicular cancer.

## Abstract

Testicular germ cell tumors are very common among young men. Most cases are diagnosed at early stages. However, in some instances, the patient may present with metastasis along with associated symptoms. Complaints after testicular cancer metastasis are diverse and vague. Consequently, it is important for clinicians to be familiar with various forms of presentation seen in testicular cancers. Here, we report a case of a 44-year-old patient who presented to the hospital with complaints of abdominal pain, testicular swelling, and bilateral lower extremity edema. This patient was subsequently diagnosed with testicular seminoma and severe bilateral hydronephrosis. Oncology and Urology were consulted for further management. In this report, we review this rare case and discuss different ways testicular seminoma cases could present clinically.
