Summary
A testicular tumor diagnosis led to surgery for a scrotal mass. However, histopathology revealed localized polyarteritis nodosa affecting the epididymis, not a tumor.
Area of Science:
- Urology
- Pathology
- Rheumatology
Background:
- Scrotal masses can present diagnostic challenges.
- Testicular tumors are a primary concern for scrotal masses.
Observation:
- A 31-year-old man presented with a large, firm left scrotal mass.
- The mass obscured the distinction between the testis and epididymis.
- Surgical intervention was performed under the presumptive diagnosis of a testicular tumor.
Findings:
- Histopathological examination revealed distinct arteritis within the epididymis.
- The patient had no signs of systemic illness or abnormal serological markers.
- The final diagnosis was localized polyarteritis nodosa.
Implications:
- This case highlights the importance of thorough histopathological analysis in scrotal masses.
- Localized polyarteritis nodosa can mimic testicular tumors.
- Accurate diagnosis is crucial for appropriate management of scrotal pathology.
