Sarcoidosis can mimic testicular cancer with lymph node metastasis. Histological confirmation is crucial before starting cancer treatment to avoid misdiagnosis.

Area of Science:

  • Oncology
  • Immunology
  • Pathology

Background:

  • Sarcoidosis is a multisystem inflammatory disease characterized by non-caseating granulomas.
  • Testicular tumors and metastatic spread to para-aortic lymph nodes are typically associated with malignancy.

Observation:

  • A 33-year-old man presented with clinical signs suggestive of a testicular tumor and metastatic disease to para-aortic lymph nodes.
  • Histological examination revealed granulomatous changes in the testis and lymph nodes.
  • The patient had a positive Kveim test.

Findings:

  • The patient was diagnosed with sarcoidosis, presenting atypically as a testicular tumor with metastatic spread.
  • The Kveim test confirmed sarcoidosis.

Implications:
