[Clinical Picture] Metastatic seminoma masquerading as sarcoidosis

A 76-year-old man presented to the haematology clinic at Vancouver General Hospital (Vancouver, BC, Canada) in September, 2022, with fatigue. A full-body MRI showed cervical, intrathoracic, and intraabdominal lymphadenopathy, including an anterior mediastinal mass believed to be a lymph node conglomerate, and bony lesions in the spine, ribs, pelvis, and femur. He had a history of prostate cancer and non-invasive bladder cancer. A neck lymph node core biopsy and EBUS-guided lymph node aspirate showed non-necrotising granulomatous inflammation with no evidence of malignancy.
