Sarcoidosis mimicking metastatic seminoma

    Research output: Contribution to journalReview articlepeer-review


    A 42-year-old man had an orchidectomy following detection of a right testicular mass which was demonstrated histologically to be seminoma. CT scanning revealed small volume peribronchial lymphadenopathy. This was demonstrated to show intense F18-FDG uptake on a subsequent PET scan and the report suggested metastatic disease. Transbronchial biopsy revealed sarcoidosis, which was confirmed by the subsequent clinical course of the patient. This patient is a further example of the previously documented relationship between sarcoidosis and testicular cancer. PET cannot distinguish between the benign inflammatory process of sarcoidosis and metastatic malignancy. The use of chemotherapy was avoided in this case following accurate determination of the underlying pathology.
