title: [Sarcoidosis as a mimicry of haemangiotic carcinomatosis].
abstract: The radiologic work-up of a 67-year-old female patient for dyspnea revealed micronodular infiltrates in both lungs, which in combination with enlarged mediastinal and abdominal lymph-nodes were highly suspicious of sarcoidosis stage II. A bronchoscopic examination including transbronchial biopsy in another hospital was not diagnostic, so the patient was referred to us for surgical lung biopsy. A specimen from the right middle lobe showed massive haemangiotic carcinomatosis of a clear-cell carcinoma. The pathologist--without knowing the history of the patient--discussed a renal-cell carcinoma as potential primary malignancy, which could easily be confirmed as the patient had a tumor-nephrectomy two years ago.
