title: Non-caseating granulomas in patients with hematologic malignancies. A report of three cases.
abstract: Sarcoidosis or sarcoid-like lesions occurred in three patients with hematologic malignancies. In one patient, an overlap syndrome sarcoidosis/polycythemia vera was the most probable diagnosis. In the other two cases, the granulomas were probably secondary to myelofibrosis and Waldenström's disease, respectively. Recent epidemiological studies have failed to show a causal relationship between sarcoidosis and malignancy. The co-existence of sarcoidosis and malignancy is probably fortuitous, but non-caseating granulomas may occur secondary to malignant diseases.
