Sarcoidosis mimicking metastatic disease: a case report and review of the literature.

Osseous and in particular vertebral sarcoidosis is exceedingly rare and a difficult diagnosis to establish because it may simulate many diseases, including even metastatic malignancy. we present a patient with lesions in bones, lungs and lymph nodes, mimicking the presence of extensive metastatic disease. our case emphasises the importance of histological evidence before the diagnosis of osseous sarcoidosis can be made with confidence.
