Solitary osseous sarcoidosis: a rare reason for pathologic fracture.

Sarcoidosis with osseous involvement as the initial manifestation is rare. Due to lack of other organ involvements, the diagnosis is somehow difficult to establish. We report a case with osseous sarcoidosis as the initial and major manifestation that developed spontaneous bone fracture. Our case emphasizes the importance of histological evidence and exclusion of other diseases i.e. rheumatoid arthritis, before making the diagnosis of osseous sarcoidosis.
