Primary intraoral sarcoidosis.

A case of sarcoidosis manifesting primarily in the oral cavity has been documented and clinicopathological findings are discussed. The diagnosis of sarcoidosis can nearly always be established by an assessment of the clinical picture in combination with the histologic features of an adequate biopsy specimen. The Kveim test is a useful tool in clinical diagnosis, but is not always positive in patients with sarcoidosis. The clinician should also be aware that false positives can occur. Scalene node biopsy can also be a useful diagnostic adjunct. The current case emphasizes that biopsy of an intraoral lesion, scalene node biopsy, and Kveim testing are useful in establishing a diagnosis of sarcoidosis.
