Association of polyarthritis, subcutaneous nodules, and pancreatic disease.

A patient with nodular liquefying panniculitis, polyarthritis and an occult pancreatic neoplasm is described. The skin lesion was initially mistaken for erythema nodosum. Subcutaneous and synovial fluids demonstrated similar negatively birefringent, rectangular particles, lying in between fat globules. Serum lipase,although continuously elevated, did not fluctuate with disease activity. Biochemical evidence of lipolysis in either the synovial fluid or serum was not demonstrable. Immunologic mechanisms appeared not to be involved in the pathogensis of the panniculitis or the arthritis.

Diagnosis of sarcoidosis by lip biopsy of minor salivary glands.

In two patients with bilateral parotid gland swelling of unknown etiology the diagnosis of sarcoidosis was established by lip biopsy of the minor salivary glands. This simple, innocuous biopsy procedure may prove useful in tissue documentation of sarcoidosis.

Immunologic characterization of the mononuclear cell infiltrates in rheumatoid synovia, in rheumatoid nodules, and in lip biopsies from patients with Sjögren's syndrome.

Two subcutaneous rheumatoid nodules and 8 rheumatoid synovia from patients with rheumatoid arthritis (RA); and 2 parotid glands, 1 "pseudolymphoma," and 6 lip biopsies from patients with Sjogren's syndrome (SS) were studied to identify mononuclear cells. The palisading mononuclear cells in subcutaneous nodules had a surface membrane receptor for complement. B lymphocytes surrounded by larger numbers of non-B lymphocytes were found in RA synovium and between salivary ducts of SS lip biopsies. A "pseudolymphoma" obtained from a patient with SS consisted primarily of B lymphocytes. The predominant mononuclear cell in rheumatoid synovia and salivary glands in patients with RA and SS do not have surface membrane receptors from complement and are thus probably T lymphocytes or null cells.
