[Role of biopsy of the accessory salivary glands in Löfgren's syndrome and other forms of sarcoidosis].
The diagnosis of sarcoidosis requires histopathological analysis. Easy accessible site of biopsy is seldom. A systematic labial salivary gland biopsy was performed in 62 suspected sarcoidosis: 22 patients with Löfgren syndrome (group I), and 40 patients with systemic sarcoidosis (group II). Systematic bronchial biopsy was performed in eight patients of group I and ten patients of group II. If systematic biopsies were negative, direct biopsies were performed (lymph node, skin, kidney, liver). In group I, 8/22 labial salivary gland biopsies and 1/8 bronchial biopsies were positive; in group II, 17/40 labial salivary gland biopsies and 5/10 bronchial biopsies were positive. In the other patients, direct biopsies were positive: 27 lymph nodes, eight skin, eight hepatic, four kidney biopsies. In conclusion, labial salivary gland biopsy (even in the absence of sicca syndrome) is more reliable than systematic bronchial biopsies, particularly in Löfgren syndrome and may avoid in 30 to 50% of the cases more aggressive and dangerous biopsies such as liver, kidney or deep lymph nodes biopsies.
