[The value of biopsy of the accessory labial salivary glands for the diagnosis of amylosis].
Diagnosis of amyloidosis depends on the demonstration of amyloid deposits in biopsies using specific stains. Recently, in addition to classical biopsies (kidney, liver, gum, skin, rectal mucosa), labial salivary gland biopsy has been recommended as safe diagnostic method. In our recruitment, it allowed the fortuitous discovery of amyloidosis in three patients suffering from rheumatoid polyarthritis or spondylarthritis. In five other patients (2 cases of familial amyloidosis, 1 dysglobulinemia, 2 primary cardiac amyloidosis), biopsy was performed for systematic search of amyloidosis. In five of these eight cases, a sicca syndrome was associated with the salivary deposits. These deposits were stained with congo red viewed in polarized light and with T thioflavine. Besides, Wright's method allowed to know the AL or AA type of amyloidosis and thus to guide the treatment. On the whole, labial salivary gland biopsy is a highly sensitive method for diagnosis of primary and secondary amyloidosis.
