MINOR SALIVARY-GLAND HYALINISATION AND AMYLOIDOSIS IN LOW-GRADE LYMPHOMA OF MALT

Two patients with low-grade lymphoma of mucosa-associated lymphoid tis sue (MALT) arising in primary Sjogren's syndrome developed solitary no dules in their lips. Histologically both lesions showed enlargement an d hyalinisation of single minor salivary glands with acinar atrophy, l oss of most ducts and conversion into almost acellular sclerotic eosin ophilic masses. In one case the lesion was shown to contain an amyloid component. No amyloid was detected in the second case but deposition of collagen and basement membrane and sclerotic neoplasm were excluded .
