Background. Mucosa associated lymphoid tissue (MALT) lymphoma has been note
d to involve the salivary glands in chronic inflammatory conditions such as
Sjogren's syndrome and in HIV infection.
Methods and Results. The authors encountered a patient with bilateral cysti
c changes in the parotid glands which proved to be due to MALT lymphoma. Th
e clinical course, histopathology, and treatment options of MALT lymphoma i
n the salivary gland are discussed in detail.
Conclusion. This malignant entity should be considered in the differential
diagnosis of refractory cystic lesions of the salivary glands. (C) 2001 Joh
