MALT lymphoma originating in breast and uvula

A case of marginal zone B cell lymphoma of MALT type arising in the uvula a nd breast is reported. The patient. a 30-year-old woman who delivered a chi ld and lactated in 1997, was suffering from Sjogren syndrome (SS).

Moreover, hormones such as progest erone may have influenced the breast involvement of MALT lymphoma in our ca se.
