We present an atypical case of peripheral nervous system (PNS) involve
ment in Sjogren's syndrome in a 63 year-old woman. Symptoms of an entr
apment neuropathy were the first manifestation of the systemic disease
and they mere subsequently coupled to those of a mononeuritis multipl
ex. Clinical and laboratory signs for the diagnosis of Sjogren's syndr
ome became subsequently overt. The mononeuritis multiplex remained cli
nically limited to the upper limbs and characterized by unusually seve
re motor symptoms which progressed up to the development of a final co
mplete deplegia. By contrast, sensory symptoms at the upper limbs rema
ined mild over the entire course of the disease and the lower limbs re
vealed a subclinical sensory-motor damage only during the late stage.
