Progressive systemic sclerosis (PSS) is a multi-systemic disorder characterized by abundant fibrosis of the skin, blood vessels, and visceral organs. But it rarely affects the peripheral nervous system. We report a 36-year-old man of painful trigeminal neuropathy as a complication of PSS. He was referred from Rheumatology for the evaluation of abruptly developed bilateral facial pain. He had facial hyperesthesia and paresthesia on neurologic examinations. In the blink reflex, ipsilateral and contralateral R1 and R2 responses were not detected during bilateral supraorbital stimulation. But normal latency and CMAP amplitude of facial NCV were found. Under the impression of trigeminal neuropathy caused by PSS, steroid therapy was tried, and his clinical symptoms and electrophysiologic findings were improved. PSS could be the cause of the painful trigeminal neuropathy.
Key words: Progressive systemic sclerosis, Painful trigeminal neuropathy, Blink reflex
