Neuromyelitis optica (NMO), or Devic's syndrome, is an autoimmune central nervous system demyelinating disorder primarily affecting the spinal cord and the optic nerves. It is characterized by the presence of NMO antibodies, alongside clinical and radiological findings. NMO and NMO-spectrum disorders (NMO-SD) have been reported in autoimmune disorders, and are infrequently described as a parane...

This is the first case of distant metastases which may have manifested with a paraneoplastic syndrome. CASE DESCRIPTION A 52-year-old white male patient was diagnosed with distant metastases to the bones and liver 11 and 12 years...

Stiff-person syndrome is a rare neurological disorder characterized by stiffness of skeletal muscles with superimposed spasms. The syndrome is a putative autoimmune disease occurring as an idiopathic or paraneoplastic condition. It is often associated with antibodies to glutamic acid decarboxylase (GAD) or, less commonly, to the 128 kD synaptic protein later amphiphysin (AMPH) and few other aut...

Stauffer syndrome is characterized by abnormal liver function tests, hepato-splenomegaly, histologic changes consistent with non-specific hepatitis, and recovery of these abnormalities after nephrectomy, in patients with RCC. Few cases have been described with paraneoplastic cholestatic jaundance of RCC in the literature. We report a case of a female patient presenting with advanced renal cell ...

We analyzed the features of opsoclonus syndrome as a manifestation of post viral encephalopathy in 3 patients (one child and 2 adults). This is the first report of opsoclonus-myoclonus syndrome in the Arabian Peninsula. Symptoms appeared a few days after a viral-like illness in all patients. We excluded the possibility of paraneoplastic syndrome as investigations were carried out and follow-up ...

BACKGROUND Paraneoplastic neurologic syndrome (PNS) represents the remote effects of cancer on the nervous system. Diagnostic criteria for the syndrome were published by the PNS Euronetwork and form the basis of a database to collect standardized clinical data from patients with PNS. OBJECTIVES To analyze various types of PNS, frequent tumor and antibody associations, clinical characteristics...
