BACKGROUND Clinical presentations of paraneoplastic syndromes in neuroblastoma may multiply. Review of the clinical data and the literature on this syndrome may help in the diagnosis of neuroblastoma. OBJECTIVES In order to make more accurate diagnosis, we reviewed the clinical data and the literature on this syndrome. PATIENTS AND METHODS Between April 2007 and April 2012, 68 children were...

The paraneoplastic disorders of the nervous system are clinicopathologic syndromes that occur in association with systemic cancer. Dysfunction of any part of the nervous system or its effector organs may be produced by a paraneoplastic process. The temporal relationship between the onset of a paraneoplastic syndrome and the diagnosis of the associate cancer varies. Most of the paraneoplastic sy...

Paraneoplastic syndromes of hepatocellular carcinoma (HCC) are not uncommon. However, the prognosis is poor and follow-up and improvement of paraneoplastic syndromes with treatment have been reported rarely. We report a successful case in an aged man of a massive HCC with paraneoplastic syndrome, treated by combined intraarterial chemotherapy and hepatic resection. Paraneoplastic syndrome (eryt...

A paraneoplastic syndrome is defined as a group of symptoms that develop when substances released by some cancer cells disrupt the normal function of the surrounding cells and tissue. Paraneoplastic renal syndromes are diseases that indirectly compromise tubular and glomerular function by electrolyte imbalance, hormone-producing tumors or deposition of antigen-antibody complexes in the glomerul...

BACKGROUND Paraneoplastic neurological disorders associated with anti-Ri-antibodies, which are typically present with opsoclonus-myoclonus-ataxia. Most cases with anti-Ri-antibodyassociated paraneoplastic syndrome due to breast cancer occur in women - its occurrence in men is extremely rare. CASE REPORT We present herein the case of a male patient with breast cancer who had atypical anti-Ri-a...

Introduction: Paraneoplastic neurological syndrome is a rare complication of different types of cancer. Non-small cell neuro-endocrine lung cancer is very rare and there are few descriptions of paraneoplastic syndrome in patients with such types of cancer. Paraneoplastic movement disorders, among them chorea, have an exceptionally rare occurrence. Clinical presentation: A 64-year-old woman pres...

Paraneoplastic syndromes rarely affect patients with head and neck cancer. Four patients with different histological types of head and neck cancer are presented in which the primary malignancy was preceded and/or accompanied by a paraneoplastic syndrome. In the first patient erythrodermia preceded the diagnosis of a nasopharyngeal carcinoma. The second patient presented with a B cell lymphoma o...

Neurologic symptoms secondary to a paraneoplastic syndrome may be the presenting manifestation of a previously undiagnosed cancer, and alertness to these syndromes may provide an opportunity for early detection and treatment of a cancer. Paraneoplastic weakness is a rare manifestation of renal cell carcinoma and may present with variable electrophysiological features. We present a case of a pat...

Paraneoplastic syndromes are most often diagnosed in the setting of a known malignancy. It is not uncommon for a paraneoplastic disorder to develop before a cancer is identified. While syndrome of cerebellar degeneration has been identified as a paraneoplastic manifestation of Hodgkin's lymphoma, thymoma, lung and breast cancer, ovarian and testicular tumors, melanoma, renal cell carcinoma, fol...
