Paraneoplastic movement disorders are rare, autoimmune-mediated, nonmetastatic complications of malignant neoplasms. Common paraneoplastic movement disorders include paraneoplastic chorea, dystonia, cerebellar degeneration, different types of encephalitis, opsoclonus-myoclonus syndrome, stiff person syndrome, and neuromyotonia. Syndromes usually develop before tumor diagnosis, have subacute onset, and are associated with serum or cerebrospinal fluid antibodies. Two types of antibodies can be distinguished: antibodies against nuclear and cytoplasmic neuronal antigens (anti-Hu, anti-Ri, anti-Yo, anti-Ma, anti-CV2/CRMP5, anti-Gephrin, and anti-GABATRAP) and antibodies recently identified against cell surface and synaptic proteins (anti-NMDAR, anti-LGI1, and anti-Caspr2)...

A 36-year-old woman suffering from oral ulcerations, skin rash, and dyspnea was suspected of having paraneoplastic pemphigus. An F-FDG PET/CT was performed to detect the underlying neoplasms and revealed an F-FDG-avid mass in the lower right retroperitoneum. The mucocutaneous lesions and dyspnea were relieved after the tumor excision, and the pathology indicated Castleman disease.

Systemic sclerosis (SSc) is a rare connective tissue disease characterized by three pathogenetic hallmarks: vasculopathy, dysregulation of the immune system, and fibrosis. A particular feature of SSc is the increased frequency of some types of malignancies, namely breast, lung, and hematological malignancies. Moreover, SSc may also be a paraneoplastic disease, again indicating a strong link between cancer and scleroderma. The reason of this association is still unknown; therefore, we aimed at investigating whether particular genetic or epigenetic factors may play a role in promoting cancer development in patients with SSc and whether some features are shared by the two conditions...

A 33-year-old man presented with a 10-day history of bilateral blurred vision on a background of a prodromal influenza-like illness. Ocular Coherence Tomography (OCT) and fundal examination coincided with a diagnosis of atypical central serous retinopathy. The patient's symptoms worsened during follow-up, and he was started on steroids. Subsequent fundal examination revealed yellow deposits in a honeycomb pattern and hard exudates in the perimacular region. Serial OCTs revealed progression of bilateral macular intraretinal and subretinal fluid...

A 70-year-old man was referred to our hospital with exacerbation of diabetes. His blood tests showed elevated levels of serum IgG4 and HbA1c. Computed tomography of the pancreatic body demonstrated a weakly enhanced mass, 2 cm in size, with indistinct borders. Magnetic resonance cholangiopancreatography revealed a narrowing of the main pancreatic duct (MPD) at the pancreatic body, a markedly dilated upstream duct, and a slightly dilated downstream duct. Endoscopic ultrasonography demonstrated an iso-hypoechoic heterogeneous mass, protruding and spreading in the pancreatic duct...

The purpose of this study was to analyse the characteristics of 6 patients managed in a university hospital between 1996 and 2016 for non-islet cell tumor hypoglycemia (NICTH), a form of hypoglycaemia due to the paraneoplastic secretion of IGF-2 or its related substances. RESULTS: Three of these 6 patients (50%), aged over 69 years, including 2 with acromegaloid phenotype, presented with a pleural solitary fibrous tumor (SFT), with median diameter 20 cm (interquartile range, 12.5-20.5) with a low median SUV (3...

TAp73 and p53 are involved in regulating tumor angiogenesis and vasohibin-1 (VASH1) is an anti-angiogenic factor. Whether TAp73 regulates angiogenesis positively or negatively is controversial. The status of P53 may determine the effect of TAp73 on angiogenesis. To the best of our knowledge it has not been previously reported whether TAp73, p53 and VASH1 are coexpressed in lung cancer. We profiled the association between TAp73 and p53 and VASH1 expression in lung adenocarcinoma (LAC) and investigated the function of TAp73 in regulating tumor angiogenesis...

Background: Previous series of bilateral vestibular loss (BVL) identified numerous etiologies, but surprisingly, a cause in a significant number of cases remains unknown. In an effort to understand possible etiology and management strategies, a global effort is currently in progress. Here, I contribute my 10-year experience with both acute and chronic BVL during the 2007-2017 decade. Methods: This is a retrospective review of the charts and EMR of patients diagnosed with BVL in the last 10 years...

Transthyretin-related Familial Amyloid Polyneuropathy (ATTR Amyloidosis, former FAP, here called TTR-FAP) is a rare, progressive autosomal dominant inherited amyloid disease ending fatal within 5 - 15 years after final diagnosis. TTR-FAP is caused by mutations of transthyretin (TTR), which forms amyloid fibrils affecting peripheral and autonomic nerves, the heart and other organs. Due to the phenotypic heterogeneity and partly not specific enough clinical symptoms, diagnosis of TTR-FAP can be complicated...

As with other genitourinary malignancies, a variety of paraneoplastic syndromes have been revealed to occur in patients with prostate cancer. Stauffer's Syndrome is a well-described clinical syndrome which manifests via intrahepatic cholestasis in patients with renal cell carcinoma. Less common is intrahepatic cholestasis occurring in association with prostate cancer. The current case report discusses a 67-year-old man presenting with liver failure secondary to intrahepatic cholestasis co-existing with metastatic prostate adenocarcinoma...

BACKGROUND: Pemphigus has a protracted course and multiple factors influence its prognosis. The objective of this study was to describe the epidemiology and clinical profile of pemphigus patients and to study its influence on treatment end points. METHODS: This was a retrospective chart review done in an Indian tertiary care hospital from December 1991 to December 2013. Patients with less than 3 months' follow up and those who had paraneoplastic pemphigus were excluded...

The paraneoplastic and autoimmune encephalitides are now well-established entities. Detection of neural autoantibodies enables specific diagnoses, provides information on the underlying disease pathophysiology, immunological treatability and the likelihood of a tumor being the underlying cause. This is true for the "high ranking" neural antibodies that have been established in the context of circumscribed clinical images and in consideration of large control groups, have been found in the same way by other laboratories and they respond to immunotherapy...

The objective of this study is to report three cases of paraneoplastic or ectopic Cushing syndrome, which is a rare phenomenon of the adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome. Three cases are reported in respect of clinical presentation, diagnosis and treatment in addition to relevant literature review. The results showed that ectopic ACTH secretion can be associated with different types of neoplasm most common of which are bronchial carcinoid tumors, which are slow-growing, well-differentiated neoplasms with a favorable prognosis and small-cell lung cancer, which are poorly differentiated tumors with a poor outcome...

Anti-N-methyl D-aspartate receptor (NMDAR) encephalitis is a paraneoplastic, immune-mediated encephalopathy with a known association with ovarian teratomas. We present the first case in the UK of a 7-year-old patient presenting with this condition. Having been previously fit and healthy, the patient presented with an acute onset of cognitive disturbances. The initial suspicion was that of an infective encephalopathy; however, the lumbar puncture results were negative. Electroencephalography reported diffuse background slowing, supporting a diagnosis of encephalopathy...

We report a first case of paraneoplastic human chorionic gonadotropin (HCG) production in a dedifferentiated liposarcoma with rhabdosarcomatous differentiation in an 83-year-old man with a retroperitoneal mass, unilateral scrotal enlargement, and a serum HCG level of 843 IU/L. Core biopsy of the retroperitoneal mass revealed rhabdomyosarcoma. Orchiectomy revealed a paratesticular dedifferentiated liposarcoma with rhabdosarcomatous differentiation. Fluorescence in situ hybridization analysis performed on both the retroperitoneal and paratesticular masses revealed amplification of MDM2...

Neuroblastoma is an embryonic tumor of the peripheral sympathetic nervous system. It is the most common extracranial solid tumor of childhood and accounts for up to 15% of all pediatric cancer fatalities. The manifestation of neuroblastoma is variable depending on the location of the tumor and on the presence or absence of paraneoplastic syndromes. The prognosis of neuroblastoma is also highly variable, ranging from spontaneous regression to widespread metastatic disease that is unresponsive to treatment. The age of the patient, stage of disease, histopathologic results, and multiple biologic factors contribute to the presurgical and pretreatment risk stratification of a patient with neuroblastoma...

Paraneoplastic pemphigus (PNP) is a severe autoimmune blistering disease associated with an underlying malignancy, and its prognosis is poor. We herein report the first patient with B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (B-CLL/SLL)-associated PNP successfully treated with the Bruton's tyrosine kinase inhibitor ibrutinib and rituximab. Although his PNP lesions did not improve with ibrutinib monotherapy, the combination of ibrutinib and rituximab was effective against B-CLL/SLL-associated PNP...

Lambert-Eaton myasthenic syndrome (LEMS) is most commonly associated with small cell lung carcinoma, while it is rarely associated with gynecological and breast carcinoma. We herein report a case of LEMS associated with synchronous double cancer, which was a combination of small cell carcinoma of the cervix and breast carcinoma. The early diagnosis and treatment of LEMS are important for achieving a good outcome. The possibility of accompanying paraneoplastic neurological syndrome must be sufficiently considered in gynecology and breast cancer patients...

Solitary fibrous tumor (SFT) is a rare subtype of soft tissue sarcoma (STS). We herein describe a case of late onset of non-islet cell tumor hypoglycemia (NICTH) that was managed via multidisciplinary treatment in a patient with SFT. A 67-year-old man previously diagnosed with SFT 4 years prior to this presentation and treated with several rounds of surgery, presented with massive tumors. Eighteen months following his prescribed chemotherapy, the patient developed hypoglycemia. He was diagnosed with NICTH, after confirming the presence of high molecular weight insulin-like growth factor-2...
