Qu Jiang, Bin Hong Zhang
RATIONALE: Paraneoplastic pemphigus (PNP) is an autoimmune syndrome associated with neoplasms. The treatment approach principally includes suppressing the immunity, but its therapeutic effect is not satisfying. PATIENT CONCERNS: We report a case of paraneoplastic pemphigus linked to chronic lymphocytic leukemia in a 63-year-old man. DIAGNOSES: At first, the patient was diagnosed with pityriasis rose caused by a viral infection. Biopsies for histology and immunofluorescence showed PNP, was treated with immunosuppressive and antiinfective therapy...

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) has various causes including central nervous system disorders, pulmonary and endocrine diseases, paraneoplastic syndromes, and use of certain drugs. SIADH induced by chemotherapy with irinotecan-cisplatin is not a common complication. Here, we review a case of SIADH after treatment with irinotecan-cisplatin. A 45-year-old woman received adjuvant chemotherapy (paclitaxel-carboplatin) for ovarian clear cell carcinoma, but the cancer recurred within 9 months of chemotherapy...

The opsoclonus-myoclonus ataxia syndrome (OMAS) also called "Kinsbourne syndrome" or "dancing eye syndrome" is a rare but serious disorder characterized by opsoclonus, myoclonus, and ataxia, along with extreme irritability and behavioural changes. Data on its epidemiology, clinical features, and outcome are limited worldwide. The aim of the study was to evaluate the clinical profile and outcome of children with OMAS. A retrospective data of all children presented to Pediatric oncology clinic with a diagnosis of opsoclonus-myoclonus from 2013 to 2016 were collected...

Three cases of metabolic bone disease in the setting of metastatic neuroendocrine tumor (NET) are illustrated with associated etiopathologies.  One of these cases harbored mixed lesions in the form of vertebral metastasis (biopsy proven) while the other skeletal lesions were caused due to metabolic bone disease related to multiple parathyroid adenomas. While the metastatic lesion was positive on 68Ga-DOTATATE positron emission tomography-computed tomography (PET-CT), the lesions of metabolic bone disease were negative and the 18F-fluoride PET-CT demonstrated the features of metabolic bone scan...

Dermatomyositis is a myopathic or amyopathic autoimmune connective tissue disease that presents with classic dermatologic findings ranging from: poikilodermatous photosensitivity (shawl sign), eyelid edema and violaceous-pigmentation (heliotrope sign), lichenoid eruptions on the knuckles and elbows (Gottron's sign), periungual telangiectasias, and ragged cuticles (Samitz sign). Up to 30 percent of adult-onset cases of dermatomyositis may represent a paraneoplastic syndrome warranting a thorough work-up for malignancy...

The production of autoantibodies to self antigens is dependent on the failure of immune tolerance. Cancer cells express antigens which elicit a spontaneous immune response in cancer patients. The repertoire of autoantibodies found in cancer patients partly covers that of patients with autoimmune diseases. Biological activities of autoantibodies to self antigens may induce paraneoplastic syndromes which reflect the attempt of cancer patients to counteract tumor growth. Autoantibodies with similar specificities may have different effects in cancer and autoimmune disease patients due to different immunological microenvironments...

BACKGROUND: Neuroinflammation is associated with a wide range of neurodegenerative disorders, however the specific contribution to individual disease pathogenesis and selective neuronal cell death is not well understood. Inflammatory cerebellar ataxias are neurodegenerative diseases occurring in various autoimmune/inflammatory conditions, e.g. paraneoplastic syndromes. However, how inflammatory insults can cause selective cerebellar neurodegeneration in the context of these diseases remains open, and appropriate animal models are lacking...

BACKGROUND: Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by renal phosphate wasting, hypophosphatemia, reduction of 1,25-dihydroxyl vitamin D, and bone calcification disorders. Tumors associated with TIO are typically phosphaturic mesenchymal tumors that are bone and soft tissue origin and often present as a solitary tumor. The high production of fibroblast growth factor 23 (FGF23) by the tumor is believed to be the causative factor responsible for the impaired renal tubular phosphate reabsorption, hypophosphatemia and osteomalacia...

BACKGROUND: The chemokine CXCL-13 is a potential intrathecal biomarker for neuroborreliosis (NB). According to the literature the sensitivity of CXCL-13 in the diagnostics of NB varies between 88% and 100% and the specificity between 63% and 99.7%. The objective of this study was to analyze the sensitivity and specificity of CXCL-13 in the diagnosis of NB in an endemic area of Borrelia burgdorferi. MATERIAL AND METHODS: In a retrospective analysis of data from August 2014 to August 2016, 63 patients with clinically suspected NB were identified...

The association between cancer and immune-mediated rheumatic conditions is controversial, especially as far as polymyalgia rheumatica (PMR) is concerned. Furthermore, no clinical feature has been shown to be suggestive of a paraneoplastic rheumatic syndrome. With the present study, we aim to address both these issues. The study population comprised N = 1750 patients, including N = 100 with PMR, who attended our tertiary immuno-rheumatology clinic between January 1, 2005 and November 30, 2012. A rheumatic disease was deemed paraneoplastic if cancer had been diagnosed in the 2 years preceding or following its onset...

Hypercalcemia of malignancy is a common complication of certain types of cancers. No standard therapies exist for the treatment of hypercalcemia secondary to paraneoplastic syndromes that result in the long-term control of serum calcium levels. We report a case of metastatic breast cancer with parathyroid hormone-related protein associated with hypercalcemia of malignancy that was treated with transarterial embolization of the hepatic metastatic lesions.

Thymic tumors are rare mediastinal tumors that can present with a wide variety of symptoms. They can cause distant manifestations and are frequently associated with paraneoplastic syndromes. In our case, we describe the evolution of a 68-year-old male whose first manifestation was thrombosis of the inferior vena cava and renal veins. Thrombosis of large abdominal veins is rare, especially without being associated with any other comorbidity or risk factors.

REVIEW
Attila Zalatnai, Eszter Perjési, Eszter Galambos
When 150 years ago Armand Trousseau proposed that some thrombotic events might be the first sign of concealed visceral malignancies, these findings seemed to be just of anecdotal interest. Since then, however, we have learned that adenocarcinomas, including pancreatic cancers could be associated with a wide spectrum of paraneoplastic syndromes. They may precede the detection of the tumor, may occur simultaneously or may develop during its progression. Due to various hematologic, endocrine, cutaneous, articular, neuromuscular, renal or even psychiatric syndromes, their correct interpretation is intriguing, and because their early signs are not necessarily recognized first by oncologists, the paraneoplastic syndromes pose a diagnostic challenge...

Anti-N-methyl-d-aspartate receptor (NMDAR) limbic encephalitis is the most common form of paraneoplastic encephalitis that is associated with teratomas. Because tumor removal leads to better clinical outcomes, it is essential to reveal the location of the teratomas. This is the first reported case of anti-NMDAR encephalitis associated with teratoma of the fallopian tube. Salpingo-oophorectomy improved neurological symptoms and immunohistochemical examinations indicated the expression of NMDAR on neuroglial cells within the fallopian tube teratoma...

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) is a paraneoplastic syndrome driven by plasma cell dyscrasias. We report a patient with novel initial manifestation of polyneuropathy, which was considered due to Sjögren's syndrome but with poor response to methylprednisolone (120 mg/d) and intravenous immunoglobulin (IVIg). Further investigation by imaging tests and following biopsy eventually confirmed the diagnosis of POEMS syndrome secondary to solitary plasmocytoma...
