We report the case of a patient presenting with multiple severe electrolyte disturbances who was subsequently found to have small cell lung cancer. Upon further evaluation, she demonstrated three distinct paraneoplastic processes, including the syndrome of inappropriate antidiuretic hormone, Fanconi syndrome, and an inappropriate elevation in fibroblast growth factor-23 (FGF23). The patient underwent one round of chemotherapy, but she was found to have progressive disease. After 36 days of hospitalization, the patient made the decision to enter hospice care and later she expired...

AIM: Doege-Potter syndrome is a rare condition consisting of a mesenchymal tumor, either benign or malignant, accompanied by severe hypoglycemia. The syndrome was first described independently by two American physicians, Karl Walter Doege (1867-1932) and Roy Pilling Potter (1879-1968), in 1930, but it was not before 1988 that it was associated with non-islet cell tumor production of insulin growth factor (IGF) that induces hypoglycemia as a paraneoplastic syndrome. CASE PRESENTATION: We present the case of a 61-year-old woman with severe hypoglycemia that induced seizures...

INTRODUCTION: Immune dysregulation associated encephalopathies present with significant psychiatric manifestations and only a few soft neurological and general systemic features. They are generally resistant to treatment with psychiatric medications. Generalized orthostatic myoclonus and faciobrachial dystonic seizures are mistaken as Creutzfeldt-Jakob disease and subacute sclerosing panencephalitis. PATIENTS AND METHODS: Forty-two patients seen during 2010-2015 and diagnosed as noninfective encephalopathy were analyzed...

Paraneoplastic cerebellar ataxia (PCA) is most frequently observed in gynaecological cancers, small cell lung cancer, breast cancer, Hodgkin's lymphoma, cancer testis or malignant thymoma. In the literature, there is no data related to the effects of PCA during pregnancy or reports on the effects of anaesthesia in patients with PCA. We present management of a pregnant woman with PCA who was suddenly unable to walk with PCA and for whom effective spinal anaesthesia was performed for an elective caesarean section with no complications...

Carcinoid tumors are neuroendocrine tumors that mainly arise in the gastrointestinal tract, lungs, and bronchi. Bronchopulmonary carcinoids have been associated with Cushing syndrome, which results from ectopic adrenocorticotrophic hormone (ACTH) secretion. We report the case of a 65-year-old man, a colonel in the US Air Force, with metastatic bronchopulmonary carcinoid tumors treated on a clinical trial who was hospitalized for complaints of increasing thirst, polydipsia, polyuria, weakness, and visual changes...

Renal cell carcinoma has previously been associated with hypoglycaemia in the setting of non-islet cell tumours, caused by a paraneoplastic phenomenon relating to the production of insulin-like growth factor type II. We present a case of recurrent clear cell renal cell carcinoma, leading to an insulin-mediated paraneoplastic phenomenon causing severe recurrent hypoglycaemia. Hypoglycaemina was managed successfully using diazoxide therapy, in conjunction with pazopanib and radiotherapy to reduce tumour burden...

REVIEW
Grazyna Adamus
Autoantibodies (AAbs) against glycolytic enzymes: aldolase, α-enolase, glyceraldehyde-3-phosphate dehydrogenase, and pyruvate kinase are prevalent in sera of patients with blinding retinal diseases, such as paraneoplastic [cancer-associated retinopathy (CAR)] and non-paraneoplastic autoimmune retinopathies, as well as in many other autoimmune diseases. CAR is a degenerative disease of the retina characterized by sudden vision loss in patients with cancer and serum anti-retinal AAbs. In this review, we discuss the widespread serum presence of anti-glycolytic enzyme AAbs and their significance in autoimmune diseases...

BACKGROUND: Paraneoplastic acral vascular syndrome (PAVS) is a rare phenomenon which is observed in patients with adenocarcinomas and other malignancies. Various potential pathogenic mechanisms such as tumour invasion of sympathetic nerves, hyperviscosity, hypercoagulability, vasoactive tumour-secreted substances, and immunological mechanisms have been suggested. CASE PRESENTATION: We report a 60-year-old Caucasian male attended our hospital with a bulky lymph node mass in the right axilla...

Multiple etiologies should be considered in the differential diagnosis of immunocompromised patients with non-central nervous system cancer and viral infections who develop mutism. Acute cerebellitis, caused by infections or by neurotoxicity resulting from chemotherapy; paraneoplastic cerebellar degeneration; atypical posterior reversible encephalopathy syndrome; and acute disseminated encephalomyelitis may all cause mutism in such patients. This condition warrants prompt recognition and may require treatment with immunotherapy, as it may be an immune-mediated process...

Pemphigus is a group of IgG-mediated autoimmune diseases of stratified squamous epithelia, such as the skin and oral mucosa, in which acantholysis (the loss of cell adhesion) causes blisters and erosions. Pemphigus has three major subtypes: pemphigus vulgaris, pemphigus foliaceus and paraneoplastic pemphigus. IgG autoantibodies are characteristically raised against desmoglein 1 and desmoglein 3, which are cell-cell adhesion molecules found in desmosomes. The sites of blister formation can be physiologically explained by the anti-desmoglein autoantibody profile and tissue-specific expression pattern of desmoglein isoforms...

CASE SUMMARY: Herein we describe an unusual metastatic pattern and paraneoplastic manifestation of a bronchial carcinoma in a cat. An 8 year-old cat presented with a diminished appetite, dysphagia, weight loss, lethargy and coughing. Thoracic radiographs revealed a lung mass. Bronchial carcinoma was diagnosed on the basis of histology and was associated with a lymphoplasmocytic infiltration of the fibrovascular stroma. Biochemistry showed hyperproteinaemia. Serum protein electrophoresis showed a narrow spike in the gamma region...

Keloid is a benign fibroproliferative growths resulting from an overexuberant healing response. A 51-year-old man with a 20-year history of keloid formation presented with a 1-year history of unexplained progressive weakness of both lower limbs. He was clinically suspected of having paraneoplastic neurologic syndrome. FDG PET/CT was performed to exclude underlying malignancy. FDG PET/CT revealed a giant FDG-avid keloid in the anterior chest wall without any other abnormal FDG uptake in the body. We emphasize that a benign FDG-avid keloid should be considered in the differential diagnosis of FDG-avid cutaneous lesions on PET/CT...

An imaging case is presented on a patient referred to our department for an (18)F-FDG-PET/CT, as a paraneoplastic syndrome was suspected due to his clinical situation. He had a history of acute myeloid leukemia (AML) treated two years earlier, with sustained complete remission to date. (18)F-FDG-PET/CT findings revealed hypermetabolism in almost all nerve roots, suggesting meningeal spread, consistent with the subsequent MRI findings. Cerebrospinal fluid (CSF) findings confirmed a leptomeningeal reactivation of AML...

BACKGROUND: Nephrotic-range proteinuria as a paraneoplastic syndrome (PNS) is an exceptional presentation, especially in children. It is usually associated with hematologic malignancies. Solid tumors are very rare causes of proteinuria. CASE-DIAGNOSIS/TREATMENT: We present the case of a 7-year-old boy with an extremely rare atypical thymic carcinoid accompanied by nephrotic-range proteinuria as PNS. The kidney biopsy was consistent with minimal change disease (MCD)...
