The incidence and prevalence of paraneoplastic glomerulopathy, especially associated with carcinoma, are a matter of debate and the causal link between cancer and glomerular diseases remains unclear. The aim of this study was to evaluate renal biopsies of selected bitches with spontaneous mammary gland carcinoma. We hypothesized that dogs with mammary carcinomas would show histologic evidence of glomerular pathology. A prospective study was performed in dogs with naturally occurring mammary carcinoma that were undergoing tumor resection and ovariohysterectomy...

This study aims to characterize myositis-specific antibodies in a well-defined cohort of patients with idiopathic inflammatory myopathy and to determine their association with cancer. Sera from 40 patients with polymyositis, dermatomyositis, and controls were tested by protein and RNA immunoprecipitation to detect autoantibodies, and immunoprecipitation-Western blot was used for anti-MJ/NXP-2, anti-MDA5, and anti-TIF1γ/α identification. Medical records were re-evaluated with specific focus on cancer. Anti-MJ/NXP-2 and anti-TIF1γ/α were the most common antibodies in dermatomyositis...

INTRODUCTION: Autoimmune disorders have been documented in solid tumors and malignant hematological disorders. They are very common and well studied in lymphomas which are associated with immune imbalance. They are less common in solid tumors and are categorized as paraneoplastic syndromes with unclear pathogenesis. AIM: The aim of the present study was to find the frequency of autoimmune phenomena in solid tumors of various origin, location and status of the tumor...

Paraneoplastic optic neuropathy (PON) is a rare cause of vision loss usually associated with small cell lung cancer. Patients with this condition usually test positive for anti-collapsin response mediating protein-5 (CRMP-5). We describe a case of a 57-year-old woman with bilateral vision loss with the characteristic features of CRMP-5 PON including bilateral optic disc edema and vitreous cells. However, she was negative for anti-CRMP-5 including a negative Western blot on two occasions, but positive for Purkinje Cell Antibody (PCA)-2...

OBJECTIVE: Association between cancer and systemic sclerosis (SSc) has been described. However, paraneoplastic SSc is not well known. The aim of this article is to describe cases of paraneoplastic systemic sclerosis and to compare them to other cases of the literature, to find characteristics that can make suspect a paraneoplastic mechanism when SSc is diagnosed. METHODS: We retrospectively analyzed patients, in our department who, over the last 15 years, presented with Raynaud's phenomenon with a diagnosis of SSc (including cancer during the period of SSc)...

OBJECTIVE: Raynaud phenomenon is a vasospastic disorder affecting the hands and feet, and the efficacies of traditional treatments, such as pharmacological therapies and sympathectomy, are not uniform. Patients with paraneoplastic Raynaud phenomenon do not benefit from the traditional treatments. The use of botulinum toxin type A (BTX-A) for Raynaud phenomenon has been reported for several years; however, there are few reports regarding botulinum toxin type A in the treatment of paraneoplastic Raynaud phenomenon...

Renal cell carcinoma (RCC) comprises 2‑3% of all malignant tumors in adults. Many studies have established the key roles of smoking, hypertension and other components of metabolic syndrome in the occurrence of RCC. Diabetes mellitus (DM), one of the main consequences of metabolic syndrome, appears much more often in patients with RCC. The prognosis for patients suffering from both diabetes and RCC is worse than for those with kidney cancer only. Diabetes is linked to higher rate of recurrence and a greater number of distant metastases...

Elderly patients are more susceptible to the development of autoimmune blistering disorders such as bullous pemphigoid, mucous membrane pemphigoid, epidermolysis bullosa acquisita, and paraneoplastic pemphigus. This article focuses on the clinical aspects of the aforementioned autoimmune blistering diseases and highlights the important factors involved in treating elderly patients. It is essential for clinicians to offer individualized treatment plans for these patients to optimize outcomes, as elderly patients often have multiple co-morbidities, polypharmacy, and suboptimal socioeconomic status that can adversely influence adequate compliance...

Paraneoplastic syndromes are a heterogeneous group of malignant diseases caused by events which involve endocrine, immune and metabolic aspects and whose symptoms vary according to the substance produced and the primary tumor. Hypercalcemia is a frequent complication in cancer patients. Prognosis of cancer patients with hypercalcemia is usually poor. A factor called parathyroid hormone related peptide, whose actions are similar to those of the parathyroid hormone, is thought to be the most common cause of malignancy associated hypercalcemia...

Paraneoplastic pemphigus (PNP) is a fatal autoimmune blistering disease associated with an underlying malignancy. It is a newly recognized blistering disease, which was first recognized in 1990 by Dr Anhalt who described an atypical pemphigus with associated neoplasia. In 2001, Nguyen proposed the term paraneoplastic autoimmune multiorgan syndrome because of the recognition that the condition affects multiple organ systems. PNP presents most frequently between 45 and 70 years old, but it also occurs in children and adolescents...

Bazex syndrome is a rare paraneoplastic dermatosis. The underlying malignancy frequently is squamous cell carcinoma of the upper aerodigestive tract or cervical lymph nodes from an unknown primary site. We report a 63-year-old man with squamous cell carcinoma of cervical lymph nodes from an unknown primary site. He developed a mass on the right side of his neck, cutaneous lesions diagnosed as Bazex syndrome, hypoalbuminemia, and severe ascites. Right neck dissection was performed. After neck dissection, not only the cutaneous lesions, but also the severe hypoalbuminemia and severe ascites were improved...

BACKGROUND: Conventional magnetic resonance imaging (MRI) is a highly valuable tool for full assessment of the extent of bilateral symmetrical diffuse inflammatory myopathy, owing to its high sensitivity in the detection of edema which correlates with, and sometimes precedes, clinical findings. PURPOSE: To evaluate the use of whole-body (WB)-MRI in characterization and full assessment of the extent and distribution of diffuse inflammatory myopathy. MATERIAL AND METHODS: A prospective study on 15 patients presenting with clinical evidence of inflammatory myopathy...

Opsoclonus-myoclonus-ataxia (OMA) syndrome typically presents with chaotic eye movements and myoclonus with some patients exhibiting ataxia and behavioural disturbances. The pathogenesis may be inflammatory with an infectious or paraneoplastic trigger. We present a 13-year-old HIV-infected girl who was initially started on highly active antiretroviral therapy (HAART) in March 2013 with a CD4 count of 79 cells/cumm. Initially, the patient did not comply with treatment, resulting in a CD4+ count of 77 cells/mm(3) in November 2015 and prompting a new HAART scheme comprising lamivudine, tenofovir and ritonavir-boosted atazanavir...
