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: 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...

Morvan's syndrome (MoS) is a rare, complex neurological disorder characterized by neuromyotonia, neuropsychiatric features, dysautonomia and neuropathic pain. The majority of MoS cases have a paraneoplastic aetiology, usually occurring prior to the diagnosis of the underlying tumour and showing improvement following its treatment. The present study reports the case of a 35-year-old Caucasian male patient who was diagnosed with stage IVA thymoma. Thymectomy, lung resection, diaphragmatic pleurectomy and pericardio-phrenectomy were performed 6 months after neoadjuvant chemotherapy...

Introduction. Bilateral vocal cord paralysis (BVCP) is a potential medical emergency. The Otolaryngologist plays a crucial role in the diagnosis and management of BVCP and must consider a broad differential diagnosis. We present a rare case of BVCP secondary to anti-Hu paraneoplastic syndrome. Case Presentation. A 58-year-old female presented to an Otolaryngology clinic with a history of progressive hoarseness and dysphagia. Flexible nasolaryngoscopy demonstrated BVCP. Cross-sectional imaging of the brain and vagus nerves was negative...

Paraneoplastic neurological syndromes (PNSs) are rare nervous system dysfunctions in cancer patients, which are primarily observed with small-cell lung cancer, gynecological cancer, and thymoma. We herein present an uncommon case of PNS in an anti-Hu antibody-positive patient with human epidermal growth factor receptor (HER)-2-positive gastric cancer (GC), who developed limbic encephalitis and a worsening cognitive function. Trastuzumab-combined chemotherapy was initiated and appeared to be partially effective for controlling the neurological symptoms and tumor volume...

CTLA4 is an inhibitory regulator of immune responses. Therapeutic CTLA4 blockade enhances T cell responses against cancer and provides striking clinical results against advanced melanoma. However, this therapy is associated with immune-related adverse events. Paraneoplastic neurologic disorders are immune-mediated neurological diseases that develop in the setting of malignancy. The target onconeural antigens are expressed physiologically by neurons, and aberrantly by certain tumour cells. These tumour-associated antigens can be presented to T cells, generating an antigen-specific immune response that leads to autoimmunity within the nervous system...

Patients with Purkinje cell cytoplasmic autoantibody type 2 (PCA-2) and collapsin response-mediator protein-5 (CRMP-5) autoantibody can present with multifocal elements of encephalomyeloneuropathy. Except for an anecdotal report, case descriptions of paraneoplastic small fibre neuropathy are lacking. We report paraneoplastic small fibre neuropathy followed by chorea associated with small cell lung cancer. A man aged 57 years with a 35 pack-year smoking history presented with painless subacute paresthesia and weight fluctuation...

A 55-year-old man presented with oral mucosal ulcers, blackening of both hands, and hyperpigmentation on axillary, anal, and inguinal regions for the last 3 months, which were all progressive. The patient was referred to the oncology department with the diagnosis of acanthosis nigricans for investigation of an underlying malignancy. He was a smoker. A computed tomography scan of thorax revealed enlarged mediastinal lymphadenopathies and a lesion on the left upper lobe. Fine-needle aspiration biopsy of the mediastinal lesion was consistent with squamous cell carcinoma, and biopsies of the skin and oral mucosal lesion also further confirmed the diagnosis of acanthosis nigricans...

Lambert-Eaton myasthenic syndrome (LEMS) is an uncommon autoimmune idiopathic or paraneoplastic syndrome producing antibodies against voltage presynaptic calcium channels. According to previous studies, many patients with LEMS experience remission in both the clinical symptoms of muscle weakness and the electrophysiologic abnormalities after successful treatment of lung SCC. However, some patients might not respond to conventional therapy and eventually require palliative care. Hereby, we reported a LEMS patient with advanced lung malignancy was referred for palliative care...

Delirium in patients with cancer is associated with poor outcomes, but reversible causes need to be ruled out. We report the case of a 59-year-old woman who was presented with behavioural and cognitive changes over 2 weeks. She was non-verbal and combative, requiring involuntary admission and declaration of incompetence to make healthcare treatment decisions. Infectious and metabolic investigations and initial brain imaging were unremarkable. She was diagnosed with limited-stage small cell lung cancer and a paraneoplastic neuropsychiatric syndrome...

BACKGROUND: Membranoproliferative glomerulonephritis is a common pattern of glomerular injury in monoclonal gammopathy, but has only rarely been associated with solid organ tumors, mainly lung, renal, gastric, breast, and prostate. There have been two reported cases of membranoproliferative glomerulonephritis associated with adenocarcinoma of the colon and rectum, although the association may be coincidental. We report a case where nephrotic syndrome due to membranoproliferative glomerulonephritis developed in a patient with colorectal carcinoma and elucidate some of the pathophysiological mechanisms underpinning this presentation...

Paraneoplastic syndromes (PNS) associated with lung cancer are well recognised, are often complex to diagnose, and have minimal evidence to promote nursing and medical management. This paper aims to help guide lung cancer nurses to identify the most common and rarer PNS together with basic clinical management advice to help develop nursing assessments and interventions. The issues regarding the pathway of care at diagnosis together with palliative and supportive care requirements will be addressed and will aim to promote best practice in patients diagnosed with PNS and lung cancer...

Lambert-Eaton syndrome (LES) is a rare immune-mediated disorder characterized by proximal leg weakness, autonomic symptoms and hypoactive tendon reflexes. The paraneoplastic form is associated with small-cell lung cancer in 50-60% of cases, whereas the remaining cases are found in younger adults with a higher likelihood of coexisting autoimmune disease. The early recognition of LES is crucial for improving clinical outcomes but remains a major challenge. In this review, we analyze the clinical characteristics and diagnostic considerations in treating LES through a series of three case studies, one of which showed definitive response to pyridostigmine and corticosteroid combination therapy, followed by spontaneous remission...

Lambert-Eaton myasthenic syndrome (LEMS) is a paraneoplastic syndrome and only 3% of small cell lung carcinoma (SCLC) patients have LEMS. Moreover, the recurrence of SCLC after a disease-free survival (DFS) of more than 10 years is rare. We report a patient who had a recurrence of both SCLC and LEMS after a 13-year DFS period. A 69-year-old man was diagnosed with LEMS and SCLC (cT0N2M0, stage IIIA) 13 years ago. Chemoradiotherapy was performed and a complete response was achieved. With anticancer treatment, the LEMS symptoms was alleviated...

Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e...

Paraneoplastic Cushing's syndrome (CushingPS) caused by bronchopulmonary carcinoid tumors presents a diagnostic challenge for clinicians. The present study reports the case of an 18-year-old male patient presenting with rapid weight gain, polyuria, polydipsia and progressive muscle weakness. Chemical and imaging findings suggested ectopic secretion of adrenocorticotropin. Whole-body (18)fluorine-fluorodeoxyglucose ((18)FDG-PET/CT) positron-emission tomography revealed an increased uptake of (18)FDG-PET/CT in the right middle lung mass and lobar lymph node...

BACKGROUND: Paraneoplastic syndrome generally results from tumor-derived hormones or peptides that cause metabolic derangements. Common metabolic conditions include hyponatremia, hypercalcemia, hypoglycemia, and Cushing's syndrome. Herein, we report a very rare case of tongue carcinoma presenting with leukocytosis and hypercalcemia. CASE PRESENTATION: A 57-year-old man was admitted to our hospital with tongue squamous cell carcinoma (cT4aN0M0, stage IV). He underwent radical resection following preoperative chemoradiotherapy, but locoregional recurrence was detected 2 months after surgery...
