Aims: Lung cancer is the most common malignancy throughout the world. Nonsmall cell lung cancer (NSCLC) is the most common type, and squamous cell type is most common in India. Mostly, patients present with chest-related symptoms and signs. Isolated skeletal muscle metastasis (ISMM) is rarely seen. The aim was to see muscle metastasis and its prognosis. Materials and Methods: We are presenting our data of 8 years about this common malignancy with relation to muscle metastasis, either alone or with other system metastasis...

INTRODUCTION: The role of autoimmune responses against central nervous system (CNS) antigens in encephalitis presenting with non-classified neurologic or psychiatric symptoms has been appreciated in the past decade. Paraneoplastic limbic encephalitis has a poor prognosis and is most commonly associated with lung, ovarium, and testicular neoplasms, leading to immune reactions against intracellular antigens (anti-Hu/ANNA1, anti-Ri/ANNA2, anti-CV2/CRMP5 and anti-Ma2/Ta). In contrast, the recently described autoimmune encephalitis subtypes present with a broad spectrum of symptoms, respond to autoimmune therapies well and usually associate with autoantibodies against neuronal cell surface receptors (NMDAR, GABABR, AMPAR) or synaptic proteins (LGI1, CASPR2)...

A 61-year-old woman who had smoked for 40 years developed subacute dizziness, ataxic gait, opsoclonus, and right visual impairment. She had right optic disc swelling and optic nerve gadolinium enhancement on magnetic resonance imaging. She had small-cell lung cancer (SCLC), with CV2/collapsin response mediator protein (CRMP) 5 and HuD antibodies in her serum and cerebrospinal fluid. She was diagnosed with paraneoplastic optic neuropathy (PON) accompanied by paraneoplastic opsoclonus-ataxia syndrome. Her symptoms improved after removing the SCLC...

Neuromyelitis optic spectrum disorders are demyelinating conditions that are typically idiopathic, though various case reports have demonstrated an association with malignancy. We present the case of a 64year old woman with NMOSD in the setting of small cell lung cancer. She had longitudinally extensive transverse myelitis and left eye optic neuritis; aquaporin-4 antibodies were elevated. Biopsy of mediastinal adenopathy was positive for SCLC. Malignancy should be considered in any patient with an atypical presentation of NMOSD, or who does not respond to traditional therapies...

In the absence of screening, most patients with lung cancer are not diagnosed until later stages, when the prognosis is poor. The most common symptoms are cough and dyspnea, but the most specific symptom is hemoptysis. Digital clubbing, though rare, is highly predictive of lung cancer. Symptoms can be caused by the local tumor, intrathoracic spread, distant metastases, or paraneoplastic syndromes. Clinicians should suspect lung cancer in symptomatic patients with risk factors. The initial study should be chest x-ray, but if results are negative and suspicion remains, the clinician should obtain a computed tomography scan with contrast...

Tumours may produce growth factors and cytokines responsible for signs and symptoms distant to the primary or metastatic site. This may be the first sign of a malignancy and its recognition may be critical for early cancer detection. Moreover, proper diagnosis spares the patient of extensive and expensive search for an alternate cause of the neurological dysfunction. In neurological paraneoplastic syndromes like Lambert Eaton Myasthenic syndrome associated with small cell lung cancer, evidence of autoimmunity against presynaptic neuro-muscular junction by anti voltage gated calcium channel anti bodies is well documented...

BACKGROUND: Gamma-aminobutyric acid-B receptor autoantibodies are becoming an increasingly recognized contributor to the spectrum of autoimmune limbic encephalitis. They are classically associated with seizures and behavioral disturbance, and may coexist with other autoantibodies. Many are paraneoplastic, most commonly associated with small cell lung cancer. Until now there have been no reports of cardiac dysrhythmias in these patients. CASE PRESENTATION: A 65-year-old Caucasian man presented with multiple seizures, dysarthria and behavioral disturbance of unclear etiology, with associated asystolic cardiac arrest...

A 50-year-old man with lung adenocarcinoma (c-T1aN2M1b) experienced reddish purpura mainly on the lower legs after receiving 12 cycles of second-line chemotherapy with docetaxel. There was tumor enlargement on computed tomography performed to assess the therapeutic response, so paraneoplastic IgA vasculitis was considered. IgA vasculitis was diagnosed based on a biopsy of the skin lesion and histology of an upper gastrointestinal hemorrhagic mucosal erosion. As IgA vasculitis can lead to serious gastrointestinal or systemic complications, IgA vasculitis should be considered as a differential diagnosis for rashes in patients with malignancy...

A 54-year-old woman with adenocarcinoma of the lung and lymph node metastasis experienced nystagmus and cerebellar ataxia 2 weeks after initiating nivolumab therapy. An evaluation for several autoimmune-related antibodies and paraneoplastic syndrome yielded negative results. We eventually diagnosed the patient with nivolumab-induced acute cerebellar ataxia, after excluding other potential conditions. Her ataxic gait and nystagmus resolved shortly after intravenous steroid pulse therapy followed by the administration of decreasing doses of oral steroids...

Inflammatory myofibroblastic tumor (IMT) is a peculiar low-grade neoplasm of spindle cell fibroblasts and myofibroblasts in an inflammatory background. The lung is the most common site of involvement. Here, we report a case of paraneoplastic pemphigus (PNP)-associated with an extensive retroperitoneal IMT. The patient had a favourable response following treatment with a low dose of systemic steroid, mycophenolate mofetil, and intravenous immunoglobulin (IVIG). He subsequently underwent surgery for resection of the tumor with nephrectomy and five courses of IVIG were administered after surgery due to a minor relapse...

Digital clubbing is a paraneoplastic phenomenon usually associated with non-small cell lung cancer. We report the development of clubbing in a 49-year old man diagnosed with cutaneous melanoma which had metastasized to the lungs. We also reviewed the literature to understand the association between metastatic melanoma and clubbing. Previous reports of melanoma associated with hypertrophic osteoarthropathy (HOA) are extremely rare; only 7 cases. In all these patients digital clubbing was the main component of the HOA...

In 2013 more than 150,000 Americans died from all types of lung cancer. Small cell lung cancer (SCLC) represents about 13% of all lung cancers and is notoriously associated with paraneoplastic syndromes (PNS). Here we present an interesting case of psychosis associated with one such PNS-- ectopic Cushing syndrome of SCLC. A 56 year old African-American male with no prior psychiatric history who was diagnosed with SCLC two months prior, presented to the ER for treatment of a right arm laceration he sustained while fighting off attackers, with high concern these individuals may have been part of hallucinatory experiences and well-systematized persecutory delusions regarding his wife...

A Stage IV lung adenocarcinoma was diagnosed in the left upper lobe of an 81-year-old man 2.5 years ago. Following another form of chemotherapy, he then received docetaxel as fourth-line therapy. After 21 days of therapy, although his white blood cell count recovered, his platelet count decreased to 20,000/mL and continued to decrease. Subsequently, he was closely monitored without therapy, and eventually, his platelet count returned within the normal range after 112 days. Blood biochemistry and bone marrow paracentesis findings suggested the presence of paraneoplastic syndrome, idiopathic thrombocytopenic purpura, and drug-induced immune thrombocytopenia...

Neuromyelitis optica spectrum disorders (NMOSD) are demyelinating, autoimmune diseases affecting the central nervous system. Typically, recurrent optic neuritis and longitudinal extensive transverse myelitis dominates the clinical picture. In most cases NMOSD are associated with autoantibodies targeting the water channel aquaporin-4 (AQP-4). NMOSD usually present in young adults. Clinical findings suggestive of NMOSD in elderly patients should raise the suspicion of a paraneoplastic etiology. To our knowledge, we report the first case of a 66 year-old female patient with paraneoplastic NMOSD that is associated with squamous cell lung carcinoma...

The majority of small cell carcinoma (SCC) cases originate from the lungs. SCC of the kidneys is rare. Among genitourinary tumors, renal cell carcinoma is the most common type of tumor to be associated with paraneoplastic syndromes. The majority of paraneoplastic syndromes disappear following nephrectomy in renal cell carcinoma cases. The present case involved the assessment of a female patient with SCC of the left kidney. The patient was diagnosed with acute renal failure and underwent a laparoscopic left radical nephrectomy...

Paraneoplastic cerebellar degeneration and Lambert-Eaton myasthenic syndrome (PCD-LEMS) are usually associated with small-cell lung carcinoma (SCLC). PCD-LEMS with extrapulmonary non-SCLC tumors; however, has not been previously reported. A 78-year-old man presented with dysarthria, dysphagia, staggering gait, and lower extremity muscle fatigue. He was diagnosed with PCD-LEMS associated with neuroendocrine carcinoma of the oropharynx, based on the histological findings of the biopsy, the existence of antibodies against P/Q-type voltage-gated calcium channels, and an incremental response of the compound muscle action potentials during repetitive nerve stimulation tests...
