Lung Paraneoplastic Syndromes Rash
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Is there research into any genetic, autoimmune or other condition that links nerve sheath disorders (tarlov cysts, nerve sheath tumor) with autoimmune hypophysitis targeting acth cells? Ctla-4 gene?
Neurologist or oncologist for paraneoplastic neurological syndrome?Maybe sclc?-smoked 10yr. Now: dysesthesias, fatigue, cold/heat intolerant, no hunger.
A friend had chronic demyelinating polyneuropathy (cidp), then got chronic lymphocytic leukemia 2 years later. Is cidp paraneoplastic syndrome sometimes?
Not likely: Chronic inflammatory demyelinating polyradiculopathy (cidp) is almost always an autoimmune condition incited by some antecedent infection--c. Jejuni, ebv, cmv, or another infection. Antibodies produced against the virus/ bacteria/ pathogen cross-react with the myelin sheath on the nerve roots, first causing guillain-barre (aidp), then later cidp. It's exceedingly rare that cancer could cause this. ...Read moreSee 2 more doctor answers

Severe HPV (plantars), sarcoidosis w/ atypical lung nodules 8mm with suv of 10.9 what are chances of cancer? No lung bx done other site pos for sarc
Hard to say: Do you have significant risk for lung cancer? Are you a smoker? If yes, you need to stop smoking . The lung nodule is likely sarcoidosis of the lung although if you are also a heavy smoker, lung cancer is possible. I will suggest you to have a follow up ct scan to ensure stability if it is rapidly growing, while your sarcoidosis is quite without symptom perhaps biopsy can be considered then. ...Read moreSee 1 more doctor answer
What kind of test can diagnose Peripheral neuropathy- Paraneoplastic syndromes of the nervous system?
Physical & labs: If physical exam suggests peripheral neuropathy, the workup will include assays for a few of the paraneoplastic autoantibodies known to cause it, and a diligent search for an underlying cancer should be undertaken. This is a difficult workup for physician and patient alike, and I wish you luck. Stay proactive. ...Read more
Many genes: The previous answer is right with several genes associated with lupus, but no one knows how those genes cause disease. I think it's important to remember that there is likely many ways to develop lupus symptoms, and this will vary between people. So some of these known genes will be important for some, and not important for others. As we sequence more patients, we'll have more answers. ...Read moreSee 1 more doctor answer
Multilobulated pulmonary mass w/calcifications in left upper lobe. Neoplastic disease vs inflammatory/infectious process. rule out metastatic disease ?
In general...: IN GENERAL, a multilobulated mass is more likely malignant, one with calcifications is less likely. As in much else, size matters, with bigger being more worrisome. If you're smoker, more likely malignant, if from place of endemic TB or histoplasmosis, risk of chronic infection rises. You'll need to be evaluated by a pulmonologist, who will very likely recommend biopsy. ...Read more

Can small cell lung cancer cause malabsorption through zolinger Ellison syndrome. Would this be a presenting sign of sclc before it shows on ct scan?
Uncommon: Most Zollinger-Ellison / gastrinoma are from islet cell tumors of the foregut. Oat cell carcinoma can produce other paraneoplastic syndromes, famously the anti-nerve cell ones, before being visible on chest ray, but it announces itself fast enough. And what are you going to without a localized tumor? Take out both lungs? Look for some other cause for any suggestive symptoms. Good question Gill. ...Read more

What is the best indicator of cancer: "tumor markers" or "paraneoplastic autoantibodies"? I have signs of cancer and neurological autoimmunity.
Neither: There are only a handful of very rare circumstances where a "tumor marker" blood test can prove that someone has a cancer. This is because many tumor markers can be elevated by other causes. Paraneoplastic autoantibodies do not diagnose cancer but are called that when a patient with a known cancer has autoantibodies without another known cause. ...Read moreSee 1 more doctor answer
