The clinical course of an autoimmune paraneoplastic syndrome parallels the natural history of the primary malignancy. Over the past 25 years adenocarcinoma has become the histological subtype most frequently associated with both sexes and all races combined, replacing squamous cell The most common form of lung cancer [1] Thus, the manifestations of PNS are a result of sites distant from the cancer origin. Sometimes these syndromes may be the first symptoms of lung cancer. Patients can develop . These symptoms aren't directly caused by the spread of cancer but by: Generally, paraneoplastic syndromes are caused by abnormal immune system responses to neoplasms (cancerous tumors). A paraneoplastic syndrome is a syndrome (a set of signs and symptoms) that is the consequence of a tumor in the body (usually a cancerous one), specifically due to the production of chemical signaling molecules (such as hormones or cytokines) by tumor cells or by an immune response against the tumor. Small cell lung carcinoma is the most common cause of SIAD and ectopic Cushing's syndromes. Paraneoplastic syndromes can affect nearly any region of the body and cause many different symptoms.
