Small Cell Lung Cancer (SCLC), also known as small cell carcinoma or oat cell cancer, is a highly malignant lung cancer of neuroendocrine nature.

Small cell lung cancers produce a number of ectopic hormones, such as ACTH (causing Cushing syndrome) and ADH (causing SIADH). It is also associated with Lambert-Eaton myasthenic syndrome (LEMS), a paraneoplastic syndrome caused by ectopic synthesis of antibodies against voltage-gated calcium channels used by muscle. Other complications can include paraneoplastic encephalitis/myelitis, characterized by the presence of anti-Hu antibodies.
