Small cell carcinoma is a type of highly malignant[1] carcinoma usually associated with the lung, though it can be associated with other topographies, such as in cervical cancer.

Types
Paraneoplastic Syndromes: Small cell carcinomas produce ACTH and ADH
Lung
When associated with the lung, it is sometimes called "oat cell carcinoma" due to the flat cell shape and scanty cytoplasm.
It is thought to originate from neuroendocrine cells (APUD cells) in the bronchus called Feyrter cells (named for Friedrich Feyrter),[2] and often leads to ectopic production of hormones ADH and ACTH.
It is more metastatic than non-small cell lung carcinoma[3] (and hence staged differently) and is sometimes seen in combination with squamous cell carcinomas.
Smoking is a significant etiological factor.
Symptoms and signs are as for other lung cancers. In addition, because of their neuroendocrine cell origin, small cell carcinomas will often secrete substances that result in paraneoplastic syndromes such as Lambert-Eaton myasthenic syndrome.
Prostate
In the prostate, small cell carcinoma is a rare form of cancer.[4] Due to the fact that there is little variation in prostate specific antigen levels, this form of cancer is normally diagnosed at an advanced stage.
It can metastasize to the brain.[5]
