Abstract
Small cell lung cancer (SCLC), previously known as oat cell carcinoma, is considered distinct from other lung cancers, which are called non-small cell lung cancers (NSCLC) because of their clinical and biologic characteristics. Small cell lung cancer is a neuroendocrine carcinoma that exhibits aggressive behavior, rapid growth, early spread to distant sites, excuisite sensitivity to chemotherapy and frequent association with distinct paraneoplastic syndromes, including syndrome of inappropriate secretion of antidiuretic hormone (SIADH), ectopic adrenocorticotropic hormone (ACTH) production and many others. Approximately 98% of patients with small cell lung cancer have a smoking history. Here, we report a case of small cell lung cancer in a 70-year-old male presenting to us with bilateral vocal cord palsy and superior vena cava syndrome.

Highlights
Small cell carcinomas are the most malignant tumours of the lung and accounts for 20-25% of all cases
The WHO classification divides small cell carcinoma into three main types- a) Small or oat cell carcinomas characterized by a proliferation of cells with round or oval nuclei and scanty cytoplasm
There are some evidence that this subtype containing some large cells is more resistant to chemotherapy. c) A combined subgroup, which includes rare examples of small cell carcinoma containing areas of squamous carcinoma or adenocarcinoma[1]
Summary
Introduction: Small cell carcinomas are the most malignant tumours of the lung and accounts for 20-25% of all cases. C) A combined subgroup, which includes rare examples of small cell carcinoma containing areas of squamous carcinoma or adenocarcinoma[1]. Small cell carcinomas usually arise in central bronchi.
