Small cell lung cancer mostly arises centrally in the large bronchi. The literature search revealed very limited cases of small cell lung cancer arising at the upper part of the pulmonary sulcus near the thoracic inlet as superior sulcus tumor and also manifesting with typical Pancoast syndrome. We report a case of a 71 years old male patient, presenting with features of Pancoast syndrome including Horner's syndrome with completed three cycles of chemotherapy resulting in partial response which concludes that small cell lung carcinoma has to be considered despite the clinical findings like pancoast syndrome.
