Abstract

*Introduction* Lung carcinoid tumor comprises 1-2% of all lung cancer however atypical lung carcinoid carry high risk of malignant transformation. Carcinoids are strongly and diffusely positive for neuroendocrine markers and commonly used markers include synaptophysin, chromogranin A, and CD56/NCAM. *Case Report* A 43 year old lady presented initially to surgical team with history of chronic diarrhoea for more than 20 times for a year. Further history suggests that she had flushing of the face. She had significant loss of weight nearly 18 kg. OGDS done with normal finding and colonoscope revealed multiple none bleeding cecal diverticulum. Clinically patient had hepatomegaly thus decided by surgical team for CT liver and subsequently CT Thorax (based on CT liver finding). CT liver revealed multiple liver masses and incidental finding of right lung mass. CECT thorax which was ordered subsequently captured a minimally enhancing irregular hypodense mass at medial segment of right lower lobe measuring 4.1 cm x 3.2 cm x 2.2 cm with evident of bone metastasis. Patient was referred to respiratory team for further management. Bronchoscopy was done and noted narrowed opening of right lower lobe medial segment and unable to pass scope further but can see mass at tertiary carina. There is no endobronchial lesion and transbronchial lung biopsy (TBLB) under fluoroscopy was done. Histopathology report is consistent with atypical carcinoid. The neoplastic cells are strong and diffusely positive for Chromagranin A, Synaptophysin, CD56 and focally positive for CK7. A full diagnosis of malignant lung carcinoid with liver and bone metastasis was made and patient was referred to oncology team for Dotatate PET scan, initiation of sandostatin and further management. *Conclusion* Physician should always have high suspicious and include a differential diagnosis of carcinoid syndrome in a patient with chronic diarrhea and flushing despite of its rarity.
