A case of bronchial/lung carcinoid cytological, histological and immunohistochemical corroboration

Lung carcinoids tumors are uncommon tumors that start in the lung. They tend to grow slower than other types of lung cancers. Carcinoids tumors start from cells of the diffuse neuroendocrine system. It is widely recognized that cytology is superior to small biopsy in diagnosing small cell lung carcinoma since the crush artefacts limiting small biopsy interpretation is minimized in cytology. Similarly, carcinoids can be accurately diagnosed in cytology and small biopsy specimen. A correct preoperative cytological diagnosis helps in planning early and optimal surgery. We received the fine-needle aspiration cytology sample of bronchial mass of 46-year-old patient presenting with cough and hemoptysis for 2 months. Diagnosis of carcinoid tumor was given on cytology that was confirmed on histopathology and immunohistochemistry.
