Primary bronchial carcinoid: A rare differential diagnosis of pulmonary koch in young adult patient
Bronchial carcinoids are uncommon, slow growing, low-grade malignant neoplasms comprising 1-2% of all primary lung cancers. They are thought to arise from neuroendocrine/Kulchitsky′s cells of bronchial epithelium. Histological features range from low-grade typical to more aggressive atypical carcino...

| Summary: | Bronchial carcinoids are uncommon, slow growing, low-grade malignant neoplasms comprising 1-2% of all primary lung cancers. They are thought to arise from neuroendocrine/Kulchitsky′s cells of bronchial epithelium. Histological features range from low-grade typical to more aggressive atypical carcinoids. Clinically they may be asymptomatic, present with nonresolving recurrent pneumonitis, hemoptysis, or with paraneoplastic syndromes. Central bronchial carcinoids are more common than the peripheral type and are seen as endobronchial nodule or hilar/perihilar mass closely related to the adjacent bronchus. Chest X-ray may not show the central lesion due to its smaller size as is in our case. Contrast-enhanced computerized tomography (CECT) remains a highly sensitive examination which shows an intensely enhancing small rounded endobronchial nodule. We present a case of recurrent pneumonitis and hemoptysis in a young patient who showed features of typical central bronchial carcinoid in CECT and later confirmed with histopathological examination (HPE). |
