“…This is the case when carcinoid tumors metastasize to the liver or they arise in the bronchus. These tumors release too much of the hormone serotonin and several other chemicals that cause the blood vessels to open (dilate) (2,7).Ectopic production of ACTH and Cushing syndrome have been reported in association with typical and atypical carcinoid tumors. Although less than 1% of pulmonary carcinoid tumors produce Cushing syndrome, it is the second most common neuroendocrine syndrome produced by these tumors.…”

Bronchial Carcinoid Tumor: Case Report

Bronchial carcinoid tumors are an uncommon group of lung tumors. The first report of BCT was by Laennac in 1831. They represent about 1% of all primary lung tumors and about 80% are centrally located, within the lobar and segmental bronchi. 1,2 BCTs were initially classified as benign tumors but now more appropriately classified as malignant tumors. They arise from the kulchitsky cells in the bronchial mucosa, more often in the cartilaginous portion of the tracheobronchial tree, covered by intact epithelium. They are highly vascular and may have a broad based or polypoid attachment. BCTs are capable of secreting biologically active substances. Over 80% of the tumors express somatostatin receptor subtype 2. The cause of BCTs is not proven and there is no strong association with smoking and environmental carcinogens. Familial BCTs have been reported with or without multiple endocrine neoplasia type 1. Leothela et al., 3 attributed BCTs to loss of heterogeneity in multiple chromosomes. The World Health Organization classifies BCTs into 2 groups. Typical BCTs are well differentiated with very low malignant potential, have less than 2 mitotic figures per 10high power field and no evidence of necrosis. Atypical BCT have more than 2-10 mitotic figures per 10 high power field and evidence of necrosis. Typical BCTs are about four times more common than atypical BCTs. We are reporting a case of typical bronchial carcinoid tumor since none has been reported before in the sub-region, to the best of our knowledge.

Bronchial carcinoid tumors: A rare malignant tumor

et al. 2015

Bronchial carcinoid tumors (BCTs) are an uncommon group of lung tumors. They commonly affect the young adults and the middle aged, the same age group affected by other more common chronic lung conditions such as pulmonary tuberculosis. Diagnosis is commonly missed or delayed due to a low index of suspicion. Surgery is the mainstay of treatment with an excellent outcome. There are many reports of this rare group of tumors in the Western and Asian regions. The only report around our sub-region is a post mortem report of an atypical variant. We wish to report a case of the typical variant and increase our index of suspicion. A 25-year-old male presented with a 4 years history of cough and haemoptysis. He was repeatedly treated for bronchial asthma and pulmonary tuberculosis with no improvement of symptoms. Chest X-ray and chest computed tomography scan revealed a left upper lobe tumor. Histology reported a typical variant of BCT which was confirmed by immunohistochemistry. He had a left upper lobectomy and has done excellently well thereafter. A high index of suspicion is needed to reduce the risk of missing or delaying the diagnosis.
