Case Discussion

Carcinoids are tumors that originate from cells of the diffuse neuroendocrine system (APUD cells). Most carcinoids appear as a vegetative lesion with endoluminal growth in the large bronchi, the onset symptomatology is often related to bronchial obstruction and may produce atelectasis or obstructive pneumonia.
