Typical pulmonary carcinoid tumour is a subtype of pulmonary carcinoid tumour. It is an uncommon low-grade malignant lung mass that is most often in the central airways of the lung.[1]
Signs and symptoms
[edit]Lung carcinoids typically present with a cough or hemoptysis.[2] Findings may closely mimic malignant tumours of the lung, i.e. lung cancer.[citation needed]
Diagnosis

The definitive diagnosis is rendered by a microscopic examination, after excision. Typical carcinoids have cells with stippled chromatin and a moderate quantity of cytoplasm. They typically have few mitoses and lack necrosis. By definition, they are greater than 4 mm in largest dimension; smaller lesions are referred to as pulmonary carcinoid tumourlets.[citation needed]
The differential diagnosis of typical pulmonary carcinoid tumour includes: atypical pulmonary carcinoid tumour, pulmonary carcinoid tumourlet and lung adenocarcinoma.[citation needed]
