Carcinoid tumors of the lung
Updates to Article Attributes
Carcinoid tumours of the lung are a subgroup of neuroendocrine tumours of the lung, of lower grade than small cell carcinoma of the lung and large cell neuroendocrine carcinoma of the lung.
For a general discussion, please refer to the article on carcinoid tumours.
Pathology
Classification
Carcinoid tumours can be divided into two groups dependent on location:
bronchial carcinoid tumours: central lesions
(commoner ~ 75(most common ~75% 9)peripheral pulmonary carcinoid tumours: peripheral lesions (less common reported range 16-40% 9)
Carcinoid tumours also can be divided into the two histological groups dependent on histology (requires resected specimen rather than biopsy 6) as follows:
-
typical carcinoid tumours of the lung
considered much more common (~90%) 5,9
low grade/well-differentiated 4
-
atypical carcinoid tumours of the lung
less well-differentiated
more aggressive 3,4
Radiographic features
Please refer to location-dependent subtypes above.
