Typical carcinoid lung tumour, also lung carcinoid and carcinoid tumour of the lung, is a benign lung tumour, that is excised to exclude malignancy.
General
- Approximately 80% of lung carcinoids.[1]
Presentation:[2]
- Cough.
- Hemoptysis.
Gross
- Well-circumscribed, solid.
- Location - central airways (85%), remainder peripheral.[3]
Microscopic
Features:
- Nests of cells.
- Stippled chromatin.
- Moderate cytoplasm.
- No necrosis.
- Low mitotic rate.
- Size criterion: >= 5 mm.[4][5]
DDx:
Images
Lung carcinoid - low mag. (WC)
Lung carcinoid - high mag. (WC)
Lung carcinoid - very high mag. (WC)
IHC
- Ki-67 ~2%.[7]
Note:
- Atypical carcinoid is considerably higher ~17%.[7]
Sign out
A. Lymph Node, Station 2L, Lymphadenectomy: - Lymph node, NEGATIVE for malignancy. B. Lymph Node, Station 4L, Lymphadenectomy: - Lymph node, NEGATIVE for malignancy. C. Lymph Node, Station 11L, Lymphadenectomy: - Lymph node, NEGATIVE for malignancy. D. Lung, Left Upper Lobe, Lobectomy: - Typical carcinoid tumour (12 mm maximal dimension). - Carcinoid tumourlet (2 mm maximal dimension). - Margins clear of tumour. - Please see tumour summary.
