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]
- May be multiple.[2]
- Can mimicking metastatic disease.[3]
- Often re-occur - but long term survival good.
- Can be seen in the context of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH).[4][5]
- A common primary lung tumour in children.[6]
- Most common lung tumour in children: metastasis (80-85% of lung tumours in children[7]).
Presentation:[8]
- Cough.
- Hemoptysis.
Treatment:
- Surgical resection.[9]
Gross
- Well-circumscribed, solid.
- Location - central airways (85%), remainder peripheral.[10]
Microscopic
Features:
- Nests of cells.
- Stippled chromatin.
- Scant-to-moderate cytoplasm.
- Nuclei round or ellipsoid.
- No necrosis - important.
- Low mitotic rate.
- Size criterion: >= 5 mm.[11][12]
DDx:
- Pulmonary carcinoid tumourlet.
- Atypical carcinoid lung tumour.
- Lung adenocarcinoma.[13]
- Pulmonary meningothelial-like nodule - usually 1-3 mm, not associated with airway.
Images
Lung carcinoid - low mag. (WC)
Lung carcinoid - high mag. (WC)
Lung carcinoid - very high mag. (WC)
IHC
Proliferation:
- Ki-67 ~2% (range 0-7%).[14]
- Atypical carcinoid is on average 17% (range 10-26%).[14]
Neuroendocrine markers:[15][16]
- Chromogranin A +ve.
- Synaptophysin +ve.
- CD56 +ve.
- Also +ve in pulmonary meningothelial-like nodule.
Others:
- TTF-1 +ve/-ve (11 +ve of 16 cases[17]).
- CK7 +ve/-ve (10 +ve of 16 cases[17]).
- CK20 -ve (0 +ve of 16 cases[17]).

Biopsy
Lung, Left Upper Lobe, Core Biopsy: - Consistent with typical lung carcinoid. Comment: The tumour stains as follow: POSITIVE: CK7, TTF-1 (very weak, focal), CD56, chromogranin A, synaptophysin. NEGATIVE: p63. PROLIFERATION (Ki-67): ~3% of tumour cells.
Excision
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.
