Large cell carcinoma of the lung
Large cell carcinoma of the lung is one of the histological types of non-small cell carcinomas of the lung.
It is thought to account for approximately 10% of bronchogenic carcinoma 1.
Patient presents with dyspnea, chronic cough and haemoptysis.
Microscopically large cell carcinoma is characterised by large nuclei/nucleoli with moderate amount of cytoplasm, hence the name large cell carcinoma. This undifferentiated tumour lacks distinctive features of small cell carcinoma, glandular or squamous differentiation. A histological subtype is large cell neuroendocrine carcinoma 3.
On immunophenotyping characteristic features include 2:
- loss of staining with CK5/6
- CK14 positive in most squamous cell carcinoma (SCC)
- lack of MOC 31 positive in most adenocarcinomas
- positive immunoreactivity to EGFR, PDGFR-alpha and c-kit.
Large cell carcinoma of the lung typically presents as a large peripheral mass of solid attenuation and irregular margin. Focal necrosis can be present. Other characteristics include rapid growth and early metastasis.
Treatment and prognosis
The histologic subtype of large cell neuroendocrine tumour has a more aggressive pattern and is associated with poorer prognosis.
