Large cell carcinoma of the lung presenting as diffuse pulmonary infiltrates with haemoptysis

We report a case of large cell carcinoma identified during differential diagnosis of diffuse alveolar haemorrhage in a patient with haemoptysis. AbstractDue to rapid advances in our understanding of the molecular pathogenesis of non ‐small cell lung cancer (NSCLC), the 2015 World Health Organization (WHO) classification has defined large cell carcinoma (LCC) as a subtype that is lacking glandular or squamous cells, and any neuroendocrine differentiation. Accordingly, LCC is one of the rarest subtypes of NSCLC. LCC usually pre sents as a large peripheral tumour with prominent necrosis and its specific characteristics are not well known. Here, we report a case of LCC identified during differential diagnosis of diffuse alveolar haemorrhage in a patient with haemoptysis.
