Plain-English summary
A 10-year-old cat was brought in because it had been coughing, having trouble breathing, and not eating well. The veterinarian found a yellowish mass in the cat's trachea that was blocking part of the airway. Unfortunately, after further tests and a post-mortem examination, it was determined that the cat had a type of cancer called neuroendocrine carcinoma. Sadly, the cat did not survive due to this serious condition.

Abstract
A tracheobronchial neuroendocrine carcinoma in a 10-year-old cat with a history of coughing, dyspnoea and anorexia is described. Endoscopic examination revealed a yellowish mass protruding into the trachea and partly obstructing the right bronchial lumen. Histological examination of biopsy samples revealed a hypercellular tumour consisting of sheets or ribbons of small hyperchromatic cells, with oval to spindle-shaped nuclei and minimal cytoplasm; nucleoli and mitotic activity were absent. The findings were confirmed on post-mortem examination. The small neoplastic cells were immunolabelled to varying degrees by antibodies against neuron-specific enolase, S-100 protein, synaptophysin and vimentin. Ultrastructural studies revealed scattered neurosecretory granules and scanty cellular junctional complexes, including desmosomes and tonofilaments, in neoplastic cells.
