An unusual case of bronchial carcinoid predominantly consisting of large cells.
A 58-year-old woman presented an unusual variant of bronchial carcinoid. A tumor measuring 20 x 25 mm was recognized upon gross examination in the upper lobe of the right lung. Microscopically, the tumor consisted of large polyhedral cells with a pseudoglandular arrangement similar to pheochromocytoma cells. Immunohistochemically, the tumor cells contained serotonin, S-100 protein and neuron-specific enolase. Thus, we consider this neoplasm to be a large cell variant of bronchial carcinoid which, to our knowledge, has not been described in the literature.
