Figure 3: Histopathological study of the tumor revealing neuroendocrine carcinoma, compatible with small-cell lung carcinoma. H and E staining (a) showing monotonous tumor cells with high nuclear-cytoplasmic ratio, densely proliferating in an alveolar pattern, as well as mitosis and apoptosis. Immunostaining with neuron-specific enolase (b) and synaptophysin (c) showing strongly positive reaction
