Differential expression of NEUROD1, POU2F3, and synaptophysin in combined bladder small cell carcinoma. (A) H&E, low magnification; (B) NEUROD1, low magnification; (C) POU2F3, low magnification; (D) synaptophysin, low magnification; (E) H&E, high magnification; (F) NEUROD1, high magnification; (G) POU2F3, high magnification; (H) synaptophysin, high magnification. H&E, hematoxylin and eosin. These slides illustrate the mutually exclusive expression patterns of NEUROD1 with synaptophysin or POU2F3 alone. H&E, hematoxylin and eosin
