Fig. 6From: Hypothalamic hypopituitarism secondary to suprasellar metastases from small cell lung cancer: a case report and review of the literaturePathological results obtained from the bronchoscopic biopsy indicating a small cell lung cancer. Hematoxylin and eosin stain shows sheets, rosettes, or peripheral palisading of small-sized round cells with minimal cytoplasm. Densely packed small tumor cells were reactive for cytokeratin (AE1/AE3), CD56, chromogranin, and synaptophysin antibodies immunohistochemically. a Hematoxylin and eosin stain, × 100 magnification. b Hematoxylin and eosin stain, × 1000 magnification. c AE1/AE3 immunostain, × 400 magnification. d CD56 immunostain, × 400 magnification. e Chromogranin immunostain, × 400 magnification. f Synaptophysin immunostain, × 400 magnificationBack to article page
