Hepatic paraganglioma and multifocal gastrointestinal stromal tumor in a female: Incomplete Carney triad

Figure 2 The patient underwent total gastrectomy, regional lymphadenectomy, and partial hepatectomy of segment VII. A: Macroscopically, gastric tumors were located in the submucosal layer, were round to oval and, relatively well demarcated, and exhibited multiple nodules (n = 8); B: Gastric tumor demonstrated cellular epithelioid gastrointestinal stromal tumors with discohesive pattern of growth (HE, × 40) and mild nuclear atypia (hematoxylin and eosin, × 200) (lower right), exhibiting diffuse cytoplasmic membranous immunoreactivity for CD117 (immunohistochemical stain, × 200) (upper right); C: Hepatic partial resection revealed an oval, well circimscribed, orange yellow, soft, solid tumor, 12 mm × 7 mm (left) and microscopically, synaptophysin-positive, hepatic tumor cells were arranged in nests (so called‘zellballen’) (right), surrounded by S100 protein-positive, sustentacular cells (immunohistochemical stain, × 400).
