Abstract
INTRODUCTION Gangliocytic paraganglioma is an extremely rare tumor that is composed of epithelioid, ganglion, and spindle cells. It has a predilection site in the duodenum, especially the periampullary region. The clinical course is usually benign, but a few cases of metastasis to lymph nodes or distant sites have been noted. Several case reports or small series reviews of gangliocytic paraganglioma have been published, but so far, cecal gangliocytic paraganglioma has not been described. CASE DESCRIPTION A 61-year-old man underwent an abdominal Computed Tomography (CT) scan for known GB stones, which revealed an incidental cecal mass. The patient underwent wedge resection of the cecum for diagnostic and therapeutic purposes. Histopathological examination of the cecal mass identified a gangliocytic paraganglioma. There was no evidence of metastasis in the dissected regional lymph nodes. No additional treatment, such as adjuvant chemotherapy or radiotherapy, was administered, and the patient underwent regular follow-up without any complications. CONCLUSION The most common radiologic finding in gangliocytic paraganglioma is a circumscribed, enhancing subepithelial mass. Herein, we report an uncommon case of cecal-origin gangliocytic paraganglioma. With knowledge of the radiologic and histologic characteristics of gangliocytic paraganglioma, appropriate management can be provided without unnecessary radical resection.

Abstract
BACKGROUND Gangliocytic paraganglioma (GP) is rare and difficult to be differentiated from other periampullary neoplasms. The clinical characteristics and optimal treatment of periampullary GPs have not been clarified. METHODS The data pool for the analysis comprised of cases of periampullary GP encountered in our institution and sporadic cases reported in the English literature. RESULTS A total of 117 cases with periampullary GP were studied, including 2 from our institute, and among them, duodenal GP was the most common (53.0%). GP size ranged from 0.7 to 19.0 cm, with a median of 2.2 cm. The most common presenting symptom for overall periampullary GPs was epigastric pain in 49.5% cases, followed by gastrointestinal bleeding in 35.4% cases. Most (84.1%) of the periampullary GPs were benign, whereas 15.9% were malignant. Metastasis was noted in 26.3% of periampullary GPs, with 14.5% showing lymph node metastasis and 1.8% showing liver metastasis. Of the periampullary GP cases included, 30.1% were treated with pancreaticoduodenectomy, 40.6% with local excision, and 17.7% with endoscopic resection. CONCLUSIONS Periampullary GP should be considered as a tumor with malignant potential. Endoscopic resection is the treatment of choice for most of the duodenal GPs, whereas pancreaticoduodenectomy is recommended for GPs with possible malignancy, such as large size, with submucosal invasion, or pancreatic GP.

Abstract
Duodenal gangliocytic paragangliomas are extremely rare. A 79-year-old woman underwent gastrointestinal endoscopy for screening prior to resection of gallbladder carcinoma. Gastrointestinal endoscopy revealed a 5-mm submucosal tumor in the second portion of the duodenum. Contrast-enhanced computed tomography revealed no tumor or metastasis. Endoscopic ultrasonography revealed low echo pattern of the tumor. Histopathological examination of the biopsy specimen revealed proliferation of three types of cells (epithelioid cells, spindle cells, and ganglion cells). Immunohistochemical examination revealed that the tumor was positive for S-100 and synaptophysin. The preoperative diagnosis was gangliocytic paraganglioma. The tumor was completely resected by endoscopic mucosal resection (EMR). In conclusion, an early stage of gangliocytic paraganglioma of the duodenum could be resected using EMR.

Abstract
The purpose of this two-part article is to review the cross-sectional anatomy of the ampulla and periampullary region, to propose novel and optimized MDCT and MRI techniques that allow accurate evaluation of the ampulla of Vater, and to summarize the cross-sectional imaging features of benign and malignant ampullary conditions. In this first part, we will review the normal anatomy of the ampullary region, provide suggestions on how to optimize evaluation of the ampullary region by MDCT and MRI, and review the imaging features of select epithelial neoplasms of the ampulla. Familiarity with the normal ampullary anatomy and the pathologic conditions involving the ampulla, as well as the use of optimized MDCT and MRI techniques, may improve the diagnostic accuracy of radiologists facing ampullary abnormalities.

Abstract
Gangliocytic paraganglioma (GP) is a rare, benign tumor which is usually found in the duodenum. We here report four recent cases of GP, with successful endoscopic resection in three cases, including a lesion on the ampulla of Vater. In all cases, each lesion had a stalk that facilitated removal using an endoscopic approach. Endoscopic mucosal resection is a feasible and safe treatment if the location, depth, and lymph node status are all favorable and is also helpful for definite diagnosis of unknown duodenal mass. To avoid morbidity resulting from open surgical resection, careful inspection for the peduncle of the GP will help determine the feasibility of endoscopic resection.

Abstract
We describe a case of duodenal gangliocytic paraganglioma showing lymph node metastasis. A 61-year-old Japanese man underwent pylorus preserving pancreaticoduodenectomy to remove a tumor at the papilla of Vater. The section of the tumor extending from the mucosa to submucosa of the duodenum was sharply demarcated, solid, and white-yellowish. Neither necrosis nor hemorrhage was present. Histological examination confirmed the immunohistochemical identification of three components comprising epithelioid cells, spindle-shaped cells, and ganglion-like cells. Epithelioid cells showed positive reactivity for synaptophysin, somatostatin, and CD56. In contrast, spindle-shaped cells showed positive reactivity for S-100 protein, but not for synaptophysin, somatostatin or CD56. Furthermore, we found lymph node metastasis despite lack of bcl-2 and p53 expression. In addition to the rarity of the tumor, we are describing here the present case suggests the malignant potency of the tumor despite lack of acceptable prognostic indicators for neuroendocrine tumor.

Abstract
Gangliocytic paraganglioma (GPG) is a rare tumor, occurring almost exclusively in the duodenum. In the present case, a submucosal tumor 2.5 x 2 x 1.5 cm in size was located on the anal side of the papilla of Vater, with clear margins and without capsule on cut-surface examination. Tumor cells included three types of cells: ganglion-like cells (GCs), endocrine cells (ECs), and Schwann cells (SCs). The GCs were large with eccentric nuclei with large nucleoli and clear abundant cytoplasm. ECs were detected in small nests, surrounded by bundles of SCs. Immunohistochemically, GCs were positive for synaptophysin, neuron-specific enolase (NSE), and CD56. ECs were positive for chromogranin A, NSE, somatostatin, pancreatic polypeptide, and CD56, and were associated with S100 protein-positive SCs. On fine structural examination, ECs contained numerous membrane-bounded secretory granules, 250-450 nm in diameter, in their cytoplasm, surrounded by a branched, complex basal lamina. SCs possessed basal lamina along their long interlacing cytoplasmic processes. The histogenesis of GPG most likely involves proliferation and differentiation of pluripotent stem cells in the duodenal crypts in the duodenum as a true tumor, although it is also possible that the retroperitoneal components of both GCs and SCs proliferate, together with ECs, from ventral primordial tissue of the pancreas in the duodenum. The immunohistochemical and ultrastructural findings of a case of GPG are reported, focusing on three major cellular components: GCs, ECs, and SCs.
