We describe the clinical, imaging and cytopathological features of solid pseudopapillary tumor of the pancreas (SPTP) diagnosed by endoscopic ultrasound-guided (EUS-guided) fine-needle aspiration (FNA). A 17-year-old woman was admitted to our hospital with complaints of an unexplained episodic abdominal pain for 2 mo and a short history of hypertension in the endocrinology clinic. Clinical laboratory examinations revealed polycystic ovary syndrome, splenomegaly and low serum amylase and carcinoembryonic antigen (CEA) levels. Computed tomography (CT) analysis revealed a mass of the pancreatic tail with solid and cystic consistency. EUS confirmed the mass, both in body and tail of the pancreas, with distinct borders, which caused dilation of the peripheral part of the pancreatic duct (major diameter 3.7 mm). The patient underwent EUS-FNA. EUS-FNA cytology specimens consisted of single cells and aggregates of uniform malignant cells, forming microadenoid structures, branching, papillary clusters with delicate fibrovascular cores and nuclear overlapping. Naked capillaries were also seen. The nuclei of malignant cells were round or oval, eccentric with fine granular chromatin, small nucleoli and nuclear grooves in some of them. The malignant cells were periodic acid Schiff (PAS)-Alcian blue (+) and immunocytochemically they were vimentin (+), CA 19.9 (+), synaptophysin (+), chromogranin (-), neuro-specific enolase (-), a1-antitrypsin and a1-antichymotrypsin focal positive. Cytologic findings were strongly suggestive of SPTP. Biopsy confirmed the above cytologic diagnosis. EUS-guided FNA diagnosis of SPTP is accurate. EUS findings, cytomorphologic features and immunostains of cell block help distinguish SPTP from pancreatic endocrine tumors, acinar cell carcinoma and papillary mucinous carcinoma.

A 14-year-old male mixed breed dog was presented for abdominal distension and abdominal pain. Radiographical examination identified a large space-occupying mass in the abdomen. Necropsy examination revealed the presence of a 12cm hepatic mass that occupied almost half of the abdominal cavity. Microscopically, this mass consisted of spindle-shaped neoplastic cells that were arranged in short streams and interlacing bundles. Immunohistochemically, the neoplastic cells expressed vimentin, S-100, protein gene product 9.5 and neuron specific enolase, but were negative for cytokeratin, smooth muscle actin, melan A and von Willebrand Factor. These findings indicated that the hepatic mass was a primary hepatic peripheral nerve sheath tumour. To our knowledge, this is the first documentation of a primary hepatic malignant peripheral nerve sheath tumour in a dog.

Large cell neuroendocrine carcinoma (LCNEC) of the uterine cervix is very rare and aggressive. The prognosis is very poor despite multimodal treatment. We report a virgin woman with FIGO stage 4b LCNEC of uterine cervix coexisting with squamous cell carcinoma. An early thirties virgin woman presented with 2-month history of abdominal pain. A chest X-ray showed multiple lung metastatic tumors. A vaginal smear showed malignant cells, and a biopsy specimen had features of LCNEC. The tumor showed trabecular patterns. Tumor cells possessed a moderate amount of cytoplasm, prominent nucleoli, and large nuclei. The tumor cells are stained positive for synaptophysin, chromogranin A, and neuron specific enolase (NSE). The invasive tumor cells in connection with cervical squamous epithelium were focally positive for 34bE12. We made a diagnosis of composite LCNEC and nonkeratinizing squamous cell carcinoma. High-risk HPV test was negative with hybridized captured method 2.

Gangliocytic paraganglioma is a rare neuroendocrine tumor predominantly arising in the second part of the duodenum with rare local recurrence or metastasis to regional lymph nodes. A 92-year-old female presented with obstructive jaundice. On exam she had pale conjunctiva and icteric sclera. Abdominal examination revealed tenderness in the upper abdomen. Laboratory data was consistent with obstructive jaundice. Computed tomography of the abdomen revealed a dilated gall bladder and a common bile duct (CBD) with no evidence of liver lesions or pancreatic head mass. Endoscopic ultrasonography revealed a 1 cm isoechoic submucosal nodule at the periampullary area, dilated CBD (9 mm), a prominent pancreatic duct (4.1 mm) and a hydropic gall bladder with no stones. Endoscopic retrograde cholangiopancreaticography was performed to relieve obstruction and showed a 1 cm periampullary mass which underwent an en-bloc snare resection. Histopathology analyses with immunohistochemical stains were positive for cytokeratin, synaptophysin, S-100 protein, neuron specific enolase and negative for actin and desmin consistent with periampullary gangliocytic paraganglioma. Periampullary gangliocytic paraganglioma is a rare benign tumor of the small bowel. Common presentation includes abdominal pain and obstructive jaundice which should be included in differential diagnosis of obstructive jaundice. Endoscopic resection is a curative therapy in the absence of local invasion or distant metastasis.

Gangliocytic paraganglioma (GP) is a rare tumor of uncertain origin most often located in the second portion of the duodenum. It is composed of three cellular components: Epithelioid endocrine cells, spindle-like/sustentacular cells, and ganglion-like cells. While this tumor most often behaves in a benign manner, cases with metastasis are reported. We describe the case of a 62-year-old male with a periampullary GP with metastases to two regional lymph nodes who was successfully treated with pancreaticoduodenectomy. Using PubMed, EMBASE, EBSCOhost MEDLINE and CINAHL, and Google Scholar, we searched the literature for cases of GP with regional lymph node metastasis and evaluated the varying presentations, diagnostic workup, and disease management of identified cases. Thirty-one cases of GP with metastasis were compiled (30 with at least lymph node metastases and one with only distant metastasis to bone), with age at diagnosis ranging from 16 to 74 years. Ratio of males to females was 19:12. The most common presenting symptoms were abdominal pain (55%) and gastrointestinal bleeding or sequelae (42%). Twenty-five patients underwent pancreaticoduodenectomy. Five patients were treated with local resection alone. One patient died secondary to metastatic disease, and one died secondary to perioperative decompensation. The remainder did well, with no evidence of disease at follow-up from the most recent procedure (except two in which residual disease was deliberately left behind). Of the 26 cases with sufficient histological description, 16 described a primary tumor that infiltrated deep to the submucosa, and 3 described lymphovascular invasion. Of the specific immunohistochemistry staining patterns studied, synaptophysin (SYN) stained all epithelioid endocrine cells (18/18). Neuron specific enolase (NSE) and SYN stained most ganglion-like cells (7/8 and 13/18 respectively), and S-100 stained all spindle-like/sustentacular cells (21/21). Our literature review of published cases of GP with lymph node metastasis underscores the excellent prognosis of GP regardless of specific treatment modality. We question the necessity of aggressive surgical intervention in select patients, and argue that local resection of the mass and metastasis may be adequate. We also emphasize the importance of pre-surgical assessment with imaging studies, as well as post-surgical follow-up surveillance for disease recurrence.
