Primary extrarenal papillary type II renal cell carcinoma presenting as a pelvic mass: a case report and review of the literature.

We report a case of a 57 years old woman with a solitary mass located in the pelvis diagnosed as an extrarenal papillary renal cell carcinoma, in the absence of a primary renal cancer. The diagnosis was based on cytomorphological features and further confirmed by immunochemistry findings following surgical excision. The hypothesis of a tumor developing in a supernumerary or ectopic kidney was excluded, since no normal renal tissue could be identified in the specimen and in the preoperative computed tomography and MRI images.

Giant teratoma of the pancreas expanding to the mediastinum: Rare tumor and literature review.

Pancreatic mature cystic teratomas are very rare with limited cases found in the literature. These lesions raise a diagnostic challenge and complicate the surgical approach not only because of their anatomic position but also because of their ever-growing size. An elusive diagnosis, usually leads to the operative theatre where surgical resection takes place.

Robotic fenestration of massive liver cysts using EndoWrist technology.

Background: We present the short-term outcomes of robotic fenestration of symptomatic liver cysts using the EndoWrist One Vessel Sealer.

Methods: Data from patients who underwent robotic deroofing were collected and analysed retrospectively.

Results: A total of 17 patients were treated.

Predictive significance of preoperative serum VEGF-C and VEGF-D, independently and combined with Ca19-9, for the presence of malignancy and lymph node metastasis in patients with gastric cancer.

Background: Cumulative evidence demonstrate that lymphangiogenic vascular endothelial growth factors (VEGF)-C and -D are over-expressed and associated to lymph node metastasis (LNM) in gastric cancer. The aim of this study is to investigate whether preoperative serum levels of VEGF-C and VEGF-D could be useful tumor markers in patients with operable gastric adenocarcinoma.

Methods: We prospectively examined serum samples from 40 patients and 40 non-cancer controls using enzyme-linked immunosorbent assay (ELISA).

Adrenal ganglioneuromas: incidentalomas with misleading clinical and imaging features.

Background: Ganglioneuromas are benign neoplasms of the neural crest, occurring rarely in the adrenal glands. This study presents our experience regarding diagnostic and therapeutic management of these neoplasms and a review of the relevant literature.

Methods: Among 150 patients with of incidentalomas, we had 7 primary ganglioneuromas.

Pancreatic leak related hemorrhage following pancreaticoduodenectomy. A case series.

Context: Delayed arterial hemorrhage, secondary to pancreaticojejunal leakage, is an infrequent complication (2-4%) of pancreaticoduodenectomy but it carries a high mortality rate with more than half of the patients dying from overwhelming sepsis and/or bleeding. Its ideal management remains unclear.

Case Reports: We hereby present our experience with respect to the presentation and management of this severe post-pancreaticoduodenectomy complication which occurred in 3/149 patients (2.
