Gastrointestinal stromal tumor in the fourth portion of the duodenum does not express the CD117: A case report.

Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the digestive tract.

Presentation Of Case: 54-year-old woman with a history of phyllodes tumor of the left breast he patient was admitted to our hospital for management of retroperitoneal soft tissue tumor, attached to the fourth portion of the duodenum, opposite the head of the pancreas. The patient underwent a large excision of the tumor, the duodenojejunal flexure, and the third and fourth portions of the duodenum along with the head of the pancreas.

A rare association of Vagus Nerve Schwannoma and Pheochromocytoma: A case report.

Vagus nerve schwannoma is a very rare benign nerve tumor. Pheochromocytoma is a rare, mostly benign tumor of the adrenal medulla with a large clinical spectrum. Their association is uncommon.

Intraductal papillary mucinous neoplasm of the pancreas presenting as a giant abdominal mass: A case report.

Introduction: Intraductal papillary mucinous neoplasms (IPMNs) constitute a group of rare conditions with a potential for malignant degeneration. The appearance of symptoms should suggest degeneration. This case demonstrates an unusual case of a patient presenting an intestinal type IPMN that was revealed by a large abdominal mass.

Extra gastrointestinal stromal tumor EGIST in the recto-vesical pouch: A case report and literature review.

Introduction: Extra-gastrointestinal stromal tumors (EGISTs) are rare mesenchymal tumors located outside the gastrointestinal tract, and exhibit the same phenotypic and morphological profile of gastrointestinal stromal tumors (GISTs).

Case Report: We report the case of a 20-year-old male patient consulted for chronic discomfort in the hypogastric region. Abdominal ultrasound and abdomino-pelvic CT scan identified a retro-vesical mass measuring 16 × 9 cm.

Fishbone-Induced Appendicitis: A Case Report.

Fishbone ingestion is quite common. Most of the time, patients are asymptomatic and the fish bone exits the gastrointestinal tract spontaneously. However, in some rare cases, it can drop in the appendix and induce appendicitis or even appendicitis with perforation.

Retroperitoneal Schwannoma: Two Rare Case Reports.

Schwannomas are neuroectodermal tumors that rarely occur in the retroperitoneal space. We report two cases of patients who presented with abdominal pain. Radiological findings revealed a retroperitoneal mass in both cases.

Parathyroid Cyst: A Case Report of an Uncommon Diagnosis of a Cervical Mass.

Parathyroid cysts (PCs) are uncommon entities in clinical practice. The lack of pathognomonic clinical presentation and radiological features of PCs makes preoperative diagnosis unlikely, therefore, most cases are diagnosed intraoperatively or postoperatively at the pathological analysis of the surgical specimen. Treatment of nonfunctional PCs remains controversial and includes fine-needle aspiration, injection of sclerosant, or surgical excision.

Myxoid Liposarcoma: A Case Report of a Rare Location in the Abdominal Wall.

Liposarcomas are considered to be the most common soft tissue sarcomas and have five histological subtypes. The myxoid subtype often occurs in the lower limbs and the retroperitoneum; however, the abdominal wall location is extremely rare. The clinical presentation and radiological findings are non-specific.
