Case report: Primary pleural giant extraskeletal Ewing sarcoma in a child.

Primary extraskeletal Ewing sarcoma (EES) is a rare small round cell malignancy that accounts for less than 1% of all sarcomas. It is found most commonly in the trunk and lower limbs and very rarely in the pleura and can be easily misdiagnosed in clinical practice. This study presents the case of an 11-year-old boy who presented to our hospital with no apparent cause of left shoulder pain for 6 months.

Three-in-one incidence of hepatocellular carcinoma, cholangiocellular carcinoma, and neuroendocrine carcinoma: A case report.

Background: Primary hepatic neuroendocrine carcinoma (NEC) is rare, and a combination with hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) is extremely rare. To date, only four combination cases have been reported. The present paper describes the fifth patient.

Primary signet-ring cell carcinoma of the extrahepatic bile duct: A case report.

Background: Signet ring cell carcinoma (SRCC) is a specific type of mucinous secretory adenocarcinoma, which contains abundant mucus in the cytoplasm and pushes the nucleus to one side of the cell membrane, forming a round or oval, and the nuclear deviations give the cells a signet ring-like appearance. SRCC often originates in the gastrointestinal tract, especially in the stomach. However, primary SRCC of the extrahepatic bile duct is extremely rare.

Removal of "ruptured" pulmonary artery infusion port catheter by pigtail catheter combined with gooseneck trap: A case report.

Background: Implanted intravenous infusion port (IVAP) is indicated for patients undergoing chemotherapy, total parenteral nutrition and long-term antibiotic treatment. Among their complications, the rupture and migration of the catheter of an IVAP internal jugular vein represents a very rare but potentially severe condition.

Case Summary: A 43-year-old woman was identified with a spontaneous fracture and migration of catheter of an IVAP right internal jugular vein after adjuvant chemotherapy for left breast cancer.
