Head and neck synovial sarcoma (HNSS) is a rare tumor with a few case reports or case series being published in the literature. We present the case of a 68-year-old patient admitted to our department for management of a palpable neck mass. After initial investigation and due to major problems of differential diagnosis, there was performed a wide excision of the tumor. Histopathology examination revealed an HNSS.
Background and Objectives: Medullary thyroid carcinoma (MTC) accounts for 1–2% of all thyroid malignancies, and it originates from parafollicular “C” cells. Carcinoembryonic antigen (CEA) is a tumor marker, mainly for gastrointestinal malignancies. There are references in literature where elevated CEA levels may be the first finding in MTC. The aim of this study is to determine the importance of measuring preoperative and postoperative CEA values in patients with MTC and to define the clinical significance of the correlation between CEA and the origin of C cells. Materials and Methods: The existing and relevant literature was reviewed by searching for articles and specific keywords in the scientific databases of PubMedCentraland Google Scholar (till December 2020). Results: CEA has found its place, especially at the preoperative level, in the diagnostic approach of MTC. Preoperative CEA values >30 ng/mL indicate extra-thyroid disease, while CEA values >100 ng/mL are associated with lymph node involvement and distant metastases. The increase in CEA values preoperatively is associated with larger size of primary tumor, presence of lymph nodes, distant metastases and a poorer prognosis. The clinical significance of CEA values for the surgeon is the optimal planning of surgical treatment. In the recent literature, C cells seem to originate from the endoderm of the primitive anterior gut at the ultimobranchial bodies’ level. Conclusions: Although CEA is not a specific biomarker of the disease in MTC, itsmeasurement is useful in assessing the progression of the disease. The embryonic origin of C cells could explain the increased CEA values in MTC.
Background: Meckel’s diverticulum is a common congenital abnormality of the gastrointestinal tract encountered in about 1–3% of the general population. Although most patients remain asymptomatic, a minority will experience serious complications such as acute abdomen, haemorrhage or obstructive ileus. Of all patients presenting with symptoms of obstruction due to Meckel’s diverticulum 7–18% is due to volvulus. Case Report: A 39-year-old male with multiple previous episodes of obstructive ileus presented with an acute abdomen. An exploratory laparotomy was performed in order to reveal the cause of the obstruction. An internal hernia with ileal volvulus and a Meckel’s diverticulum was found, which was later confirmed by histopathological examination. Conclusion: Meckel’s diverticulum is a rare cause of acute abdomen and obstructive ileus which should be considered when the symptoms date back to childhood. The difficulty of preoperative diagnosis dictates the need for exploratory laparoscopy or laparotomy as diagnostic tools.
Patient: Male, 43Final Diagnosis: Splenic aneurysmSymptoms: Ascites • fever • portal hypertensionMedication: —Clinical Procedure: —Specialty: SurgeryObjective:Rare co-existance of disease or pathologyBackground:Splenic aneurysms are rare, asymptomatic, and usually derive from previous surgical interventions. Endovascular repair is the best option, but when A-V shunt is present, open repair might be more suitable.Case Report:A 43-year-old man presented to the Internal Medicine Department of AHEPA University Hospital with symptoms of fever and ascites. He was an ex-medical student with a history of sickle cell anemia, who had undergone urgent splenectomy and cholecystectomy 26 years ago and had a transit ischemic attack at the age of 21 years. Diagnostic imaging control revealed a giant splenic aneurysm 9.8 cm in diameter and 5 cm in length, with a concomitant A-V shunt (due to common ligation of the vessels after splenectomy and long stump presence with concomitant erosion of arterial wall). The patient underwent open surgery and cross-clamping the orifice of the splenic artery, also including the splenic vein, and the vessels were ligated. Post-operatively, the patient remained in the Intensive Care Unit for 48 h and suffered a portal vein thrombosis treated with appropriate anticoagulants. One month later, he had acute hemorrhagic pancreatitis and paralytic ileus and underwent laparotomy performed by general surgeons.Conclusions:Giant splenic aneurysms are rare and are usually caused by previous splenectomy and preservation of a long-vessel stump. Immediate surgical repair is mandatory because of the high risk of rupture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
