Head and neck paraganglioma is a rare and predominantly asymptomatic tumor. In the present study, an extremely rare case of asymptomatic paraganglioma located between the left common carotid artery and the left thyroid is described. The clinical presentation, cytomorphology and the immunohistochemical characteristics for the diagnosis of head and neck paraganglioma are described. To the best of our knowledge, only two cases of paraganglioma located between the left common carotid artery and the left thyroid have previously been reported.

Objectives: Pheochromocytomas and paragangliomas (PPGLs) are manifestations of von Hippel-Lindau (VHL) disease. This study aims to describe the clinical features of PPGLs in VHL patients and the distinctions between VHL disease-related PPGLs and sporadic PPGLs.
Design, Patients And Measurements: The study included all patients with VHL disease and PPGLs treated in a single centre from 2007 to 2023.

Introduction And Importance: Cervical paragangliomas of the vagus nerve are tumors, of wich the nature and location make them extremely rare, representing only 0.012 % of cervical tumors.
Case Presentation: This article reports the case of a 64 year old patient, consulting for a latero-cervical mass associated with dysphonia, dysphagia, and repeated vagal syncopes, evolving for 10 months.

Paragangliomas originating from blood vessels are exceptionally rare, presenting diagnostic challenges due to their histological resemblance to other vascular neoplasms. We present a case study of a 60-year-old woman with underlying hypertension and dyslipidemia with obesity, initially diagnosed with angiosarcoma based on imaging and histological characteristics viewed via CT-guided biopsy. Intraoperative exploration revealed a lobulated tumor located between the inferior vena cava (IVC) and aorta measuring 7 cm × 8 cm, during which the patient developed transient hemodynamic instabilities.

Rationale: Pheochromocytomas typically arise in the adrenal medulla, whereas ectopic pheochromocytomas/paragangliomas commonly occur near the abdominal aorta, bladder, mediastinum, and head. Diaphragmatic pheochromocytomas are exceedingly rare, and there is limited surgical experience with their treatment.
Patient Concerns: In Case A, the subject is a 45-year-old male, while in Case B, the subject is a 59-year-old female.

Phaeochromocytomas are rare catecholamine-secreting tumours, usually benign, originating from chromaffin cells of the adrenal glands. Their typical presentation includes the triad of headaches, sweating and tachycardia due to excessive catecholamine release. However, many patients do not exhibit all three symptoms, making diagnosis challenging.
