A Rare First Presentation of Hodgkin's Lymphoma: Symptomatic Pericardial Effusion.

Symptomatic pericardial effusion occurring as the initial manifestation of Hodgkin's lymphoma is exceedingly uncommon, and there are limited documented instances in the available literature. Pericardial effusion can present various differential diagnoses, and among these, malignancy is an important yet less frequently encountered cause. A heightened level of suspicion is crucial for establishing an accurate diagnosis, particularly when the patient's clinical course deviates from the anticipated trajectory. Through this case, we aim to emphasize the significance of considering lymphoproliferative diseases as a pertinent possibility in the differential diagnosis of pericardial effusion. Additionally, we underscore the importance of promptly reaching a diagnosis, as it can help prevent severe complications and enhance the patient's prognosis.

Central Venous Catheter-Associated Superior Vena Cava Syndrome.

Superior vena cava syndrome (SVCS) is caused by any obstruction to the superior vena cava (SVC); the most common causes are malignancy and extrinsic compression. The use of medical devices, such as central venous catheters, poses an important risk factor, as they cause changes in the blood flow and in the vessel wall. This report describes a case of a 70-year-old male with an implantable central venous port, due to previous neoplastic disease, as the cause of the SVCS. Authors advise that the placement of medical devices ought to be carefully accessed and constantly revised to be removed when no longer needed to prevent avoidable complications.
