Felty's syndrome as an initial presentation of rheumatoid arthritis: a case report.

Introduction: Felty's syndrome is an uncommon but severe extra-articular manifestation of rheumatoid arthritis. Felty's syndrome is characterized by the triad of rheumatoid arthritis, neutropenia, and splenomegaly. The lifetime risk of Felty's syndrome for a rheumatoid arthritis patient is less than 1% and there are only few case reports of Felty's syndrome with neutropenia preceded clinical evidence of arthritis.

Superior vena cava syndrome (SVC syndrome): a rare cause of conjunctival suffusion.

Obstruction of blood flow in the superior vena cava results in the signs and symptoms of superior vena cava (SVC) syndrome. Venous collaterals form, to establish alternative pathways for return of venous blood to the right atrium. The rapidity of onset of symptoms and signs from SVC obstruction is directly related to the rate at which obstruction occurs and how effective the formed collaterals are.
