Superior vena cava syndrome ( SVCS ), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulating blood into the heart. The majority of cases are caused by malignant tumors within the mediastinum, most commonly lung cancer and non-Hodgkin's lymphoma, directly compressing or invading ...
Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance. [ 2]: 826–7 [ 3] Superficial thrombophlebitis is due to inflammation and/or thrombosis, and,less commonly, infection of the vein.
Hereditary angioedema (HAE) is a disorder that results in recurrent attacks of severe swelling. [3] The swelling most commonly affects the arms, legs, face, intestinal tract, and airway. [3] If the intestinal tract is affected, abdominal pain and vomiting may occur. [1] Swelling of the airway can result in its obstruction and trouble breathing. [1]
Thoracic outlet syndrome ( TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. [ 1] There are three main types: neurogenic, venous, and arterial. [ 1] The neurogenic type is the most common and ...
Angioedema is an area of swelling ( edema) of the lower layer of skin and tissue just under the skin or mucous membranes. [ 1][ 3] The swelling may occur in the face, tongue, larynx, abdomen, or arms and legs. [ 1] Often it is associated with hives, which are swelling within the upper skin. [ 1][ 3] Onset is typically over minutes to hours.
Complex regional pain syndrome is a multifactorial disorder with clinical features of neurogenic inflammation (inflammation mediated by nerve cells), nociceptive sensitisation (which causes extreme sensitivity or allodynia), vasomotor dysfunction (blood flow problems which cause swelling and discolouration) and maladaptive neuroplasticity ...
Rheumatology. Remitting seronegative symmetrical synovitis with pitting edema (or sometimes RS3PE) is a rare syndrome identified by symmetric polyarthritis, synovitis, acute pitting edema (swelling) of the back of the hands and/or feet, and a negative serum rheumatoid factor. [ 2] If no underlying disorder can be identified ( idiopathic RS3PE ...
There are also a number of other conditions that affect hands, feet, and parts of the face with associated skin color changes that need to be differentiated from acrocyanosis: Raynaud phenomenon, pernio, acrorygosis, erythromelalgia, and blue finger syndrome. The diagnosis may be challenging in some cases, especially when these syndromes co-exist.
