In addition, incompleteness of therapy is common, requiring multiple treatment sessions.Telangiectasias on the face are often treated with a laser. Laser therapy uses a light beam that is pulsed onto the veins in order to seal them off, causing them to dissolve. These light-based treatments require adequate heating of the veins. These treatments can result in the destruction of sweat glands, and the risk increases with the number of treatments. == References ==
Maffucci syndrome is a very rare disorder in which multiple benign tumors of cartilage develop within the bones (such tumors are known as enchondromas). The tumors most commonly appear in the bones of the hands, feet, and limbs, causing bone deformities and short limbs.It is named for the Italian pathologist Angelo Maffucci who described it in 1881. Fewer than 200 cases of this syndrome have been reported. Signs and symptoms
Patients are normal at birth and the syndrome manifests during childhood and puberty.The enchondromas affect the extremities and their distribution is asymmetrical. The most common sites of enchondromas are the metacarpal bones and phalanges of the hands. The feet are less commonly affected. Disfigurations of the extremities are a result. Pathological fractures can arise in affected metaphyses and diaphyses of the long bones and are common (26%). The risk for sarcomatous degeneration of enchondromas, hemangiomas, or lymphangiomas is 15–30% in the setting of Maffucci syndrome. Maffucci syndrome is associated with a higher risk of CNS, pancreatic, and ovarian malignancies. Multiple enchondromas may present in three disorders: Ollier disease, Maffucci syndrome, and metachondromatosis. It is important to make the distinction between these diseases, particularly Ollier disease and Maffucci syndrome. Ollier disease is more common than Maffucci syndrome, and presents with multiple enchondromas often in a unilateral distribution. However, hemangiomas and lymphangiomas are not seen in Ollier disease. Metachondromatosis demonstrates autosomal-dominant transmission and presents with both multiple osteochondromas and enchondromas.It is associated with multiple cavernous hemangioma and phlebolith. Lymphangiomas may also be apparent.
