Symphalangism, distal, with microdontia, dental pulp stones, and narrowed zygomatic arch: A very rare syndrome characterized mainly by small teeth, underdeveloped wrist bones and fusion of the joints in the ends of the fingers.
Syncamptodactyly - scoliosis: A very rare disorder characterized by the association of a curved spine and partial webbing and permanent flexion of 2nd and 3rd toes
Syncopal paroxysmal tachycardia: Rapid heart rate that starts and ends suddenly and causes fainting.
Syndactyly is the most common congenital malformation of the limbs, with an incidence of 1 in 2000-3000 live births. Syndactyly can be classified as simple when it involves soft tissues only and classified as complex when it involves the bone or nail of adjacent fingers. It is a shared feature of more than 28 syndromes, including Poland, Apert, and Holt-Oram syndromes. Syndactyly is a failure of differentiation in which the fingers fail to separate into individual appendages. This separation usually occurs during the sixth and eighth weeks of embryologic development. The root words of the term syndactyly are derived from the Greek words syn, meaning together, and dactyly, meaning fingers or digits.
Syndactyly - cataract - mental retardation: A very rare syndrome characterized mainly by webbed fingers and toes, cataract and mental retardation
Syndactyly, Cenani Lenz type: A rare birth defect syndrome characterized by various hand bone abnormalities.
Syndactyly type 5: A birth defect involving webbed fingers and toes - usually between 3rd and 4th fingers and 2nd and 3rd toes.
Filippi syndrome is an extremely rare genetic disorder that may be apparent at birth (congenital). The disorder is characterized by an unusual facial appearance, abnormalities of the fingers and toes, and mild to severe mental retardation.
A birth defect involving webbing between the 3rd and 4th fingers as well as duplication of all or some of the fourth digit within the webbed tissue. The foot may also be involved with webbing between the 4th and 5th toe with an extra 5th toe in the webbed tissue.
A hand deformity where the fourth and fifth fingers are joined together by a web of tissue. In some cases, some or all of the adjoining bones in the two fingers may also be fused.
A birth defect involving webbed fingers and toes - usually between 3rd and 4th fingers and 2nd and 3rd toes. There is also fusion of some of the long bones in the hand (metacarpals) and feet (metatarsals)
A very rare syndrome characterized by webbing between the 1st and 2nd toes and extra little finger or part of the little finger. The earlobe also had a deep horizontal groove or a nodule. The big toe was also broad or duplicated.
A very rare syndrome characterized by the association of a cleft palate as well as the adhesion at birth of the upper and lower jaw by fibrous tissue.
A very rare syndrome characterized mainly by abnormal webbing inside the mouth, short stature, eye problems, mental retardation and small head, jaw, eyes and mouth.
A rare disorder involving the fusion of various joint bones in the hands and feet.
A rare inherited disorder characterized by short stature and fusion of the ankle (talus) bone and the heel bone (calcaneus).
A rare joint disorder where some of the tissue that lines the joint is replaced by bone-like tissue or cartilage. Usually only one joint is affected and it tends to be the knee, elbow or hip.
A synovial sarcoma is a rare form of cancer which usually occurs near to the joints of the arm, neck or leg. It is one of the soft tissue sarcomas. It is one of the rarest forms of soft tissue cancer in the world.
The name "synovial sarcoma" was coined early in the 20th century, as some researchers thought that the microscopic similarity of some tumors to synovium, and its propensity to arise adjacent to joints, indicated a synovial origin; however, the actual cells from which the tumor develops are unknown and not necessarily synovial.
Primary synovial sarcomas are most common in the soft tissue near the large joints of the arm and leg but have been documented in most human tissues and organs, including the brain, prostate, and heart.
Synovial sarcoma occurs most commonly in the young, representing about 8% of all soft tissue sarcomas but about 15-20% of cases in adolescents and young adults. The peak of incidence is before the 30th birthday and males are affected more often than females (ratio around 1.2:1).
Synovitis is the inflammation of a synovial (joint-lining) membrane, usually painful, particularly on motion, and characterized by swelling, due to effusion (fluid collection) in a synovial sac.
Syndrome consisting of synovitis, acne, palmoplantar pustulosis, hyperostosis, and osteitis (SAPHO). The most common site of the disease is the upper anterior chest wall, characterized by predominantly osteosclerotic lesions, hyperostosis, and arthritis of the adjacent joints. The association of sterile inflammatory bone lesions and neutrophilic skin eruptions is indicative of this syndrome. Source - Diseases Database
A very rare genetic disorder characterized by joint inflammation, inflammation of the uvea (layer between sclera and retina) and cranial neuropathy (damage to cranial nerves).
A sexually transmitted disease caused by a bacteria (Treponema pallidum). The condition is often asymptomatic in the early stages but one or more sores may be present in the early stages. Untreated syphilis usually results in remission of visible symptoms but further severe damage may occur to internal organs and other body tissues which can result in death.
Syphilitic aseptic meningitis is a complication of untreated syphilis that involves inflammation of the tissues covering the brain and spinal cord. The condition is marked by changes in mental status and problems with nerve function.
Alternative Names: Tabes dorsalis. Syphilitic myelopathy is a complication of untreated syphilis that involves muscle weakness and abnormal sensations.
Syringobulbia: A neurological disorder that progresses slowly and is characterized by a fluid filled cavity in the spinal cord and brain stem.
Syringocystadenoma papilliferum: A benign tumor that usually occurs on the face, neck or scalp. Malignancy and metastasis occurs very rarely. The tumor appears as a plaque, single bump or a row of bumps.
Syringomas - natal teeth - oligodontia: A very rare syndrome characterized by the presence of teeth at birth, missing teeth and a number of syringomas on the facial area. Syringomas are harmless tumors that form in sweat ducts.
