Topic: Pilomatrixoma
Question: What is (are) Pilomatrixoma ?
Answer: Pilomatrixoma is a benign (non-cancerous) skin tumor of the hair follicle (structure in the skin that makes hair). They tend to develop in the head and neck area and are usually not associated with any other signs and symptoms (isolated). Rarely, pilomatrixomas can become cancerous (known as a pilomatrix carcinoma). Although they can occur in people of all ages, pilomatrixomas are most commonly diagnosed in people under age 20. The exact underlying cause is not well understood; however, somatic changes (mutations) in the CTNNB1 gene are found in most isolated pilomatrixomas. Rarely, pilomatrixomas occur in people with certain genetic syndromes such as Gardner syndrome, myotonic dystrophy, and Rubinstein-Taybi syndrome; in these cases, affected people usually have other characteristic signs and symptoms of the associated condition. They are usually treated with surgical excision.

Answer: What are the signs and symptoms of Pilomatrixoma? The Human Phenotype Ontology provides the following list of signs and symptoms for Pilomatrixoma. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Pilomatrixoma - Somatic mutation - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

Question: What causes Pilomatrixoma ?
Answer: What causes a pilomatrixoma? The exact underlying cause of pilomatrixoma is not well understood. Changes (mutations) in the CTNNB1 gene are found in at least 75% of isolated (without other signs and symptoms) pilomatrixomas. These mutations are somatic, which means they are not inherited and are only present in the tumor cells. The CTNNB1 gene encodes a protein that is needed to regulate cell growth and attachment. When the gene is not working properly, it can result in abnormal cell growth. Rarely, pilomatrixomas occur in people with certain genetic syndromes such as Gardner syndrome, myotonic dystrophy, and Rubinstein-Taybi syndrome. In these cases, affected people usually have other characteristic features of the associated condition.

Topic: Pilomatrixoma
Question: Is Pilomatrixoma inherited ?
Answer: Is a pilomatrixoma inherited? Most isolated (without other signs and symptoms) pilomatrixomas are not inherited. However, more than one family member can rarely be affected, which suggests there may be a hereditary component in some cases. Rarely, pilomatrixomas occur in people with certain genetic syndromes such as Gardner syndrome, myotonic dystrophy, and Rubinstein-Taybi syndrome. In these cases, affected people usually have other characteristic signs and symptoms of the associated condition. All three of these conditions are inherited in an autosomal dominant manner. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family.

Question: How to diagnose Pilomatrixoma ?
Answer: How is a pilomatrixoma diagnosed? A diagnosis of pilomatrixoma is usually suspected on physical examination. Specialized tests may be ordered to confirm the diagnosis and rule out other conditions that cause similar features. These tests may include an ultrasound, an X-ray, and/or a small biopsy of the tumor.

Topic: Ewing's family of tumors
Question: What causes Ewing's family of tumors ?
Answer: What causes Askins tumor? In 80% to 90% of Askins tumors, a part of chromosome 11 and chromosome 22 are translocated. 'Translocation' means that the chromosomes have exchanged material. This exchange of material interrupts the cell's ability to grow and divide normally. In general, cancers are caused when the genes that regulate the cell's growth and division are changed. The cause of the changes is unknown, but may be due to a combination of genetic factors, environmental factors, and the process of aging. The development of cancer is not a quick or simple process. It is a progression involving a build-up of changes in a number of different genes in the cells of the body tissues over time.

Topic: Congenital contractural arachnodactyly
Question: What is (are) Congenital contractural arachnodactyly ?
Answer: Congenital contractural arachnodactyly (CCA) is a genetic disorder that is typically characterized by tall height; skinny, long limbs; long, skinny fingers and toes (arachnodactyly); multiple joint deformities present at birth (congenital contractures), usually of the elbows, knees, hips, fingers and ankles; "crumpled"-looking ears, and curvature of the spine (kyphoscoliosis). Other features might also be present and vary from person to person. CCA is caused by mutations in a gene called FBN2 gene and is inherited in an autosomal dominant pattern. CCA shares similiar signs and symptoms to Marfan syndrome; however, Marfan syndrome is not caused by mutations in the FBN2 gene.

Topic: Congenital contractural arachnodactyly
Question: What causes Congenital contractural arachnodactyly ?
Answer: What causes congenital contractural arachnodactyly? Congenital contractural arachnodactyly is caused by mutations in the FBN2 gene. The FBN2 gene provides instructions for producing the fibrillin-2 protein. Fibrillin-2 binds to other proteins and molecules to form threadlike filaments called microfibrils. Microfibrils become part of the fibers that provide strength and flexibility to connective tissue. Additionally, microfibrils hold molecules called growth factors and release them at the appropriate time to control the growth and repair of tissues and organs throughout the body. A mutation in the FBN2 gene can reduce the amount and/or quality of fibrillin-2 that is available to form microfibrils. As a result, decreased microfibril formation weakens the elastic fibers and allows growth factors to be released inappropriately, causing tall stature, deformities of the fingers and toes, and other characteristic features of congenital contractural arachnodactyly.

Topic: Congenital contractural arachnodactyly
Question: Is Congenital contractural arachnodactyly inherited ?
Answer: How is congenital contractural arachnodactyly inherited? This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits the mutation from an affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family.

Topic: Congenital contractural arachnodactyly
Question: What are the treatments for Congenital contractural arachnodactyly ?
Answer: How might congenital contractural arachnodactyly be treated? Physical therapy for joint contractures helps increase joint mobility and ameliorate the effects of muscle hypoplasia (usually in the calf muscles). In severe cases, surgical release may be necessary. Since the kyphosis/scoliosis tends to be progressive, bracing and/or surgical correction is often needed. Consultation with an orthopedist is encouraged. Other symptoms, if present, should be addressed as they arise and in the standard manner. Regular physician visits should be scheduled to monitor symptom progression and development.

Topic: Geographic tongue
Question: What is (are) Geographic tongue ?
Answer: Geographic tongue is a condition that causes chronic and recurrent lesions on the tongue that resemble psoriasis of the skin. It is characterized by pink to red, slightly depressed lesions with irregular, elevated, white or yellow borders. The lesions may also occur in the mucosa of the mouth and labia; this condition is called "areata migrans" because they  typically disappear from one area and move to another. The tongue is normally covered with tiny, pinkish-white bumps (papillae), which are actually short, fine, hair-like projections. With geographic tongue, patches on the surface of the tongue are missing papillae and appear as smooth, red "islands," often with slightly raised borders. These patches (lesions) give the tongue a map-like, or geographic, appearance. In most cases there are no symptoms but sometimes it is painful when inflamed. The cause is still unknown. Many researchers think it is linked with psoriasis but more research is needed to better understand the connection. Also, hereditary and environmental factors may be involved. The condition is benign and localized, generally requiring no treatment except reassurance. If painful it may be treated with steroid gels or antihistamine mouth rinses.[12267]

Topic: Geographic tongue
Question: What causes Geographic tongue ?
Answer: What causes geographic tongue? Is it genetic? The exact cause of geographic tongue has not been identified. However, because the condition may be present in several members of the same family, genetics may increase a person's chances of developing the condition. A study by Guimares (2007) showed that a specific variant of a gene called IL-1B (interleukin-1 beta) is associated with an increased risk of developing geographic tongue and suggests a genetic basis for the development of the disease. Further research may result in a better understanding of the genetic influences involved in the development of geographic tongue.

Question: What are the treatments for Geographic tongue ?
Answer: What treatment is available for geographic tongue? Because geographic tongue is a benign (harmless) condition and does not typically cause symptoms, treatment is usually unnecessary. Even those patients who experience sensitivity to hot or spicy foods, generally do not require treatment. With severe symptoms, topical corticosteroids, zinc supplements, and topical anesthetic rinses seem to reduce the discomfort in some patients.

Topic: Synovial Chondromatosis
Question: What is (are) Synovial Chondromatosis ?
Answer: Synovial chondromatosis is a type of non-cancerous tumor that arises in the lining of a joint. The knee is most commonly affected, however it can affect any joint. The tumors begin as small nodules of cartilage. These nodules can separate and become loose within the joint. Some tumors may be no larger than a grain of rice. Synovial chondromatosis most commonly occurs in adults ages 20 to 50. Signs and symptoms may include pain, swelling, a decreased range of motion, and locking of the joint. The exact underlying cause of the condition is unknown. Treatment may involve surgery to remove the tumor. Recurrence of the condition is common.

Topic: Synovial Chondromatosis
Question: What causes Synovial Chondromatosis ?
Answer: What causes synovial chondromatosis? The exact underlying cause of synovial chondromatosis is unknown. Some research suggests that trauma may play a role in its development because the condition primarily occurs in weight-bearing joints. Infection has also been considered as a contributing factor. The condition is not inherited. Synovial chondromatosis can reportedly occur as either a primary or secondary form. Primary synovial chondromatosis, which is more rare, occurs spontaneously and does not appear to relate to any pre-existing conditions. Secondary synovial chondromatosis is the more common form and often occurs when there is pre-existent osteoarthritis, rheumatoid arthritis, osteonecrosis, osteochondritis dissecans, neuropathic osteoarthropathy (which often occurs in diabetic individuals), tuberculosis, or osteochondral fractures (torn cartilage covering the end of a bone in a joint) in the affected individual.
