Sarcoma

Your soft tissues connect, support, or surround other tissues. Examples include your muscles, tendons, fat, and blood vessels. Soft tissue sarcoma is a cancer of these soft tissues. There are many kinds, based on the type of tissue they started in. They may cause a lump or swelling in the soft tissue. Sometimes they spread and can press on nerves and organs, causing problems such as pain or trouble breathing. No one knows exactly what causes these cancers. They are not common, but you have a higher risk if you have been exposed to certain chemicals, have had radiation therapy, or have certain genetic diseases. Doctors diagnose soft tissue sarcomas with a biopsy. Treatments include surgery to remove the tumor, radiation therapy, chemotherapy, or a combination.

Malignant rhabdoid tumor

A malignant tumor of either the central nervous system (CNS) or the kidney. Malignant rhabdoid tumors of the CNS often have an abnormality of chromosome 22. These tumors usually occur in children younger than 2 years. [from NCI]

Medulloblastoma

Medulloblastoma is the most common brain tumor in children. It accounts for 16% of all pediatric brain tumors, and 40% of all cerebellar tumors in childhood are medulloblastoma. Medulloblastoma occurs bimodally, with peak incidences between 3 and 4 years and 8 and 9 years of age. Approximately 10 to 15% of medulloblastomas are diagnosed in infancy. Medulloblastoma accounts for less than 1% of central nervous system (CNS) tumors in adults, with highest incidence in adults 20 to 34 years of age. In 1 to 2% of patients, medulloblastoma is associated with Gorlin syndrome (109400), a nevoid basal carcinoma syndrome. Medulloblastoma also occurs in up to 40% of patients with Turcot syndrome (276300). Medulloblastoma is thought to arise from neural stem cell precursors in the granular cell layer of the cerebellum. Standard treatment includes surgery, chemotherapy, and, depending on the age of the patient, radiation therapy (Crawford et al., 2007). [from OMIM]

Medulloblastoma

A rapidly growing embryonic tumor arising in the posterior part of the `cerebellar vermis` (FMA:76928) and neuroepithelial roof of the fourth ventricle in children. More rarely, medulloblastoma arises in the `cerebellum` (FMA:67944) in adults. [from HPO]

Atypical teratoid/rhabdoid tumor

An aggressive malignant embryonal neoplasm arising from the central nervous system. It is composed of cells with a large eccentric nucleus, prominent nucleolus, and abundant cytoplasm. It may be associated with loss of chromosome 22. The vast majority of cases occur in childhood. Symptoms include lethargy, vomiting, cranial nerve palsy, headache, and hemiplegia. [from NCI]

Ewing's sarcoma

Ewing sarcoma is a cancerous tumor that occurs in bones or soft tissues, such as cartilage or nerves. There are several types of Ewing sarcoma, including Ewing sarcoma of bone, extraosseous Ewing sarcoma, peripheral primitive neuroectodermal tumor (pPNET), and Askin tumor. These tumors are considered to be related because they have similar genetic causes. These types of Ewing sarcoma can be distinguished from one another by the tissue in which the tumor develops. Approximately 87 percent of Ewing sarcomas are Ewing sarcoma of bone, which is a bone tumor that usually occurs in the thigh bones (femurs), pelvis, ribs, or shoulder blades. Extraosseous (or extraskeletal) Ewing sarcoma describes tumors in the soft tissues around bones, such as cartilage. pPNETs occur in nerve tissue and can be found in many parts of the body. A type of pPNET found in the chest is called Askin tumor. Ewing sarcomas most often occur in children and young adults. Affected individuals usually feel stiffness, pain, swelling, or tenderness of the bone or surrounding tissue. Sometimes, there is a lump near the surface of the skin that feels warm and soft to the touch. Often, children have a fever that does not go away. Ewing sarcoma of bone can cause weakening of the involved bone, and affected individuals may have a broken bone with no obvious cause. It is common for Ewing sarcoma to spread to other parts of the body (metastasize), usually to the lungs, to other bones, or to the bone marrow.

Neuroectodermal Tumor, Primitive

A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant.

Retinitis pigmentosa

Retinitis pigmentosa (RP) is a group of inherited disorders in which abnormalities of the photoreceptors (rods and cones) or the retinal pigment epithelium (RPE) of the retina lead to progressive visual loss. Affected individuals first experience defective dark adaptation or "night blindness," followed by constriction of peripheral visual fields and, eventually, loss of central vision late in the course of the disease. [from GeneReviews]
