The International Classification of Childhood Cancer (ICCC) is a standardized method for categorizing childhood malignancies set forth by the World Health Organization (WHO). This system bases malignancy classification on the histological traits of the tumor (type of tissue). This is opposed to the classification of adult malignancies, which ...
Embryonal rhabdomyosarcoma. Embryonal rhabdomyosarcoma ( EMRS) is a rare histological form of cancer in the connective tissue wherein the mesenchymally-derived cells ( rhabdomyoblasts) resemble the primitive developing skeletal muscle of the embryo. It is the most common soft tissue sarcoma occurring in children. [ 1]
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
A 2007 study based on 12 cases from the Faroe Islands (where there is a relatively high incidence due to a founder effect) suggested that the outcome is often poor with early lethality. [18] More recent studies (2015) with 50 people with SUCLA2 mutations, with range of 16 different mutations, show a high variability in outcomes with a number of ...
Atypical teratoid rhabdoid tumor. An atypical teratoid rhabdoid tumor ( AT/RT) is a rare tumor usually diagnosed in childhood. Although usually a brain tumor, AT/RT can occur anywhere in the central nervous system (CNS), including the spinal cord. About 60% will be in the posterior cranial fossa (particularly the cerebellum ).
The diagnosis was post-auricular congenital alveolar rhabdomyosarcoma. Rhabdomyosarcoma ( RMS) is a highly aggressive form of cancer that develops from mesenchymal cells that have failed to fully differentiate into myocytes of skeletal muscle. Cells of the tumor are identified as rhabdomyoblasts. [ 1]
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [ 1] Work on ICD-10 began in 1983, [ 2 ...
Prolactinoma. A prolactinoma is a tumor ( adenoma) of the pituitary gland that produces the hormone prolactin. It is the most common type of functioning pituitary tumor. [ 1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood ( hyperprolactinemia ), or due to pressure of the tumor on surrounding brain tissue ...
