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).
The symptoms of a sex-cord or stromal ovarian tumor can differ from other types of ovarian cancer. Common signs and symptoms include ovarian torsion, hemorrhage from or rupture of the tumor, an abdominal mass, and hormonal disruption. In children, isosexual precocious pseudopuberty may occur with granulosa cell tumors since they produce estrogen.
The term "germinoma" most often refers to a tumor in the brain that has a histology identical to two other tumors, dysgerminoma in the ovary and seminoma in the testis. [3] Since 1994, MeSH has defined germinoma as "a malignant neoplasm of the germinal tissue of the gonads , mediastinum , or pineal region" [ 4 ] and within its scope included ...
Ovarian tumors, or ovarian neoplasms, are tumors in the ovary. [1] Not all are ovarian cancer. [1] They consist of mainly solid tissue, while ovarian cysts contain fluid. [2]In 2020, the World Health Organization (WHO) divided ovarian tumours as 90% epithelial, 3% germ cell, and 2% sex cord-stromal types.
The ovarian disease has two forms, juvenile and adult, both characterized by indolent growth, [1] and therefore has high recovery rates. [2] [3] The staging system for these tumours is the same as for epithelial tumours and most present as stage I. [4] The peak age at which they occur is 50–55 years, but they may occur at any age.
International Histological Classification of Tumors The WHO Classification of Tumours , more commonly known as the WHO Blue Books , is a series of books that classify tumours . They are compiled by expert consensus and published by the World Health Organization 's (WHO) International Agency for Research on Cancer (IARC).
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 dysgerminoma is a type of germ cell tumor; [1] it usually is malignant and usually occurs in the ovary.. A tumor of the identical histology but not occurring in the ovary may be described by an alternate name: seminoma in the testis [2] or germinoma in the central nervous system or other parts of the body.
