A precancerous neoplastic process that affects the squamous, glandular, or transitional cell epithelium without evidence of invasion. According to the degree of nuclear atypia, number of mitotic figures, and presence of architectural distortion, it is classified as low grade (mild dysplasia) or high grade (moderate or severe dysplasia). [from NCI]

A malignant neoplasm originating from the surface ovarian epithelium. [from HPO]

A benign or malignant neoplasm that contains a single or multiple cystic spaces. Examples include cystadenoma, mucinous cystadenocarcinoma, and serous cystadenocarcinoma. [from NCI]

Ovarian cancer, the leading cause of death from gynecologic malignancy, is characterized by advanced presentation with loco-regional dissemination in the peritoneal cavity and the rare incidence of visceral metastases (Chi et al., 2001). These typical features relate to the biology of the disease, which is a principal determinant of outcome (Auersperg et al., 2001). Epithelial ovarian cancer is the most common form and encompasses 5 major histologic subtypes: papillary serous, endometrioid, mucinous, clear cell, and transitional cell. Epithelial ovarian cancer arises as a result of genetic alterations sustained by the ovarian surface epithelium (Stany et al., 2008; Soslow, 2008). [from OMIM]

A lesion in which the normally situated glands are partially or completely replaced by atypical cells with malignant characteristics. [from NCI]

Neoplasms containing cyst-like formations or producing mucin or serum. [from MONDO]

A benign or malignant neoplasm that affects the peritoneum. Representative examples of benign neoplasms include adenomatoid tumor and disseminated peritoneal leiomyomatosis. Representative examples of malignant neoplasms include primary peritoneal carcinoma, metastatic carcinoma to the peritoneum, and malignant mesothelioma. [from NCI]

A benign or malignant neoplasm affecting the fallopian tube. Representative examples of benign neoplasms include papilloma, adenofibroma, and leiomyoma. Representative examples of malignant neoplasms include carcinoma, carcinosarcoma, and adenosarcoma. [from NCI]

A non-neoplastic or neoplastic disorder that affects the fallopian tube. Representative examples of non-neoplastic disorders include salpingitis and endometriosis. Representative examples of neoplastic disorders include papilloma, adenofibroma, carcinoma, leiomyosarcoma, and carcinosarcoma. [from NCI]

A malignant epithelial neoplasm which is confined to the epithelial layer without evidence of further tissue invasion. [from NCI]

A rare, serous adenocarcinoma that arises from the lining of the peritoneum. It affects females. The clinical behavior and pathologic characteristics are similar to the serous adenocarcinoma that arises from the ovary. [from MONDO]

A malignant neoplasm involving the parametrium. [from MONDO]

A rare borderline or malignant epithelial tumor of the fallopian tube characterized by the presence of neoplastic epithelial cells that contain intracytoplasmic mucin and may resemble the epithelial cells of the endocervix or gastrointestinal tract. [from NCI]

An extremely rare adenocarcinoma that arises from the fallopian tube. It is characterized by the presence of neoplastic epithelial cells that contain intracytoplasmic mucin. The cases that have been reported are predominantly in situ mucinous adenocarcinomas. [from NCI]

An adenocarcinoma that arises from the fallopian tube. Histologic subtypes include clear cell, endometrioid, serous, and mucinous adenocarcinoma. It spreads to adjacent organs, regional lymph nodes, and peritoneum. [from NCI]

A rare benign neoplasm that arises from the mesothelial cells of the peritoneum. It is characterized by the presence of gland-like structures. Cytologic atypia is absent. [from NCI]

A group of rare uterine adnexal tumors comprising non-metastasizing neoplasms arising from the fallopian tube. This includes epithelial tumors (benign serous tumors such as serous adenofibroma and papilloma) and mature teratomas. Patients may be asymptomatic or present with tubal obstruction. [from ORDO]
