Label	Id	Description
Atypical Endometrial Hyperplasia	NCIT_C4654	[An endometrial hyperplasia characterized by cytologic and architectural changes which may lead to endometrial carcinoma. Despite the atypical features and possible course, there is debate on whether to consider this a neoplasm. The relationship with endometrial intraepithelial neoplasia is also unclear.]
Rare Neoplastic Syndrome	NCIT_C35561	[A broad classification for uncommon disorders in which the development of neoplasms occur in association with a characteristic set of signs or symptoms. These disorders commonly have a genetic basis. The types of neoplasms themselves are not necessarily uncommon.]
Rare Disorder	NCIT_C4873	[A disease that affects fewer than 200,000 people in the United States.]
Neuroepithelial, Perineurial, and Schwann Cell Neoplasm	NCIT_C35562	[A morphologic category that includes neoplasms arising from cells that form and support the nervous system. Such neoplasms include neuroepithelial cell neoplasms and neoplasms that arise from the perineural sheaths (perineurial cell neoplasms and Schwann cell neoplasms). --2003]
Neoplasm by Morphology	NCIT_C4741	[A classification system grouping neoplasms according to their cellular characteristics.]
Nervous System Neoplasm	NCIT_C3268	[A benign or malignant, primary or metastatic neoplasm involving the central or peripheral nervous system.]
Rat Unclassifiable Benign Tumor	NCIT_C60527
Rat Unclassifiable Malignant Tumor	NCIT_C60528
Rat Uveal Leiomyoma	NCIT_C60529
Rat Tubulostromal Adenocarcinoma	NCIT_C60523
Tubulostromal Adenocarcinoma	NCIT_C80356	[A malignant ovarian epithelial tumor. It has been described in mice and rats and is characterized by marked pleomorphism, atypia, and an infiltrative growth pattern.]
Rat Tubulostromal Adenoma	NCIT_C60524
Tubulostromal Adenoma	NCIT_C79953	[A benign ovarian epithelial tumor. It has been described in mice and rats and is rare in other animal species. Morphologically it is characterized by the presence of tubular structures and interstitial stroma.]
Rat Tubulostromal Hyperplasia	NCIT_C60525
Adenocarcinoma Cell with Foamy Cytoplasm	NCIT_C60526
Childhood Botryoid-Type Embryonal Rhabdomyosarcoma of the Vagina	NCIT_C35556	[A morphologic variant of embryonal rhabdomyosarcoma occurring in female children. The neoplasm arises from the vagina. It is characterized by the formation of a cambium layer in the affected tissue and polypoid nodules with an abundant myxoid stroma.]
Childhood Botryoid-Type Embryonal Rhabdomyosarcoma	NCIT_C35574	[A morphologic variant of embryonal rhabdomyosarcoma occurring in children. The tumor arises from organs with a mucosal epithelial surface. It is characterized by the formation of a cambium layer in the affected tissue and polypoid nodules within an abundant myxoid stroma.]
Botryoid-Type Embryonal Rhabdomyosarcoma of the Vagina	NCIT_C40268	[A morphologic variant of embryonal rhabdomyosarcoma arising from the vagina. It is characterized by the formation of a cambium layer in the affected tissue and polypoid nodules within an abundant myxoid stroma.]
Metastatic Malignant Neoplasm to the Cervix	NCIT_C35557
Tall Cell Variant Thyroid Gland Papillary Carcinoma	NCIT_C35558	[A morphologic variant of papillary carcinoma of the thyroid gland characterized by the presence of tall malignant follicular cells, arranged in papillary and trabecular patterns. Necrotic changes and high mitotic activity are present.]
