Nervous tissue neoplasm
|
HP_0030060 |
[A neoplasm derived from nervous tissue (not necessarily a neoplasm located in the nervous system).] |
|
Neuroectodermal neoplasm
|
HP_0030061 |
[A neoplasm arising in the neuroectoderm, the portion of the ectoderm of the early embryo that gives rise to the central and peripheral nervous systems, including some glial cells.] |
|
Olfactory esthesioneuroblastoma
|
HP_0030068 |
[A malignant olfactory neuroblastoma arising from the olfactory epithelium of the superior nasal cavity and cribriform plate.] |
|
Neuroblastoma
|
HP_0003006 |
[Neuroblastoma is a solid tumor that originate in neural crest cells of the sympathetic nervous system. Most neuroblastomas originate in the abdomen, and most abdominal neuroblastomas originate in the adrenal gland. Neuroblastomas can also originate in the thorax, usually in the posterior mediastinum.] |
|
Primary central nervous system lymphoma
|
HP_0030069 |
[A form of extranodal, high-grade non-Hodgkin B-cell neoplasm, usually large cell or immunoblastic type that originates in the brain, leptomeninges, spinal cord, or eyes and typically remains confined to the CNS.] |
|
Ependymoblastoma
|
HP_0030066 |
[A highly malignant embryonal tumor of infancy and young childhood characterized by neuroectodermal elements organized in distinctive multilayered rosettes. Ependymoblastomas are large lesions that occur in the supratentorial compartment, typically displaying a physical connection to the ventricular system.] |
|
Central primitive neuroectodermal tumor
|
HP_0030070 |
[A primitive neuroectodermal neoplasm that occurs in the central nervous system.] |
|
Peripheral primitive neuroectodermal neoplasm
|
HP_0030067 |
[A primitive neuroectodermal neoplasm that occurs extracranially in soft tissue and bone.] |
|
Primitive neuroectodermal tumor
|
HP_0030065 |
[A tumor that originates in cells from the primitive neural crest. This group of tumors is characteirzed by the presence of primitive cells with elements of neuronal and/or glial differentiation.] |
|
Neurocytoma
|
HP_0030064 |
[A benign brain tumor composed of neural elements which most often arise from the septum pellucidum and the walls of the lateral ventricles.] |
|
Craniopharyngioma
|
HP_0030062 |
[A benign pituitary-region neoplasm that originates from Rathke's pouch. Craniopharyngiomas are benign slow growing tumors that are located within the sellar and para sellar region of the central nervous system.] |
|
obsolete Narcolepsy
|
HP_0030050 |
|
|
positive regulation of antigen processing and presentation of peptide or polysaccharide antigen via MHC class II
|
GO_0002582 |
[Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation of antigen (peptide or polysaccharide) via MHC class II.] |
|
positive regulation of antigen processing and presentation
|
GO_0002579 |
[Any process that activates or increases the frequency, rate, or extent of antigen processing and presentation.] |
|
regulation of antigen processing and presentation of peptide or polysaccharide antigen via MHC class II
|
GO_0002580 |
[Any process that modulates the frequency, rate, or extent of antigen processing and presentation of antigen (peptide or polysaccharide) via MHC class II.] |
|
Sickled erythrocytes
|
HP_0030058 |
[An irreversible distortion of the morphology of an erythrocyte such that the cells are elongated and curved, resembling the blade of a sickle (the hand-held agricultural tool traditionally used to harvest grains).] |
|
negative regulation of antigen processing and presentation of peptide or polysaccharide antigen via MHC class II
|
GO_0002581 |
[Any process that stops, prevents, or reduces the frequency, rate, or extent of antigen processing and presentation of antigen (peptide or polysaccharide) via MHC class II.] |
|
negative regulation of antigen processing and presentation
|
GO_0002578 |
[Any process that stops, prevents, or reduces the frequency, rate, or extent of antigen processing and presentation.] |
|
Hyperconvex toenail
|
HP_0030055 |
[When viewed on end (with the tip of the toe pointing toward the examiner's eye) the curve of the toenail forms a tighter curve of convexity.] |
|
Hyperconvex nail
|
HP_0001795 |
[When viewed on end (with the digit tip pointing toward the examiner's eye) the curve of the nail forms a tighter curve of convexity.] |
