Label	Id	Description
Plasmacytoma	D010954	[Any discrete, presumably solitary, mass of neoplastic PLASMA CELLS either in BONE MARROW or various extramedullary sites.]
Platelet Storage Pool Deficiency	D010981	[Disorder characterized by a decrease or lack of platelet dense bodies in which the releasable pool of adenine nucleotides and 5HT are normally stored.]
Platybasia	D010985	[A developmental deformity of the occipital bone and upper end of the cervical spine, in which the latter appears to have pushed the floor of the occipital bone upward. (Dorland, 27th ed)]
Pleural Diseases	D010995	[Diseases involving the PLEURA.]
Pleural Effusion	D010996	[Presence of fluid in the pleural cavity resulting from excessive transudation or exudation from the pleural surfaces. It is a sign of disease and not a diagnosis in itself.]
Pleural Effusion, Malignant	D016066	[Presence of fluid in the PLEURAL CAVITY as a complication of malignant disease. Malignant pleural effusions often contain actual malignant cells.]
Pleural Neoplasms	D010997	[Neoplasms of the thin serous membrane that envelopes the lungs and lines the thoracic cavity. Pleural neoplasms are exceedingly rare and are usually not diagnosed until they are advanced because in the early stages they produce no symptoms.]
Pleurisy	D010998	[INFLAMMATION of PLEURA, the lining of the LUNG. When PARIETAL PLEURA is involved, there is pleuritic CHEST PAIN.]
Pleurodynia, Epidemic	D011000	[An acute, febrile, infectious disease generally occurring in epidemics. It is usually caused by coxsackieviruses B and sometimes by coxsackieviruses A; echoviruses; or other enteroviruses.]
Pleuropneumonia	D011001	[Inflammation of the lung parenchyma that is associated with PLEURISY, inflammation of the PLEURA.]
Pleuropneumonia, Contagious	D011002	[A pleuropneumonia of cattle and goats caused by species of MYCOPLASMA.]
Plummer-Vinson Syndrome	D011004	[A syndrome of DYSPHAGIA with IRON-DEFICIENCY ANEMIA that is due to congenital anomalies in the ESOPHAGUS (such as cervical esophageal webs). It is known as Patterson-Kelly syndrome in the United Kingdom.]
Pneumatosis Cystoides Intestinalis	D011006	[A condition characterized by the presence of multiple gas-filled cysts in the intestinal wall, the submucosa and/or subserosa of the INTESTINE. The majority of the cysts are found in the JEJUNUM and the ILEUM.]
Pneumocephalus	D011007	[Presence of air or gas within the intracranial cavity (e.g., epidural space, subdural space, intracerebral, etc.) which may result from traumatic injuries, fistulous tract formation, erosions of the skull from NEOPLASMS or infection, NEUROSURGICAL PROCEDURES, and other conditions.]
Pneumococcal Infections	D011008	[Infections with bacteria of the species STREPTOCOCCUS PNEUMONIAE.]
Pneumoconiosis	D011009	[A diffuse parenchymal lung disease caused by inhaled dust from processing SUGARCANE (bagasse), usually in the manufacturing of wallboard., A diffuse parenchymal lung disease caused by inhalation of dust and by tissue reaction to their presence. These inorganic, organic, particulate, or vaporized matters usually are inhaled by workers in their occupational environment, leading to the various forms (ASBESTOSIS; BYSSINOSIS; and others). Similar air pollution can also have deleterious effects on the general population.]
Pneumocystis Infections	D016720	[Infections with species in the genus PNEUMOCYSTIS, a fungus causing interstitial plasma cell pneumonia (PNEUMONIA, PNEUMOCYSTIS) and other infections in humans and other MAMMALS. Immunocompromised patients, especially those with AIDS, are particularly susceptible to these infections. Extrapulmonary sites are rare but seen occasionally.]
Pneumonia	D011014	[Infection of the lung often accompanied by inflammation., Inflammation of any part, segment or lobe, of the lung parenchyma.]
Pneumonia of Calves, Enzootic	D048089	[Chronic endemic respiratory disease of dairy calves and an important component of bovine respiratory disease complex. It primarily affects calves up to six months of age and the etiology is multifactorial. Stress plus a primary viral infection is followed by a secondary bacterial infection. The latter is most commonly associated with PASTEURELLA MULTOCIDA producing a purulent BRONCHOPNEUMONIA. Sometimes present are MANNHEIMIA HAEMOLYTICA; HAEMOPHILUS SOMNUS and mycoplasma species.]
Pneumonia of Swine, Mycoplasmal	D045729	[A chronic, clinically mild, infectious pneumonia of PIGS caused by MYCOPLASMA HYOPNEUMONIAE. Ninety percent of swine herds worldwide are infected with this economically costly disease that primarily affects animals aged two to six months old. The disease can be associated with porcine respiratory disease complex. PASTEURELLA MULTOCIDA is often found as a secondary infection.]
