| congenital epulis of newborn | A congenital benign nodular tumour of the alveolar ridge, of unknown histogenesis; histologically, it is composed of large cells with a granular cytoplasm similar to that of a granular cell tumour (myoblastoma). (05 Mar 2000) |

| giant cell epulis | <dermatology, oncology> A non-neoplastic lesion characterised by a proliferation of granulation tissue containing numerous multinucleated giant cells. It occurs on the gingiva and alveolar mucosa (occasionally on other soft tissues) where it presents as a soft red-blue haemorrhagic nodular swelling. It also occurs within the mandible or maxilla as a unilocular or multilocular radiolucency. Peripheral giant cell granuloma refers to the gingiva (giant cell epulis), central refers to the jaw. Microscopically similar lesions occur in the tubular bones of the hands and feet, are considered neoplastic, and may have a malignant course. Identical bony lesions may be seen in hyperparathyroidism and cherubism. See: giant cell tumour of bone. Synonym: giant cell epulis. (05 Mar 2000) |
| pigmented epulis | A benign neoplasm of neuroectodermal origin that most often involves the anterior maxilla of infants in the first year of life. It presents clinically as a rapidly growing blue-black lesion producing a destructive radiolucency; histologically, it is characterised by small round undifferentiated tumour cells interspersed with larger polyhedral melanin-producing cells arranged in an alveolar configuration. Synonym: melanoameloblastoma, pigmented ameloblastoma, pigmented epulis, progonoma of jaw, retinal anlage tumour. (05 Mar 2000) |
| epulis | A tumour on the gingivae. (27 Sep 1997) |
| epulis fissuratum | Overgrowth of tissue in the mucobuccal or labial fold, induced by chronic trauma from ill-fitting dentures. Synonym: denture hyperplasia, epulis fissuratum. (05 Mar 2000) |
| epulis gravidarum | A gingival pyogenic granuloma that develops during pregnancy. (05 Mar 2000) |
| ABO haemolytic disease of the newborn | Erythroblastosis foetalis due to maternal-foetal incompatibility with respect to an antigen of the ABO blood group; the foetus possesses A or B antigen which is lacking in the mother, and the mother produces immune antibody which causes haemolysis of foetal erythrocytes. (05 Mar 2000) |
| bullous impetigo of newborn | Usually, widely disseminated bullous lesions appearing soon after birth, caused by infection with Staphylococcus aureus. Synonym: impetigo neonatorum, pemphigus gangrenosus. (05 Mar 2000) |
| respiratory distress syndrome of the newborn | A disease seen especially in premature neonates with respiratory distress; characterised postmortem by atelectasis and alveolar ducts lined by an eosinophilic membrane; also associated with reduced amounts of lung surfactant. Synonym: hyaline membrane syndrome, respiratory distress syndrome of the newborn. (05 Mar 2000) |
| pleural effusion in newborn | <radiology> Chylothorax most common cause of large effusion, erythroblastosis foetalis, Turner syndrome, congestive heart failure, infantile polycystic kidneys, wet-lung disease, hypervolaemia (idiopathic or iatrogenic), oesophageal tear, enteric cyst, obstructed pulmonary veins (12 Dec 1998) |
| postnatal pit of the newborn | It marks the site where the embryonic spinal cord attaches to the skin. Synonym: postnatal pit of the newborn. (05 Mar 2000) |
| haemolytic anaemia of newborn | <haematology> A condition which develops in the foetus due to an incompatibility between the mother's blood type (RH factor) and the baby's. Maternal antibodies, which enter the foetal circulation during delivery attack the baby's red blood cells leading to haemolysis (rupture of the cells). Symptoms include an infant with an enlarged liver and spleen, swelling, jaundice and anaemia. (27 Sep 1997) |

| haemolytic disease of the newborn | Abnormal breakup of red blood cells in the foetus or newborn. This is usually due to antibodies made by the mother directed against the baby's red cells. It is typically caused by rh incompatibility, that is differences between the mother and baby uinvolving the rh blood group. (12 Dec 1998) |
| haemorrhagic disease of newborn | A self-limited haemorrhagic disorder of the first days of life, caused by a deficiency of the vitamin k-dependent blood coagulation factors II, vii, ix, and x. (12 Dec 1998) |
