| lymphoma, T-cell, peripheral | A group of malignant lymphomas thought to derive from peripheral T-lymphocytes in lymph nodes and other nonlymphoid sites. They include a broad spectrum of lymphocyte morphology, but in all instances express T-cell markers admixed with epithelioid histiocytes, plasma cells, and eosinophils. Although markedly similar to large-cell immunoblastic lymphoma (lymphoma, large-cell, immunoblastic), this group's unique features warrant separate treatment. (12 Dec 1998) |

| alimentary tract smear | A group of cytologic specimens containing material from the mouth (oral smear), oesophagus and stomach (gastric smear), duodenum (paraduodenal smear), and colon, obtained by specialised lavage techniques; used principally for the diagnosis of cancer of those areas. (05 Mar 2000) |
| blood smear | A sample of blood is applied to a microscope slide and then studied under the microscope. Red blood cell appearance and differential is analysed. Red blood size, shape and colour are commented on. Conditions such as hereditary spherocytosis, haemolytic anaemia, sickle cell anaemia, TTP, DIC, thalassaemia, pernicious anaemia, myelodysplasia, G6PD deficiency and lymphomas. (27 Sep 1997) |
| bronchoscopic smear | A group of cytologic specimens containing material from the lower respiratory tract and consisting mainly of sputum (spontaneous, induced) and material obtained at bronchoscopy (aspirated, lavaged, brushed); used for cytologic study of cancer and other diseases of the lungs. Synonym: bronchoscopic smear, sputum smear. (05 Mar 2000) |
| buccal smear | A cytologic smear containing material obtained by scraping the lateral buccal mucosa above the dentate line, smearing, and fixing immediately; used principally for determining somatic sex as indicated by the presence of the sex chromocenter (Barr body). (05 Mar 2000) |
| vaginal smear | A smear of debris from the vaginal lumen of mammals, used to determine the stage of their reproductive cycle. It is most useful in subprimate mammals having short estrous cycles; nucleated epithelial cells and leukocytes prevail in the smear during diestrus and proestrus, and cornified cells during estrus. (05 Mar 2000) |
| pancervical smear | A cytologic smear of material obtained from the endocervical canal, external os, and ectocervix by scraping these areas with a properly designed cervical spatula; used principally for early cervical cancer detection. (05 Mar 2000) |
| gastric smear | A group of cytologic specimens containing material from the mouth (oral smear), oesophagus and stomach (gastric smear), duodenum (paraduodenal smear), and colon, obtained by specialised lavage techniques; used principally for the diagnosis of cancer of those areas. (05 Mar 2000) |
| VCE smear | A cytologic smear of material obtained from the vagina, ectocervix, and endocervix, smeared separately (in that order) on one slide, and fixed immediately; used principally for the detection of cervical cancer and identification of the sites of diseases of those areas, and for hormonal evaluation. (05 Mar 2000) |
| Papanicolaou smear | (Papanicolao) a special stain performed usually on a smear taken from the neck of the womb - the cervix. (16 Dec 1997) |
| Papanicolaou smear test | Microscopic examination of cells collected from the cervix. It is used to detect changes that may be cancer or may lead to cancer, and it can show noncancerous conditions, such as infection or inflammation. Also called pap smear. (12 Dec 1998) |
| pap smear | (Papanicolao) a special stain performed usually on a smear taken from the neck of the womb - the cervix. (16 Dec 1997) |
| cervical smear | Cytological staining procedure for detecting and diagnosing various conditions, especially malignant and pre-malignant conditions of the cervix. (16 Dec 1997) |
| colonic smear | A group of cytologic specimens containing material from the mouth (oral smear), oesophagus and stomach (gastric smear), duodenum (paraduodenal smear), and colon, obtained by specialised lavage techniques; used principally for the diagnosis of cancer of those areas. (05 Mar 2000) |
| cul-de-sac smear | A cytologic specimen of material obtained by aspirating the pouch of Douglas from the posterior vaginal fornix and prepared by smearing, centrifuging, or filtering; used principally for ovarian cancer. (05 Mar 2000) |
