|---|---|---|---|
| 설명 | 자기 복제를 하여 자신을 존속시키면서 한편으로는 증식과 분화를 하여 새로운 세포를 형성하는 세포로서 조혈줄기세포가 대표적이다. 조혈줄기세포는 골수에 있는 세포로서 모든 혈구세포가 여기에서 분화되어 발생한다. |

| 영문 | renal cell carcinoma | 한글 | 콩팥세포암종 |
|---|---|---|---|
| 설명 | 콩팥에 생긴 원시콩팥조직에서 발생한 암. 주로 원시세뇨관조직에서 발생한다. 대표적인 세포조직형은 염색시 세포질이 맑게 비어보이는 맑은세포암종이다. 치료는 수술과 항암화학요법이며 아주 드물지만 저절로 낫는 경우도 있는 것으로 보고되어 있다. |

|---|---|---|---|
| 설명 | 편평세포 기원의 암으로서, 편평세포가 있는 어떤 곳에서든 발생가능함. 따라서 식도암, 피부암, 폐암, 자궁암 등이 여기에 해당된다. 특히 피부암은 많은 자외선조사에 의해 생기는 광선각화증에서 발생가능하다. 병리조직학적 특성으로서 각질을 생성한다. |

| 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) |

| carcinoma, non-small-cell lung | A heterogeneous aggregate of at least three distinct histological types of lung cancer, including squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. They are dealt with collectively because of the shared properties of poor response to conventional chemotherapy and the potential for cure with surgical resection in a fraction of patients. (12 Dec 1998) |
| carcinoma, small cell | An anaplastic, highly malignant, and usually bronchogenic carcinoma composed of small ovoid cells with scanty neoplasm. It is characterised by a dominant, deeply basophilic nucleus, and absent or indistinct nucleoli. There are admixtures of small cell lung carcinoma with other types of lung cancer. Small cell carcinomas are distinguished by their distinctive biological features, response to chemotherapy and radiotherapy, and by their nearly universal tendency to develop overt or subclinical metastases, which frequently eliminates surgery in most patients. (12 Dec 1998) |
| sarcoma, small cell | A sarcoma characterised by the presence of small cells, cells measuring 9-14 micrometers with a faint or indistinct rim of cytoplasm and an oval-to-elongated nucleus with relatively dense chromatin. (12 Dec 1998) |
| small cell carcinoma | <oncology, tumour> Common malignant neoplasm of bronchus. Cells of the tumour have endocrine like characteristics and may secrete one or more of a wide range of hormones, especially regulatory peptides like bombesin. (18 Nov 1997) |
| small cell lung cancer | A type of lung cancer in which the cells are small and round. Also called oat cell lung cancer. (12 Dec 1998) |
| benign lymphoma of the rectum | A rectal polyp composed of lymphoid tissue with follicle formation, covered by mucosa. (05 Mar 2000) |
| burkitt lymphoma | A form of undifferentiated malignant lymphoma usually found in central africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumour in virtually all cases of burkitt lymphoma. The epstein-barr virus (herpes virus 4, human) has been isolated from burkitt lymphoma cases in africa and it is implicated as the causative agent in these cases; however, most non-african cases are ebv-negative. (12 Dec 1998) |
| Burkitt's lymphoma | <oncology, tumour> A type of Non-Hodgkin lymphoma that most often occurs in young people between the ages of 12 and 30. The disease usually causes a rapidly growing tumour in the abdomen. (12 May 1997) |
| cancer, lymphoma, hodgkin's | A type of lymphoma (cancer of the lymphatic system). The most common symptom of Hodgkin's disease is a painless swelling in the lymph nodes in the neck, underarm, or groin. Hodgkin's disease is diagnosed when abnormal tissue is detected by a pathologist after a biopsy of an enlarged lymph node. Treatment usually includes radiation therapy or chemotherapy. Regular follow-up examinations are important after treatment for Hodgkin's disease. Patients treated for Hodgkin's disease have an increased risk of developing other types of cancer later in life, especially leukaemia. (12 Dec 1998) |
| cancer, lymphoma, non-hodgkin's | A lymphoma is a cancer that develops in the lymphatic system. The most common symptom of non-Hodgkin's lymphomas is a painless swelling in the lymph nodes in the neck, underarm, or groin. Non-Hodgkin's lymphomas are diagnosed with a biopsy of an enlarged lymph node. Follow-up examinations are important after lymphoma treatment. Most relapses occur in the first 2 years after therapy. (12 Dec 1998) |
| canine malignant lymphoma | <tumour> A progressive fatal disease of dogs characterised by neoplastic transformation and proliferation of lymphoid cells, usually originating in solid lymphoid organs (lymphosarcoma) or bone marrow (lymphocytic leukaemia). (05 Mar 2000) |
| malignant lymphoma | <tumour> A general term for ordinarily malignant neoplasms of lymphoid and reticuloendothelial tissues which present as apparently circumscribed solid tumours composed of cells that appear primitive or resemble lymphocytes, plasma cells, or histiocytes. Lymphomas appear most frequently in lymph nodes, spleen, or other normal sites of lymphoreticular cells; when disseminated, Lymphoma's, especially of the lymphocytic type, may invade the peripheral blood and manifest as leukaemia. Lymphomas are classified by cell type, degrees of differentiation, and nodular or diffuse pattern; Hodgkin's disease and Burkitt's lymphoma are special forms. (05 Mar 2000) |
| Mediterranean lymphoma | A spectrum of conditions ranging from a benign plasma cell hyperplasia to a highly malignant lymphoma of the small intestine. (12 Dec 1998) |
| well-differentiated lymphocytic lymphoma | <tumour> Essentially the same disease as chronic lymphocytic leukaemia, except that lymphocytes are not increased in the peripheral blood; lymph nodes are enlarged and other lymphoid tissue or bone marrow is infiltrated by small lymphocytes. Synonym: small lymphocytic lymphoma. (05 Mar 2000) |
