Obuense, m. Gilvum, m. Duvali, m. Szulgai, m. Intracellulare (see mycobacterium avium complex), m. Xenopi (littorale), m. Ulcerans, m. Buruli, m. Terrae, m. Fortuitum (minetti, giae), m. Chelonae.

| primary atypical pneumonia | An acute systemic disease with involvement of the lungs, caused by Mycoplasma pneumoniae and marked by high fever, cough, relatively few physical signs, and scattered densities on X-rays; usually associated with development of cold agglutinins and antibodies to the bacteria. Synonym: atypical pneumonia, Eaton agent pneumonia, mycoplasmal pneumonia. (05 Mar 2000) |
| adult T-cell lymphoma | <tumour> An acute or subacute disease associated with a human T-cell virus, with lymphadenopathy, hepatosplenomegaly, skin lesions, peripheral blood involvement, and hypercalcaemia. Synonym: adult T-cell leukaemia. (05 Mar 2000) |
| anaplastic large cell lymphoma | <tumour> A form of lymphoma characterised by anaplasia of cells, sinusoidal growth, and immunoreactivity with CD30 (Ki-1 or Ber-H2). Synonym: Ki-1+ lymphoma. (05 Mar 2000) |
| 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.
