  Malignant - Wikipedia, the free encyclopedia
In medicine, malignant is a clinical term that is used to describe a clinical course that progresses rapidly to death.
Malignant transformation is a synonym for progression to malignancy.
Although malignant transformation may occur because of changes within the cell, it can be induced by inorganic toxic substances such as cadmium or arsenite and organics such as tobacco-specific nitrosamines.

 Hematological malignancy   (Site not responding. Last check: 2007-09-17)
Although hematological malignancies are a form of cancer, they aregenerally treated by specialists in hematology, although in many hospitals oncology specialists also manage these diseases.
Hematological malignancies are the types cancer that affect blood, bone marrow and lymph nodes.
As the three are intimately connected through the immune system, a disease affecting one of the three will often affect the othersas well: although lymphoma is technically a lymph node disease, it often spreads to the bone marrow,affecting the blood and occasionally producing a paraprotein.

 CHEST: Linkage analysis of malignancy-associated sarcoidosis   (Site not responding. Last check: 2007-09-17)
That sarcoidosis is more attended by malignancy than expected by chance has been in dispute since the seminal article by Brincker and Wilbek[1] in which they found an excess of lung cancer and lymphoma-associated cases when crossmatching a national respiratory sarcoidosis registry comprising 2,561 subjects against a malignancy registry compiled by the Danish national government.
An excess of malignancy was observed in the group with sarcoidosis: 22 of 43 (51%) had died of malignancy (90%; confidence interval [CI], 38.5 to 63.5) vs "slightly less than 40%" of the entire autopsied population.
Fourth, misclassification in either direction--ie, sarcoidosis as malignancy or malignancy as sarcoidosis--is highly problematic in sarcoidosis, a disorder lacking a sensitive and specific diagnostic marker, particularly in the setting of lymphohematogenous neoplasia, which can both mimic and be mimicked by sarcoidosis.

 News - Malignancy Risks Higher In Patients With Severe Psoriasis
Patients with severe psoriasis are at increased risk of developing a malignancy, especially non-melanoma skin cancers and lymphoma.
They compared the risk of malignancy for individuals with psoriasis of varying severity with patients who had severe eczema, those who had had organ transplants and hypertension patients placed in a reference group.
They also estimated the malignancy risk in organ transplant patients "to obtain a benchmark for rates that are likely to be associated with the use of immunosuppressive medications, many of which are used or might be used in the future to treat psoriasis."

The researchers found that 134 (2.8%) of those with celiac disease had at least one malignancy, and 237 (5.0%) had died.
The researchers conclude that there is a modest increase in the rates of malignancy and mortality during the first year following a diagnosis of celiac disease.
After one year, however, most of that increase quickly diminishes to a level that is only slightly higher than that of the normal population, presumably due to the effects of a gluten-free diet.

 A LOGISTIC REGRESSION MODEL TO PREDICT NODAL MALIGNANCY AMONG CASES WITH LYMPHADENOPATHY
The association of malignancy and age was direct, meaning that the increase in age was associated with a greater likelihood of malignancy (P=0.004).
The increased probability of malignancy with hard nodes in elderly patients can be explained by the fact that malignancy increases with age, and the chance for a hard node to be malignant is higher in elderly than in young patients.
When assessing the validity of such a clinical prediction of nodal malignancy, it was found that a specificity of 74% was detected at a cut-off value of probability of 0.40, a finding that results in 26% of cases doing an unnecessary biopsy, based on these clinical criteria.

Fine needle aspiration biopsy was specifically diagnostic of squamous carcinoma in 33 cases; the exact type of malignant cell could not be determined in the other four (three metastatic from poorly differentiated nasopharyngeal squamous carcinoma, one metastatic from parotid squamous carcinoma) because the cells were too poorly differentiated.
Excluding the six cases with inadequate samples, therefore, FNAB was considered not to be suspicious for malignancy in 75% of cases of reactive or inflammatory swellings, and inconclusive in 25%.
Most malignant neck lumps which were incorrectly diagnosed by FNAB in the present study were cystic, and 25% of cystic lateral neck lumps not considered to be suspicious for malignancy turned out to be malignant.

 IMMUNODEFICIENCY, AUTOIMMUNITY, AND MALIGNANCY
Studies performed over the last two decades have demonstrated an increased incidence of malignancy in primary immunodeficiency diseases; however, it has also become clear that the concept of immune surveillance cannot be fully accepted on the evidence from these studies.
The types of malignancy that occur as a complication of some immunodeficiency diseases are similar to those that may complicate some autoimmune diseases, particularly connective tissue diseases.
The authors conclude that an increased tendency for malignant changes to occur, rather than a decreased capacity to eliminate malignant cells through immunologic surveillance mechanisms, seems to be the most likely mechanism of oncogenesis in patients with immunodeficiency disease or autoimmune disease; support is presented for this conclusion.
