Quality of life/ Life expectancy If the lesions are mild, the patient will be subject to a good deal of pain. If the lesions are severe, the overall quality of life is devastating. The impaired skin barrier function commonly leads to localized infection, which sepsis and death may follow. The pain from the oral and pharyngeal ulcers interfere with eating, which can compromise nutritional health. The general prognosis for<unk>  is poor. It is more hopeful if the tumor is benign, but in the case of malignant tumors, the mortality rate is roughly 90%. The two most commonly associated types of tumors are non-Hodgkin lymphoma and chronic lymphocytic lymphoma; nearly all of these patients die within two years of diagnosis. This is attributed to the effects of the tumor combined with the negative side effects of the medication administered to treat<unk> . Roughly 1/3 of the deaths from<unk>  stem from pulmonary insufficiency which is brought about by the action of<unk>  on the respiratory mucosa. It manifests as dyspnea and progresses to bronchiolitis obliterans (non-reversible obstructive lung disease) via an unknown mechanism. Risk Factors As<unk>  is ultimately caused by the presence of a tumor, it is not contagious. There is no known way to predict who will become afflicted with it. Patients with cancer are therefore a group at risk. Although<unk>  has been known to affect all age groups, it is more likely to afflict middle-aged to older patients.
