Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: the patient is a 68-year-old bermudan male who initially presented to on with a complaint of nausea and bloody vomiting for several weeks. in addition, he described an abdominal pain that spread across his abdomen, and which was worse after eating. he denied bright red blood per rectum, melena, diarrhea or constipation, denied any change in his bowel habits. physical examination: vital signs on admission were a temperature of 97.4, pulse 60, respiratory rate 16, blood pressure 75/48, that increased to 93/51 after a 3 liter normal saline bolus, oxygen saturation 98% on room air. laboratory data: on admission, hematocrit 30.9 which was decreased from 40.9 on . he was also hyponatremic, with a sodium of 127, likely due to volume contraction from nausea and vomiting. hospital course: he was admitted to the medical intensive care unit. an esophagogastroduodenoscopy done on showed diffuse friability, erythema and edema, with nodularity and ulceration of the mucosa with contact bleeding in the pre-pyloric region and antrum, with narrowing of the pylorus secondary to edema. these findings were consistent with severe gastritis with ulcerations, and a mass could not be ruled out at that time. the patient was placed on intravenous proton pump inhibitor and made nothing by mouth. repeat endoscopy on showed erosive gastritis with ulcerations as well as an ulcerated bleeding 3 to 4 cm mass of malignant appearance in the distal antrum causing a partial gastric outlet obstruction. biopsy results revealed diffuse large b-cell lymphoma. ct of the abdomen and pelvis with and without contrast revealed circumferential thickening of the gastric antrum, consistent with the patient's stated history of a pre-pyloric mass. extensive lymphadenopathy throughout the abdomen, worrisome for metastatic disease. small bilateral pleural effusions as well as bilateral low attenuation adrenal masses which do not fit with the strict criteria for simple adenomas. however, bone windows showed no suspicious or sclerotic lesions. partial parenteral nutrition was started on . a left brachial vein picc line was placed on , with initiation of total parenteral nutrition. electrocardiogram on showed wandering atrial pacemaker with normal rate, sinus rhythm. bone marrow biopsy was done on , the results of which are still pending. an echocardiogram on showed an ejection fraction greater than 55%, essentially normal left ventricle, normal right ventricle, trivial mitral regurgitation and tricuspid regurgitation, and a small circumferential pericardial effusion. the patient was evaluated by surgery for gastric outlet obstruction. it was felt that the nj tube would be the least invasive, and the fact that the patient may respond to chemotherapy, negating the need for a permanent g or j feeding tube. stenting the gastric outlet obstruction was not an option, as the tumor would be reduced with chemotherapy, freeing the stent and passing it further downstream, where it could not be retrieved and could potentially cause another obstruction. again nj tube was placed on , and the patient was transferred to the oncology service for chemotherapy. on transfer to the oncology service, the patient denied any weakness, malaise, fatigue, dizziness or pain. he denied any headaches, blurry vision, visual changes, throat pain, mouth pain, or trouble swallowing. he also denies chest pain, orthopnea, dyspnea, tachycardia, palpitations, or shortness of breath, or any wheezing or any breathing problems. did report some nausea, relieved with zofran, and history of vomiting previously, but none the day of transfer. he denies any abdominal pain or problems with bowel movements. he denied any melena or bright red blood per rectum. he also reported leg swelling that began in the hospital, and complained of right knee pain and right leg weakness. he denies any leg tenderness or pain. he also denied any dysuria problem with urination. the patient has a past medical history of diabetes, hypertension, coronary artery disease, femoral bruits, peripheral neuropathy, renal insufficiency that has since resolved, as well as gastroesophageal reflux disease. the patient is divorced, with three children, but has not spoken to them in years. he has a brother and a niece who live in and are the designated family contacts, the niece and the brother. he is a former smoker, 50 year history, initially one pack per day, then two packs per day, then three packs per day before he quit five years ago. former weekend alcohol consumer, approximately five to six beers over the weekend. denies any alcohol use now. he has no known drug allergies. his medications at home are aspirin, atenolol, glipizide, lisinopril, metformin, ranitidine. on examination, he had a temperature of 99.2, heart rate of 80, blood pressure of 110/70, breathing at a rate of 20, oxygen saturation 98% on room air. he is a pleasant male, bagged with nj tube taped in place, comfortable, in no acute distress. pupils were equally round and reactive to light, extraocular movements intact, bilateral arcus senilis present. oropharynx is pink, mucous membranes moist. the patient had both upper and lower teeth absent. no ulcers, no thrush, no lesions. the neck was supple, no lymphadenopathy. his rhythm was irregular, pulse in the 80s. soft heart sounds, no murmur. his lungs were clear to auscultation in the upper lobes bilaterally, but decreased breath sounds in bilateral lobes. no crackles, wheezes or rhonchi. he had a cough with some white sputum production. the abdomen was soft, nontender, nondistended, had hyperactive bowel sounds in all four quadrants, mass palpated in the epigastric area, but was nontender to deep palpation. no guarding, no rebound. he had 2+ pitting edema bilaterally, strong bilateral pulses, no cyanosis, cool to touch. he had hose on, with socks on top. his left picc line with tegaderm was intact, clean and dry, no erythema, warmth or tenderness, no signs of infection. the skin was otherwise normal, without lesions. one hypopigmented macule on the right lower quadrant. cranial nerves ii through xii were intact. his laboratories on transfer showed a white count of 8.5, hematocrit of 31.8, platelets of 277. pt 12.8, inr 1.1, ptt 20.8. sodium 137, potassium 4.1, bicarbonate 25, bun and creatinine 16 and .7, glucose 144. calcium 7.5, phos 3.4, magnesium 1.6. ldh 408. on the oncology service, the patient received rituxan on and chop on , and received additional three days of prednisone. his hospital course on the oncology service was significant for hyperglycemia on the prednisone, and total parenteral nutrition, as well as a deep venous thrombosis in the left axillar vein. the patient was started on tube feeds, eventually tolerated the tube feeds well. total parenteral nutrition was discontinued, with some improvement in his serum glucose. he was also started back on his metformin and glipizide. for his deep venous thrombosis, the picc line was removed, and he was started on heparin and coumadin, to be titrated to therapeutic levels. on discharge, the patient was stable, with a hematocrit of 26.3, which had been stable for several days. he was discharged on compazine, protonix intravenously every 12 hours, tylenol as needed, metformin 1000 mg twice a day, glipizide 2.5 mg once daily, as well as coumadin 5 mg once daily. the plan was to discontinue the heparin once the inr was around 2.5, with the heparin therapy in the meantime. we were aiming for a ptt between 50 and 80. the patient is to follow up with dr. and dr. on , , at 12:30 p.m. he is discharged to rehabilitation. , m.d. dictated by: medquist36 procedure: venous catheterization, not
