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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: thrombocytopenia major surgical or invasive procedure: bone marrow biopsy history of present illness: this is a 53 year-old male with a history of presumptive crohn's ileitis who presents with thrombocytopenia and anemia. he carries a presumptive diagnosis of inflammatory bowel disease since when he presented to hospital in new with small bowel obstruction, and abdominal ct demonstrated "...ileocecal valve appears abnormal. findings are of concern for crohn's disease... a soft-tissue mass is seen in the right pelvis, this measures 4cm x 3.8cm." colonoscopy was done on and showed nodularity of terminal ileum more pronounced than usual. biopsy from terminal ileum was normal, and rectal biopsy showed reactive lymphoid aggregates. he was then started on mesalamine(asacol) but had difficulty tolerating it due to diarrhea. on , he was started on prednisone 60mg, and was subsequently tapered to 40mg daily prior to admission. he was seen on by dr. in the gi department for further evaluation. at that time he complained of fatigue and dyspnoea and continued to have abdominal distention. blood work was drawn and returned showing hct of 22 and platelets of 20. he was instructed to discontinue mesalamine (as a possible cause of thrombocytopenia) and to report to the emergency room. at hospital ed, he was confirmed to have platelets of 13 and hct of 21 on . he was transferred to for further evaluation, upon recommendation by the pcp. . presently, the patient reports weight loss from 245 lbs. to 212 lbs. over the past one month. he continues to report marked fatigue and exertional dyspnoea. he has not had a bowel movement in the past 3 days. patient reports his appetite is less than usual, although he did eat dinner last night. he reports that when he has bowel movements, defecation is painful, but he denies tenesmus. also, the bowel movements are initially well-formed, but each bowel movement is followed by some loose stool. no blood or mucus in stools. patient endorses nausea, but no vomitting. he denies fevers, vision changes, rashes, or joint symptoms. n, or focal weakness. . laboratories: from hospital: : anca <1:20 (<1:20) no c- or p-anca by ifa <7.5 (<7.5) endomysial iga <1:10 (<1:10) ttg iga <4.0 (<4.0) gliadin igg <10.0 (<10.0)

1. large soft tissue mass involving a distal ileal loop. differential diagnosis includes lymphoma, carcinoid (although there is no significant desmoplastic reaction or calcification) or primary small bowel adenocarcinoma. 2. extensive omental infiltration. 3. marked mesenteric and retroperitoneal lymphadenopathy. 4. ascites. 5. focal liver lesion in right lobe, which may represent metastasis. specimen: bone marrow aspirate and core biopsy: diagnosis: extensive involvement by malignant b-cell non-hodgkin lymphoma, high-grade, see note. interphase fish analysis, 100-300 cells nuc ish(mycx2)(5'myc 'mycx1) fish evaluation for a myc rearrangement was performed on nuclei with the lsi myc dual color, break apart rearrangement probe ( molecular) at 8q24 and is interpreted as abnormal. rearrangement was observed in 93/100 nuclei, which exceeds the range of a normal hybridization pattern (up to 4% rearrangement) established for this probe in our laboratory. a myc rearrangement is found in more than 90% of burkitt lymphomas, but can also be found occasionally in other histologies of non-hodgkin's lymphoma. the myc rearrangements in burkitt lymphomas result in myc overexpression, generally by juxtaposition with an immunoglobulin gene. peritoneal fluid diagnosis: positive for malignant cells, consistent with lymphoma. highly atypical medium to large-sized lymphocytes, consistent with lymphoma. brief hospital course: the patient is a 53-year-old gentleman who presented being treated at osh with steroids for several weeks for diagnosis of crohn's disease. he was transferred to after presenting to the ed of osh with sob and anemia, low platelets and increasing abdominal girth. he was admitted to the oncology service at and the patient was found to have pancytopenia. following admission, a bone marrow biopsy was done on and which ultimately showed cells consistent with non-hodgkin's lymphoma. the patient was treated for tumor lysis syndrome in preparation for chemotherapy. he had a paracentesis done on to remove fluid to help with respiratory distress from restriction in the setting of abdominal distention. cells from the ascitic fluid also were sent for evaluation and were found to be positive for malignant cells and consistent with lymphoma. a diagnosis of burkitt's lymphoma was made based on the available clinical evidence and the findings on diagnostic testing conducted. he was treated with high dose steroids. the morning following the paracentesis () the patient deveolped worsening abdominal distention and pain and respiratory distress. surgical evaluation was requested and patient was moved to the micu ( icu) for further care where he was intubated and broad spectrum antibiotics were given given concern for evolving sepsis. ct scan showed peritoneal carcinomatosis and bowel dilitation but no evidence of free air. surgical consultation concluded that no surgical intervention was indicated. the patient had central venous catheter, femoral dialysis catheter and arterial catheter placed to allow administration of chemotherapy and management of hypotension and worsening renal failure and hyperkalemia expected to worsen with tumor lysis. chemotherapy was initiated and broad spectrum antibiotics were continued. during his icu course he subsequently and rapidly developed sepsis with refractory hypotension, abdominal compartment syndrome and acute renal failure despite all interventions. the patient was placed on cvvh to allow management of volume and elecrolyte abnormalities. in the setting of rapid expansion of abdominal distention and worsening elevations in intra-abdominal pressures bedside u/s and x-ray of the abdomen was performed and continued to show minimal ascites and no evidence of free air. the patient's bladder pressure was approx 40. the patient was placed on cyclophosphamide to treat the lymphoma. the patient developed worsening sepsis requiring pressor support and aggressive ivf resuscitation. cultures eventually did return with clostridium perferingens. he subsequently required 4 pressors to support his bp. the patient was unable to maintain his cardiac output and he was give nitrogen mustard and a second dose of cyclophosphamide emergently in hopes of reducing his tumor burden. the patient developed hepatic ischemia, bowel ischemia, and complete renal failure secondary to his compartment syndrome and sepis. the patient was given large amounts of bicarb to attempt to counteract his acidemia in addition to the cvvh. the patient subsequently passed away despite aggressive intervention with his family and dr. at the bedside on . medications on admission: prednisone 40 mg po daily discharge medications: none discharge disposition: expired
