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: aspirin attending: chief complaint: transfer for possible liver biopsy major surgical or invasive procedure: ultrasound-guided liver biopsy bone marrow biopsy history of present illness: 73 yo man with h/o bph who was in his usual state of health until 6 mos ago when he was diagnosed with ocular pemphigus for which he received immunosuppressives (mtx and prednisone) in addition to ivig. one month ago, he developed fever and cough at home. an outpatient ct scan showed prominence in the head of the pancreas with thickening of the gastric wall and multiple liver lesions concerning for possible abscess. . he was admitted to hosp for further evaluation. per report, his t was 103 at time of admission. his mtx was stopped and prednisone tapered at that time. he was started initially on metronidazole and levaquin for possibility of hepatic abscess. he underwent fna of the liver lesion that revealed definite tumor cells. further typing was not possible given a high degree of necrotic material in the biopsy specimen. tumor markers showed unremarkable afp, cea, and a marginally elevated ca -9. finding were discussed with oncologist who felt that multiple liver lesions and negative afp made liver primary less likely. the patient then underwent ct of the head and chest that showed no definitive primary tumor. bone scan was also negative. mrcp was done that showed no e/o pancreatic mass or ductal dilatation. egd was done that showed friable tissue in the stomach but no e/o carcinoma; biopsies were taken that were negative for malignancy. he was noted to be guiaic positive and required 4u prbcs during his admission. he was transferred to for possible liver biopsy. his prednisone has been discontinued at time of transfer. per d/c summary "consideration at presentation was given to hepatic abscess...there was no aspirate consistent with pus... confirmed that biopsy was negative for abscess." . currently, patient endorses mild abdominal pain radiating around back that is unchanged from prior. he also has mild nausea. he denies bloody or melanotic stools. he had a couple of episodes of vomiting at osh that were non-bilous and non-bloody. he denies shortness of breath, chest pain, headache, lightheadedness or dizziness. past medical history: -recently diagnosed hepatic malignancy of uncertain type -ocular pemphigus -h/o brain aneurysm with bur hole drainage per patient -h/o benign prostatic hypertrophy with biopsy showing no ca -h/o e coli bacteremia following prostate biopsy -neg colonoscopy and neg stool guiaics as recent as 1 month ago social history: patient lives with his wife in . there is no smoking history. he drinks socially. family history: father died of pancreatic cancer at age ?80. mother died at age of natural causes. physical exam: vitals - t: 100.1, bp: 93-100/60-62, hr: 92-100, rr: 20, 02 96%1l per osh records - tm 101.1, bp: 97-110s/50-60s, hr 90-100s general: generally well-appearing, not

radiology: . : renal ultrasound: no hydronephrosis. . : echocardiogram, transthoracic: suboptimal image quality. normal biventricular cavity sizes with preserved global biventricular systolic function. . : ct addomen/pelvis with po and iv contrast: 1. large locally-advanced gastric carcinoma with innumerable hepatic metastases. 2. multiple small cystic-appearing masses throughout the pancreas of probably represent side-branch ipmn. this can be followed with ct at the time of subsequent follow up for his metastatic liver disease. 3. right pleural effusion with adjacent atelectasis. small areas of consolidation cannot be fully excluded. . : lower extremity ultrasound, bilateral: no evidence of dvt in the bilateral lower extremities. . : liver/gallbladder ultrasound: innumerable hyperechoic liver masses which are amenable to ultrasound-guided targeted liver biopsy. . pathology: . : liver biopsy: poorly differentiated carcinoma. . : bone marrow biopsy: markedly hypercellular (80% cellular) erythroid dominant marrow with mild erythroid and megakaryocytic hyperplasia and dysplasia. brief hospital course: 1. metastatic carcinoma of unknown primary: the hematology-oncology and liver services were consulted. the patient underwent ultrasound-guided liver biopsy, which showed poorly differented carcinoma. bone marrow biopsy was performed and was to rule out lymphoma. the hematology-oncology service felt that any tumor-directed therapy would be futile. a family meeting was held, and the patient and his family chose comfort measures only. the patient expired on . . 2. liver failiure: the patient's bilirubin rose rapidly in the setting of extensive liver metastases, rising to 20.1 on . no further lab draws were performed due to the patient's comfort measures only status, but the patient was noted to become increasingly jaundiced. the patient expired on . . 3. palliative care: the palliative care team was consulted. the palliative care team met with the patient and his family and made recommendations to the medical team. the patient received iv morphine (drip and bolus) as needed for dyspnea and abdominal pain. hyoscyomine was used for palliation of oral secretions. . 4. tachypnea: the patient was initially admitted to the medical intensive care unit due to tachypnea and hypotension but was transferred to the floor when the patient and his family chose comfort measures only. the patient's tachypnea and dyspnea were treated with iv morphine on the medical floor. . 5. hypotension: the patient was admitted to the medical intensive care unit due to tachypnea and hypotension. the hypotension was treated with intravenous fluids in the intensive care unit. . 6. ocular pemphigus: this was not an active issue during the patient's admission.
