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: mr. is a 62-year-old male who had known metastatic melanoma. his initial illness began in , where he had a dark line across his right great toenail which widened. he had seen a podiatrist. the lesion was getting bigger and ulcerative. the toenail was removed. he was referred to in and had an amputation of his right toe. in , he had an extensive work-up. a full body ct showed bilateral small pulmonary nodules, and the spleen limber for which mri of the body was recommended, and prominent left pelvic and periaortic lymph nodes were not determined to be pathologic at that time. mri of the whole spine showed diffuse metastatic disease without spinal cord involvement. a bone marrow biopsy on was positive for extensive melanoma involvement. a head ct showed a left frontal metastasis. he was seen by dr. from neuro-oncology at that time. it was recommended that he have surgical removal and be treated with srs in the resection cavity. however, he on developed sudden right-sided weakness and underwent an emergent craniotomy. physical examination: on admission, his vital signs were 98.9, blood pressure 188/102, respirations 20. he was in no acute distress, but uncomfortable. lungs: clear. abdomen: benign. he had no movement in his right side. hospital course: he was taken emergently to the operating room and underwent a left-sided frontal craniotomy. postoperatively, he responded to voice, but was not able to move his right side postoperatively. he had full movement of his left side. he remained in the postanesthesia recovery unit overnight on the evening of for pain control and to check his neurologic signs. a postoperative mri showed postoperative changes in the posterior left frontal lobe with no increased mass effect as compared to his preop study. there was linear enhancement along the anterior aspect of the operative site, and a small amount of residual tumor could not be excluded. there was an area of t1 hyperintensity and susceptibility effect in the operative site which might be related to a small amount of blood products following the surgery. he remained in the icu until for blood pressure control monitoring and due to his dense right hemiparesis and fever to the 102 range. he was more sleepy. he had a chest x-ray and a urine. initially, the urine looked like it was positive for a uti, but the cultures were negative. he did have a chest x-ray that was questionable for pneumonia and was started on levaquin for that. he continued to have high fevers through the . he continued to have full work-up surveillance cultures which showed no source of infection. at that time, we had recommended a meningitis work-up, and mr. refused to have an lp done. four different medical providers, including his oncologist, dr. , spoke with him of the importance of having a work-up for meningitis. on , he had complained of excruciating back pain which was not relieved with dilaudid, percent and his ms contin. a pain service consultation was obtained, which they recommended placing him on a pca overnight to get his pain under control, and then he was started on morphine sulfate ir 15-30 mg q.3-4h. p.o. p.r.n., and morphine sulfate sr 30 mg q. 8h., tylenol 500 mg q.4h., and within 2 days his pain was much better under control. his dilantin was stopped, thinking that may have related his fevers, and he was started on keppra. he continued to have fevers, though they lessened to 101 for the 25 through the 28. he remained neurologically stable, awake, alert, oriented x3, moving his left side spontaneously with minimal to no movement in his right side, tolerating a regular diet, and his pain was much more controlled on his morphine sulfate sr, and his morphine sulfate ir, and it was felt that he could benefit from spinal radiation therapy. for that reason, he is being transferred to the hematology/oncology service of dr. service to have radiation to his back. on the morning of transfer, his hematocrit was 26, and they recommended 2 units of blood. however, before he left he was unable to be typed and screened due to his appointment for radiation oncology. his neurosurgery follow-up should be in the brain tumor clinic in the next 3 weeks. he should be kept on decadron 2 mg p.o. q.12h. and keppra 500 mg p.o. b.i.d. his staples have been removed, and his incision is dry and intact without signs of infection. the patient is being transferred to the hematology/oncology service. , dictated by: medquist36 d: 08:49:23 t: 10:02:24 job#: procedure: other operations on
