Disseminated Intravascular Coagulation as an Initial Manifestation of Metastatic Prostate Cancer Emergently Treated with Docetaxel-Based Chemotherapy.

A 70-year-old male presented with hematuria and bruising of arms and legs for the last three days. He also complained of urinary frequency and hesitancy and weight loss of 40 pounds over a span of four months. Initial blood tests showed prothrombin time (PT) of 25.1 seconds, international normalized ratio (INR) of 2.5, partial thromboplastin time (PTT) of 43.9 seconds, fibrinogen of 60 mg/dl, fibrin degradation products (FDP) of more than 20 µg/ml, and platelets of 88,000/µl. The impression was disseminated intravascular coagulation (DIC). A search was initiated to determine the underlying etiology precipitating DIC. Due to urinary symptoms and weight loss, prostate-specific antigen (PSA) was ordered. PSA was elevated at 942 µg/dl. Computed tomography (CT) of the abdomen and pelvis without contrast showed an enlarged prostate with mass effect on the bladder base, left-sided hydronephrosis, and numerous enlarged pelvic lymph nodes. A bone scan of the whole body showed increased sclerosis of the L3 vertebral body. There was a concern for metastatic prostate cancer precipitating DIC. On first admission, our patient's DIC was stabilized with FFP and cryoprecipitate transfusions. He refused chemotherapy, and degarelix was not economically feasible. Accordingly, he was started on androgen deprivation therapy (ADT), bicalutamide, and leuprolide as an inpatient, pending the tissue biopsy. The patient refused a prostate biopsy. A bone marrow biopsy was performed which confirmed metastatic prostate adenocarcinoma. The patient was stable for discharge with a plan for outpatient chemotherapy. Subsequently, he was lost to follow-up with the oncology. Six months after the initial presentation, he was readmitted with hematuria. Repeat PSA worsened to 1,970 µg/dl. Blood work was consistent with acute DIC. He refused chemotherapy again. So, he was restarted on ADT. However, his hematuria and DIC panel were worsening. He was emergently started on docetaxel as an inpatient (after patient agreement). Within three days of starting chemotherapy, his hematuria resolved and DIC panel showed consistent improvement.

Atypical Presentation of Acute Myeloid Leukemia.

We present a case of a 48-year-old male who presented with worsening pleuritic chest pain for 2 h. He also complained of fever, malaise, headache and severe neck pain. Electrocardiogram (ECG) showed ST segment elevation in leads I, II, aVL and V5 with PR elevation and ST depression in aVR. On admission, troponin-I was 14.8 ng/mL. Based on ECG changes, elevated troponin and family history of early coronary artery disease, the patient was emergently taken to cardiac catheterization lab. Angiography showed non-obstructive coronaries, mild hypokinesis of mid inferior and anterolateral wall with ejection fraction (EF) of 40-45%. Based on above presentation and angiography findings, the diagnosis of acute myopericarditis was made. He was started on colchicine and ibuprofen. The other workup to determine etiology of myopericarditis was negative as shown below. Given the history of fever, headache and worsening neck pain, we also became suspicious of meningitis. Lumbar puncture was performed which was negative. On the day of admission, he was found to have blasts on complete blood count and peripheral smear. Bone marrow biopsy and flow cytometry confirmed the diagnosis of acute myeloid leukemia (AML). He received induction and salvage therapy. Repeat bone marrow confirmed complete remission and normal cytogenetics. Although pericardial or myocardial biopsies are unavailable for our patient, in the absence of other causes, it does appear that his acute myopericarditis was associated with AML.

Primary malignant mixed müllerian mesodermal tumor mimicking a rectosigmoid carcinoma: a case report and review of the literature.

We report a case of a 53-year-old female who presented with chronic constipation and abdominal discomfort for six months. Her past surgical history was significant for a total abdominal hysterectomy with bilateral salpingooophorectomy, performed eight years ago, for uterine fibroids and endometriosis. Workup revealed a mass measuring 5 × 4.5 × 2 cm in the rectosigmoid colon. Patient underwent a low anterior resection and a fungating, centrally ulcerated rectosigmoid mass with a positive mesorectal margin was removed. Histopathology revealed a heterologous mixed mesodermal tumor (chondroid and osteoid elements). The epithelial component was compatible with a grade 2 endometrioid adenocarcinoma. Immunohistochemical stains were supportive, with positive expression for CK7 and ER, negative for CK20, and only very focally and weakly positive for both CDX2 and p63. Chromogranin, synaptophysin, and TTF-1 were negative. Following surgery, she was treated with five cycles of carboplatin (AUC 6) and paclitaxel (175 mg/m(2)), followed by irradiation. Twenty-six months later, patient continues to be asymptomatic and disease-free. Mixed müllerian mesodermal tumors mimicking colorectal cancer have been reported in the past. Our case highlights the rarity and the challenges encountered in diagnosing and treating these rare tumors.

Permanent sensorineural deafness in a patient with chronic myelogenous leukemia secondary to intracranial hemorrhage.

A 52-year-old male presented with tinnitus and fullness in left ear for one day. Workup revealed a white blood cell count of 685 × 10(3)/µL with marked increase in granulocyte series and myeloid precursors on peripheral smear. The initial impression was chronic myelogenous leukemia with hyperleukocytosis, and patient was started on hydration, hydroxyurea, and allopurinol. Patient tolerated bone marrow biopsy well but continued to bleed excessively from the biopsy site. Results confirmed Philadelphia chromosome positive chronic myelogenous leukemia (chronic phase). On day three of hospitalization, patient developed sudden slurred speech along with shaking movements involving extremities. Magnetic resonance imaging revealed multiple hemorrhages throughout the brain. Hydroxyurea was continued until insurance coverage for nilotinib was getting approved. On day nine of hospitalization, patient developed sudden bilateral sensorineural deafness. Repeat magnetic resonance imaging revealed multiple new hemorrhages throughout the brain. Computer tomography of the temporal bones showed inflammatory changes in right and left mastoid cells. Nilotinib was started on day eleven of hospitalization. Patient's white blood cell count continued to decrease, but there was no improvement in hearing. Four months later, patient was treated with bilateral transmastoid cochlear implants. This case highlights permanent deafness as a hemorrhagic complication secondary to chronic myelogenous leukemia.

Diagnosing a gastric submucosal tumor using jumbo biopsy "unroofing" technique: a case report and review of the literature.

We report a case of a 40-year-old female who presented with dyspeptic symptoms for six months. Upper GI endoscopy revealed a submucosal nodule in gastric antrum. Using "jumbo biopsy unroofing technique" we were able to get adequate tissue for analysis. Histopathology revealed a type III gastric carcinoid. Patient was treated with laparoscopic distal subtotal gastrectomy with Roux-en-Y reconstruction and partial omentectomy. Although there was no evidence of metastasis on initial presentation, eighteen months later, patient was found to have multiple metastatic lesions in her liver. Patient's lesions were treated with intra-arterial (hepatic artery) Yttrium-90.
