[Myelodysplastic syndrome with refractory hemorrhage due to reduced platelet aggregation activity].

A 75-year-old woman suffered a cat bite 10 months after myelodysplastic syndrome (MDS) diagnosis. She visited our hospital because the internal bleeding of the wound did not improve. Although the wound was treated, the bleeding did not stop. She was hospitalized for emergency medical treatment because the bleeding volume exceeded 200 ml. Although her platelet count was normal, the platelet function test showed a decrease in collagen and arachidonic acid aggregation. After platelet transfusion, her bleeding stopped. Patients with MDS may potentially have platelet dysfunction. In the case of bleeding without thrombocytopenia, a platelet function test should be performed and treatment intervention, such as platelet transfusion, should be considered.

Peripheral T-cell lymphoma, not otherwise specified: a retrospective single-center analysis.

We retrospectively analyzed clinical and pathological features, treatments, and prognoses in 28 patients with newly diagnosed peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) in Niigata University Medical and Dental Hospital. Of them, 16 were males and 12 were females, and their median age was 62.5 (range, 26-88) years. The International Prognostic Index was high-intermediate/high in 68% of patients. Twelve patients were treated with CHOP/THP-COP and nine with third-generation chemotherapy regimens. At a median follow-up period of 30 (range: 1-164) months, the 2-year overall survival and progression-free survival rates were 61% and 44%, respectively. Further investigation of novel agents for treating PTCL-NOS is warranted.

Early diagnosis of hepatic intravascular lymphoma: a case report and literature review.

Hepatic intravascular large B-cell lymphoma (IVL) is a rare disease entity that involves invasion into various organs. Due to the aggressive behavior and poor prognosis of the disease and the difficulty in making an early diagnosis, some cases are diagnosed at autopsy. Early suspicion and the use of imaging studies and liver biopsies are key for diagnosing IVL; however, no reports have described the results of imaging studies due to the limited number of cases. We herein report the results of imaging studies of hepatic IVL, including the findings PET-CT, dynamic-CT, EOB-MRI and CEUS. These results may help physicians to make an early diagnosis and improve the prognosis.

Advanced gastric cancer and a concomitant pregnancy associated with disseminated intravascular coagulation.

Gastric cancer associated with pregnancy is extremely rare and the prognosis is generally grave. A 31-year-old Japanese women, 41 weeks pregnant, displayed disseminated intravascular coagulation (DIC), although clinical symptoms and diagnostic examinations did not indicate an obstetrical cause. She went into labor spontaneously and vaginally delivered a 3248-g normal female infant, after receiving a blood transfusion. On the day 5 postpartum, a gastroduodenal fiberscope examination indicated advanced gastric cancer. She was also diagnosed with bilateral chronic subdural hematoma and underwent an operation to allow drainage. It was not possible to treat her curatively, so she was treated conservatively for DIC. She died on day 13 postpartum. Necropsy of the iliac bone indicated bone marrow metastasis of adenocarcinoma. This is the first known case of a pregnant woman with DIC occurring as the first manifestation of advanced gastric cancer.
