A 79-year-old man with underlying alcoholic liver cirrhosis presented with complaints of a fever, abdominal pain, and difficulty walking. A diagnostic work-up revealed liver atrophy and chylous ascites, and spontaneous bacterial peritonitis (SBP) was diagnosed based on the cell and neutrophil counts. ⋯ Bcc is often multidrug-resistant and difficult to treat. SBP caused by Bcc has been rarely reported and may have a serious course, thus necessitating caution.

Primary Extragastrointestinal Stromal Tumor of Greater Omentum with Intraperitoneal Bleeding: A Case Report.
Gastrointestinal stromal tumors (GISTs) develop in the digestive tract, mainly in the stomach, small intestine, colon, or esophagus. However, primary tumors with the same pathologic features as GISTs have been reported to occur outside of the digestive tract and are called extragastrointestinal stromal tumor (EGIST). We herein report a rare case of EGIST arising from the greater omentum in a patient with abdominal pain caused by intraperitoneal bleeding from the tumor.

Case Reports
Disseminated Bone Marrow Carcinomatosis Due to Malignant Melanoma of Unknown Primary Origin.
An 80-year-old woman was admitted to our hospital due to appetite loss and vomiting. A blood examination showed liver disorder with disseminated intravascular coagulation. ⋯ A bone marrow biopsy revealed large, atypical cells with brown pigmentation and positive immunostaining for HMB-45, S100 proteins, and CD79a without myeloid or lymphoid markers. We experienced a case of disseminated carcinomatosis of the bone marrow due to malignant melanoma of unknown primary origin.

In hospitalized coronavirus disease 2019 (COVID-19) patients, anticoagulation therapy is administered to prevent thrombosis. However, anticoagulation sometimes causes bleeding complications. ⋯ Although the activated partial prothrombin time was within the optimal range, contrast-enhanced computed tomography (CECT) revealed SMH in the bilateral iliopsoas muscles in both cases, which required emergent transcatheter embolization. Close monitoring of the coagulation system and the early diagnosis of bleeding complications through CECT are needed in severe COVID-19 patients treated with anticoagulants.

Objective Percutaneous patent foramen ovale (PFO) closure is a procedure widely used to prevent recurrence of cryptogenic stroke. Since December 2019, the Amplatzer PFO occluder device has been available in Japan through medical insurance. However, data on the clinical experience with this device are lacking, as it has been approved for use in only a limited number of institutions. ⋯ Almost all cases (92.9%) were performed with a 25-mm device and without significant complications within approximately 1 hour. Conclusion Percutaneous closure using Amplatzer PFO occluder is a safe procedure for Japanese patients. However, further investigations with a larger sample and longer follow-up are needed to confirm this result.
