Precautions When Performing Pericardiocentesis in Patients with Cardiac Tamponade-complicated Malignancy: A Case Report and Review of the Literature.
A 51-year-old woman who had previously undergone left mastectomy for left breast cancer accompanied by multiple metastasis experienced worsening dyspnea. Physical and imaging assessments of the hemodynamics suggested cardiac tamponade, and emergency pericardiocentesis was successfully performed. ⋯ Contrast-enhanced computed tomography with continuous mechanical support demonstrated massive thrombi in both pulmonary arteries. An abrupt decrease in the central venous pressure and an increase in the venous return following pericardiocentesis might result in the migration of a deep venous thrombus and fatal acute pulmonary thromboembolism.

Objective Patients with hematological malignancies and solid organ tumors reportedly tend to have a more severe coronavirus disease 2019 (COVID-19) trajectory than do those with other diseases. We studied the clinical features and outcomes of nosocomial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the seventh wave of the pandemic. Methods This study retrospectively described the characteristics of COVID-19 clusters involving patients in the hematology/respirology ward of Kochi Medical School Hospital during the seventh wave of the pandemic of SARS-CoV-2. ⋯ Cycle threshold values in nasopharyngeal samples were significantly lower in patients with COVID-19 than in those who were asymptomatic at the time of the diagnosis with SARS-CoV-2 infection. All SARS-CoV-2-infected inpatients recovered or did not develop symptoms of COVID-19. Conclusion COVID-19 vaccination, early or preemptive treatment with antivirals, and intrinsic changes in SARS-CoV-2 may have contributed to the more favorable outcomes in our series than in previously reported nosocomial clusters.

A 59-year-old man with a high level of antinuclear antibody received nivolumab and ipilimumab plus chemotherapy for lung cancer. Two weeks after the second course, he was admitted with a fever and severe fatigue. ⋯ However, his cardiac function rapidly worsened, and he died on the fifth day after admission. There is no established treatment strategy for fulminant myocarditis as an irAE, and the further exploration of viable treatment strategies is required.

A 64-year-old man with a history of diabetes and gallstones was admitted to our institution with suspected pancreatic malignancy. Computed tomography (CT) revealed multiple pancreatic cysts and massive ascites, and endoscopic ultrasonography (EUS) revealed a 28×27-mm hypoechoic mass in the pancreatic head. ⋯ The patient was administered 30 mg of prednisolone daily. After 11 days, CT revealed that the pancreatic cysts and ascites had reduced in size.

Case Reports
Diffuse Large B-cell Lymphoma Involving an Abundant Infiltration of T Follicular Helper Cells: A Case Report.
A 76-year-old man presented with skin plaque and splenic nodules, and diffuse large B-cell lymphoma (DLBCL) with infiltration of T-cells was suspected based on the skin lesions. The disease showed indolent clinical behavior for three months, when systemic lymphadenopathy rapidly evolved. ⋯ A polymerase chain reaction-based analysis of immunoglobulin variable heavy chain showed that the skin, splenic nodules, and inguinal lymph node shared the same clone. This case indicates that the dysregulated infiltration of TFH cells in the tumor microenvironment accelerates the lymphomagenesis and progression of DLBCL.
