Plasmablastic Lymphoma Presenting as Extensive Peritoneal and Retroperitoneal Nodules in an HIV-Positive Patient.

Plasmablastic lymphoma (PBL) is a rare but aggressive subtype of diffuse large B-cell lymphoma (DLBCL). The diagnosis of PBL is challenging as its features overlap with lymphoma and myeloma. The most common presentation involves the oral cavity/jaw in human immunodeficiency virus (HIV)-positive patients. It has also been reported in the gastrointestinal (GI) tract, lymph nodes, and soft tissues. Usually, if PBL involves the GI tract, it presents as a gut tumor mass. In this report, we present an HIV-positive patient with PBL presenting with multiple peritoneal nodules. To our knowledge, this is the first case of PBL presenting as multiple peritoneal and retroperitoneal nodules in an HIV-positive patient. This case emphasizes the rare presentation of a rare malignancy, difficulties in establishing a diagnosis, and the importance of proper and timely management.

Wellens' Syndrome in the Setting of the 2019 Novel Coronavirus (COVID-19).

The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-Cov2), is the causative pathogen of coronavirus disease 2019 (COVID-19), which is primarily described as a respiratory illness. However, a wide array of cardiovascular complications has also been described in the setting of COVID-19. Wellens' syndrome, also regarded as a left anterior descending coronary T-wave syndrome, is an electrocardiography (EKG) pattern that indicates critical proximal left anterior descending (LAD) artery stenosis. It is characterized by deeply inverted T-waves or biphasic T-waves in the anterior precordial chest leads in a patient with unstable angina. Patients typically present with symptoms consistent with acute coronary syndrome. To our knowledge, we present the first case of Wellens' syndrome in a patient with a COVID-19 infection. Furthermore, this case describes stenosis of the left circumflex artery, a variant of the unusual angiographic findings associated with Wellens', as it is usually associated with occlusion of the proximal LAD. The pathophysiology of cardiovascular complications associated with COVID-19 is not well-understood; nevertheless, it was reported that mortality from coronary artery disease (CAD) complications is significantly higher in these patient populations. Healthcare providers should also be aware of identifying Wellens' syndrome, as urgent coronary angiography is superior to stress testing.
