We report a case of simultaneous occurrence of Hodgkin's lymphoma and Kaposi's sarcoma within the same lymph nodes of a 61-year-old woman without human immunodeficiency virus (HIV) infection. Epstein-Barr virus (EBV) was detected in the Hodgkin cells and Reed-Sternberg cells by EBV LMP-1 immunostaining and Epstein-Barr virus encoded early RNA (EBER) in situ hybridization. In contrast, Kaposi's sarcoma cells were positive for human herpes virus 8. This case is documented because the occurrence of 2 independent tumors infected by 2 unrelated viruses within the same lymph nodes of a patient without HIV infection has rarely been observed.

In solid organ transplant recipients (SOTRs), the oncogenic virus human herpesvirus-8 (HHV-8) also named Kaposi sarcoma herpesvirus (KSHV) causes four clinical diseases: Kaposi Sarcoma, Primary Effusion Lymphoma, Multicentric Castleman Disease (MCD), and KSHV inflammatory cytokine syndrome (KICS). This review outlines these clinical scenarios and discusses their management. Although HHV8 related disease in SOTR was first described more than three decades ago, there is a lack of data on treatment so much of the guidance is based on evidence in other immunodeficient patients, particularly people living with HIV.

Background: Uncontrolled hypertension is the leading modifiable risk factor for cardiovascular disease mortality and remains high in low-middle income countries like Haiti. Barriers and facilitators to achieving hypertension control in urban Haiti remain poorly understood. Elucidating these factors could lead to development of successful interventions.

The clinical management of people with multidrug-resistant (MDR) human immunodeficiency virus (HIV) remains challenging despite continued development of antiretroviral agents. A 58-year-old male individual with MDR HIV and Kaposi sarcoma (KS) was treated with a new antiretroviral regimen consisting of anti-CD4 domain 1 antibody UB-421 and capsid inhibitor lenacapavir. The individual experienced delayed but sustained suppression of plasma viremia and a substantial increase in the CD4 T cell count.

Kaposi's sarcoma (KS) is a tumor involving blood vessels and lymphatic tissue. It is caused by human herpes virus-8, typically in HIV infection in individuals with AIDS. There are 4 major types of KS including classic, endemic, immunosuppression, and AIDS-related.

Vascular anomalies are broadly classified into 2 categories: vascular tumors and vascular malformations. Vascular anomalies frequently present as cutaneous lesions in infants. This review summarizes vascular anomalies that most commonly present as dermatologic lesions in the neonatal period, with a focus on the clinical findings, pathophysiology and histology, relevant radiographic findings, and management of common vascular anomalies such as infantile hemangiomas, congenital hemangiomas, and Kaposiform hemangioendothelioma, along with vascular malformations, including capillary, lymphatic, venous, and arteriovenous malformations.
