AI Article Synopsis

  • A rare case of a 5-year-old boy from a Bantu background is reported, presenting with oral-visceral Kaposi sarcoma after treatment for high-risk acute lymphoblastic leukemia, marking possibly just the second documented case of this phenomenon.
  • The boy developed a non-painful oral mass one month post-treatment, which was successfully treated with a regimen of bleomycin and vincristine, demonstrating a positive clinical response.
  • The report emphasizes the need for heightened awareness among clinicians regarding the potential for second malignancies like Kaposi sarcoma in children who have undergone leukemia treatment, recommending routine evaluations during long-term follow-ups.

Article Abstract

Background: There have hardly been any reported cases of children presenting with Kaposi sarcoma as a second malignancy following treatment for acute lymphoblastic leukemia outside a transplant setting.

Case Presentation: We report a case of a 5-year-old boy of Bantu origin, which, to our knowledge, could be only the second reported case of oral-visceral Kaposi sarcoma after acute lymphoblastic leukemia treatment. The patient presented with a 1-month history of progressive, non-painful, soft tissue oral mass, 1 month after completing treatment for high-risk acute lymphoblastic leukemia. He was successfully treated for Kaposi sarcoma on a two-drug regimen (bleomycin and vincristine) with good clinical response.

Conclusion: Visceral Kaposi sarcoma as a second malignancy may occur after pediatric acute lymphoblastic leukemia treatment, but its rarity makes it unlikely to raise suspicion among clinicians, thus precluding early diagnosis and treatment. We recommend routine evaluation for Kaposi sarcoma lesions in children undergoing long-term surveillance following treatment for childhood acute leukemia.

Kaposi's sarcoma-associated herpesvirus (KSHV) is a human gammaherpesvirus associated with Kaposi's sarcoma and B cell malignancies. Like all herpesviruses, KSHV contains conserved envelope glycoproteins (gps) involved in virus binding, entry, assembly, and release from infected cells, which are also targets of the immune response. Due to the lack of a reproducible animal model of KSHV infection, the precise functions of the KSHV gps during infection are not completely known.

Modulation of Lymphotoxin β Surface Expression by Kaposi's Sarcoma-Associated Herpesvirus K3 Through Glycosylation Interference.

J Med Virol

Department of Infection Biology, Global Center for Pathogen and Human Health Research, Lerner Research Institute, Cleveland Clinic, Cleveland, Ohio, USA.

Kaposi's sarcoma-associated herpesvirus (KSHV) employs diverse mechanisms to subvert host immune responses, contributing to its infection and pathogenicity. As an immune evasion strategy, KSHV encodes the Membrane-Associated RING-CH (MARCH)-family E3 ligases, K3, and K5, which target and remove several immune regulators from the cell surface. In this study, we investigate the impact of K3 and K5 on lymphotoxin receptor (LTβR) ligands, LTβ and LIGHT, which are type II transmembrane proteins and function as pivotal immune mediators during virus infection.

ALA photodynamic therapy combined with dual 980nm/1470nm diode laser for classic Kaposi's sarcoma.

Photodiagnosis Photodyn Ther

Institute of Photomedicine, Shanghai Skin Disease Hospital, Tongji University School of Medicine, Shanghai, China. Electronic address:

A 84-year old man who has a history of refractory Kaposi's sarcoma (KS) was treated with ALA-PDT combined with the dual 980-nm/1470-nm diode laser for 6 times every other week. Satisfactory result was noted without any unbearable adverse effects. The combination of the dual 980nm/1470nm diode laser and ALA-PDT may be an ideal strategy in treating local KS with good tolerance, especially in elder patients who can not tolerate radiotherapy and chemotherapy.

KSHV hijacks the antiviral kinase IKKε to initiate lytic replication.

PLoS Pathog

January 2025

Institute of Pediatric Infection, Immunity, and Critical Care Medicine, Shanghai Children's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

IKKε is a traditional antiviral kinase known for positively regulating the production of type I interferon (IFN) and the expression of IFN-stimulated genes (ISGs) during various virus infections. However, through an inhibitor screen targeting cellular kinases, we found that IKKε plays a crucial role in the lytic replication of Kaposi's sarcoma-associated herpesvirus (KSHV). Mechanistically, during KSHV lytic replication, IKKε undergoes significant SUMOylation at both Lys321 and Lys549 by the viral SUMO E3 ligase ORF45.
