Kaposi sarcoma (KS), an opportunistic neoplasm linked to human herpes virus type 8, presents uniquely in children with HIV. Histopathology is crucial for diagnosing childhood KS, even with few lesions, and necessitates HIV testing.

Area of Science:

  • Oncology
  • Virology
  • Immunology

Background:

  • Kaposi sarcoma (KS) is an opportunistic neoplasm associated with human herpes virus type 8 (HHV-8).
  • KS presents in four forms: classical, endemic (AIDS-associated), epidemic, and iatrogenic.
  • While histopathologically similar, KS forms differ in prognosis and treatment.

Observation:

  • A rare case of Kaposi sarcoma in a child with HIV infection is presented.
  • The patient exhibited only two cutaneous lesions: one giant tumor and one nodular lesion.
  • The child's HIV infection occurred in childhood, with risk factors other than homosexuality.

Findings:

  • Histopathologic examination confirmed Kaposi sarcoma in the child's lesions.
  • The case highlights KS presentation in pediatric HIV, with atypical lesion morphology.

  • The study underscores the association between KS and HHV-8, even in immunocompromised children.

    • Implications:

    • Emphasizes the importance of histopathologic diagnosis for any angiomatous tumor in children, especially for solitary KS lesions.
    • Highlights the critical need to investigate for concurrent HIV infection in pediatric KS cases.
    • Suggests considering KS in the differential diagnosis of childhood skin lesions, particularly in the context of HIV risk factors.
