Lymphadenopathic Kaposi's sarcoma in a pediatric patient with acquired immune deficiency syndrome

Area of Science:

• Pediatric Oncology
• Infectious Diseases
• Immunology

Background:

• Acquired immune deficiency syndrome (AIDS) in children presents unique challenges, including varied opportunistic infections.
• Kaposi's sarcoma (KS) is an AIDS-defining illness, but its presentation in pediatric populations is infrequently documented.
• Maternal HIV transmission is a significant route of pediatric infection, even with asymptomatic parents.

Observation:

• Autopsy revealed disseminated lymphadenopathic Kaposi's sarcoma in a six-year-old Hispanic female with AIDS and multiple opportunistic infections.
• The child was presumed to have acquired HIV through maternal transmission, despite both parents being asymptomatic but HIV-antibody positive.
• Unlike typical adult presentations, the child did not exhibit aggressive cutaneous lesions characteristic of AIDS-associated Kaposi's sarcoma.

Findings:

• Disseminated lymphadenopathic Kaposi's sarcoma is an exceptionally rare finding in pediatric acquired immune deficiency syndrome.
• Pediatric Kaposi's sarcoma may manifest with internal lymph node involvement rather than the classic skin lesions seen in adults.
• HIV infection in children can lead to diverse and less common opportunistic conditions.

Implications:

• This case underscores the importance of considering varied presentations of Kaposi's sarcoma in immunocompromised children.
• Enhanced diagnostic vigilance is crucial for identifying rare opportunistic infections in pediatric AIDS cases.
• Understanding atypical KS presentations in children can improve diagnostic accuracy and patient management strategies.
