Kaposi sarcoma in children with HIV: a clinical series from Red Cross Children's Hospital.

AIM: The study aimed to assess the clinical presentation, diagnosis, and treatment of Kaposi sarcoma in our HIV-positive paediatric population; analyse the increase in Kaposi sarcoma with the HIV epidemic; and look at unique surgical presentations and their implications for gastrointestinal surveillance. The incidence of Kaposi sarcoma, a herpesvirus 8-associated neoplasm of endothelial cells, has increased with the onset of the HIV epidemic. Surgical interest was prompted by a case of Kaposi sarcoma presenting with intussusception.

METHODS

All HIV-positive children with Kaposi sarcoma from 2003 to 2007 were included in the study. A retrospective analysis of clinical data was performed.

MAIN

RESULTS

There were 9 children who ranged in age from 1 to 10 years (median, 7.1 years). Clinical presentations included oropalatal and laryngeal disease (5), pleural effusion (2), inguinoscrotal and skin disease (4), lymph node involvement (3), and gastrointestinal disease with haemorrhage (2), including one as a result of intussusception. Most patients presented with more than one clinical area involved. CD4 counts ranged from 14 to 2105. Two patients developed Kaposi sarcoma on antiretroviral treatment (ART); the remaining patients were started on antiretroviral treatment at presentation. Two patients died from overwhelming disseminated disease and one patient was lost to follow-up. Chemotherapy was required to achieve remission in the remaining 6. Before the HIV epidemic, this hospital treated one patient with Kaposi sarcoma every 4 years; the incidence has now increased to 2 patients per year.

CONCLUSION

Kaposi sarcoma is an increasingly important paediatric cancer in the era of the HIV epidemic. The clinical presentation in children is commonly oropalatal and inguinoscrotal disease. Gastrointestinal involvement was highlighted by a presentation with intussusception. The surgeon's role in diagnosis and management includes clinical recognition, biopsy, and definitive treatment.
