Kaposi's sarcoma in pregnancy after initiation of highly active antiretroviral therapy: a manifestation of immune reconstitution syndrome

A case of Kaposi's sarcoma (KS) presenting as an immune reconstitution inflammatory syndrome in pregnancy with conservative management is reported. Successful outcomes for mother and baby were achieved. HIV was diagnosed at antenatal booking and highly active antiretroviral therapy commenced at 20 weeks. Multiple lymphadenopathies developed two months later. Excision biopsy of a node confirmed KS. In the absence of advanced disease, she was managed conservatively until delivery. The placenta showed no evidence of KS or human herpes virus 8 (HHV-8). The baby had negative HIV and HHV-8 polymerase chain reaction tests at zero, six and 12 weeks of life. Six months postpartum, the KS had regressed and HHV-8 viral load was undetectable.
