Kaposi Sarcoma Associated with Tofacitinib Use in a Patient with Rheumatoid Arthritis

Abstract

Kaposi sarcoma is a rare vascular malignancy associated with HHV-8 infection. Four variants of Kaposi sarcoma have been described: Classic, African, HIV-associated, and iatrogenic. Iatrogenic Kaposi sarcoma is typically associated with immunosuppression and organ transplantation.

We present a case of iatrogenic Kaposi sarcoma associated with tofacitinib therapy.

A 69-year-old woman with rheumatoid arthritis receiving tofacitinib presented with multiple firm, purple-red nodules and brown plaques on the left lower extremity and a single lesion on the right medial calf. Clinicopathologic correlation confirmed a diagnosis of Kaposi sarcoma.

Tofacitinib was discontinued and she was started on Alitretinoin 0.1% gel bid. The purple-red Kaposi sarcoma nodules decreased 50% in size after 4 months and resolved at 1 year off the tofacitinib and initiation of alitretinoin gel.

As the use of immunomodulators and biologics continues to expand, awareness of this association is important for prompt diagnosis and management.
