Langerhans cell histiocytosis (LCH) often has a recurrent and refractory course despite multiagent treatment modalities. Common relapse treatments include intense or prolonged cytotoxic chemotherapy regimens. There are a few prior reports that the nonsteroidal anti-inflammatory drug indomethacin demonstrated activity against bone LCH. Here we report indomethacin as a successful treatment for a case of chronic skin LCH that failed multiple prior chemotherapy regimens. This experience supports the need for trials to investigate indomethacin as a treatment for LCH both in the relapsed or refractory setting as well as potential combination or maintenance therapy in newly diagnosed patients.
