Abstract
Background

Few studies support treating morphea (localized scleroderma) with hydroxychloroquine.

Objective

To assess the efficacy of hydroxychloroquine treatment of morphea.

Methods

We conducted a retrospective study of 84 patients who had morphea and were treated with hydroxychloroquine monotherapy for at least 6 months at our institution from 1996 through 2013. The median times to initial and maximal responses were assessed.

Results

Of the 84 patients (median age at diagnosis, 29.5 years), 65 (77.4%) were female, 36 (42.9%) had a complete response to hydroxychloroquine, 32 (38.1%) had a partial response greater than 50%, 10 (11.9%) had a partial response less than or equal to 50%, and 6 (7.1%) had no response. The median time to initial response was 4 months, and the median time to maximal response was 12 months. Ten patients (11.9%) experienced adverse effects from hydroxychloroquine; the most common adverse effect was nausea (6 patients).

Limitations

Retrospective study.

Conclusions

Hydroxychloroquine is a valuable treatment for morphea because of its high response rate and low rate of adverse effects; however, prospective studies are needed to determine its true efficacy.
