Abstract

Objective: To demonstrate the clinical efficacy of topical 5% imiquimod for mycosis fungoides (MF) tumors. Background: Treatment of tumor-stage MF represents a therapeutic challenge because of a limited number of effective topical therapies. Single tumors can be treated with localized radiation but may recur. Systemic therapies are also an option but are associated with serious adverse effects. Imiquimod is a topical agent whose efficacy has been documented in treating MF patches and plaques as well as one case of tumor-stage disease. Methods: We present two stage IIB MF patients, including one with large cell transformation, whose tumors were treated with imiquimod 5% cream after failing prior therapies. Results: The MF tumors in both patients demonstrated a complete response to imiquimod 5% cream without recurrence over 8 years and 2 years of follow-up, respectively. One patient experienced application site irritation and flu-like symptoms as adverse effects. Conclusions: Our case series is only the second report in the literature demonstrating complete resolution of MF tumors with topical imiquimod. An additional therapeutic option for tumor-stage MF, imiquimod may represent an effective alternative to localized radiation for isolated MF tumors and warrants further investigation in the treatment of various stages of MF.
