Tumor-stage mycosis fungoides of the vulva successfully treated with local low-dose radiotherapy.

Mycosis fungoides (MF) is the most common type of primary cutaneous T-cell lymphoma. According to the proposed guidelines for MF, skin-directed therapies are the treatment of choice for patients with limited stage disease. We present a case of early-stage MF, who progressed to tumor-stage MF during the postpartum period, showing a solitary ulcerated tumor on the vulva, which was successfully treated with local response-based, low-dose radiotherapy.
