We describe a 54-year-old woman who developed right breast morphea aft
er radiotherapy following a lumpectomy for infiltrating lobular carcin
oma. Skin biopsy confirmed the histological features of morphea. Treat
ment was initiated with both topical and intralesional steroid, result
ing in marked improvement. Morphea following radiotherapy is an infreq
uently recognized phenomenon. However, when diagnosed early it may be
effectively managed with local steroid treatment.
