BULLOUS MORPHEA - A DISTINCT ENTITY

A 57-year-old woman who had undergone lumpectomy for infiltrating duct-cell carcinoma of the right breast was found to have morphea after receiving radiation therapy. Three years later she developed a vesicular eruption on the area of the morphea, which was diagnosed as bullous morphea. The histologic findings of the vesicular component were characteristic of lichen sclerosus et atrophicus. It is suggested that in some cases bullous morphea represents a secondary appearance of bullous lichen sclerosus et atrophicus on a lesion of morphea.
