Incidence of Morphea following Adjuvant Irradiation of the Breast in 2,268 Patients

Abstract

In the case studies reported to date, morphea is described as a very rare complication. In contrast, our data suggest a cumulative incidence of 1:378, which is higher than other authors have estimated. This leads us to suspect that in a large number of patients, morphea is incorrectly diagnosed as an infection (in the early stages) and radiation-induced fibrosis (in later stages).
