The extent of residual tumor was graded using both the College of Ameri...
BACKGROUND The histologic diagnosis of early mycosis fungoides (MF) and its distinction from inflammatory dermatoses is challenging, owing to the overlap of several features. AIMS 1) To assess the efficacy of histologic criteria to diagnose early MF, 2) to study their utility in differentiating inflammatory mimics of MF.
