Interstitial Mycosis Fungoides with Systemic Sclerosis-Like Features: A Case Report

Introduction Mycosis fungoides (MF) is the most common form of cutaneous lymphoma,accounting for almost 50% of all types.1 MF occasionally manifests as the interstitial lymphocytic infiltrate that mimics inflammatory morphea,interstitial granulomatous dermatitis,and interstitial granuloma annulare,and this rare histopathological variant has been termed interstitial mycosis fungoides (IMF).IMF can be considered as a transient histopathological pattern in conventional MF,with common clinical presentation as patches and plaques.
