Eosinophils in Mycosis Fungoides: An Uncommon Finding in the Patch and Plaque Stages
The American Journal of Dermatopathology, 07/27/2012
Dalton S et al. – The data indicate that eosinophils are uncommon in cases of patch and plaque mycosis fungoides (MF). When a pathologist is faced with evaluating a biopsy that lacks some of the criteria used to make the diagnosis of patch stage MF, yet demonstrates >3 eosinophils per tissue section, dermatitis is the likely diagnosis. However, in cases where fewer than 3 eosinophils are present in sections, patch stage MF cannot be excluded.
