Skin Scoring for Mycosis Fungoides and Sézary Syndrome

Abstract

Assessing skin surface area is essential to determine the skin tumor burden in mycosis fungoides and Sézary syndrome as well as treatment responses. Mycosis fungoides typically presents with patches and plaques with progression to tumors and erythroderma in advanced disease. Quantifying skin involvement requires both assessment of body surface area involved and lesion type (patch, plaque, or tumor). The severity-weighted assessment tool (SWAT) was designed for this purpose in 2002, and a modified SWAT (mSWAT) is now the method of choice for assessing skin tumor burden in both mycosis fungoides and Sézary syndrome.
