description: "Limited patches, papules, and/or plaques covering less than 10% of the skin surface.  May further stratify into T1a (patch only) vs. T1b (plaque +/- patch).  Note: for skin, patch indicates any size skin lesion without significant elevation or induration.  Presence/absence of hypo- or hyperpigmentation, scale, crusting, and/or poikiloderma should be noted.  Plaque indicates any size skin lesion that is elevated or indurated.  Presence or absence of scale, crusting, and/or poikiloderma should be noted.  Histologic features such as folliculotropism or large-cell transformation (more than 25% large cells), CD30+ or CD30-, and clinical features such as ulceration are important to document.
