The presence and distribution of lectin‐binding sites on neoplastic cells of Paget's disease was studied using fluorescein isothiocyanate (FITC)‐conjugated peanut agglutinin (PNA), and FITC‐conjugated wheatgerm agglutinin (WGA), and compared with such lectin‐binding sites on keratinocytes, and cells of eccrine glands, apocrine glands, and mammary glands. Neoplastic cells of both mammary and extramammary Paget's disease showed cytoplasmic staining with both lectins. There were however fewer stained cells in mammary Paget's disease than in extramammary Paget's disease. The cytoplasmic staining of lectin‐binding sites in cells of apocrine glands was in sharp contrast to the cell‐surface staining seen on keratinocytes, or cells of eccrine glands or mammary glands. These results indicate that the lectin‐binding sites of neoplastic cells of Paget's disease more closely resemble those of cells of apocrine glands than of keratinocytes, cells of eccrine glands or cells of mammary glands.
