Clinicopathological analysis of Paget's disease of the scrotum and penis / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical pathological characteristics, diagnosis and differential diagnosis of Paget's disease of the scrotum and penis.</p><p><b>METHODS</b>Thirteen cases of Paget's disease of the scrotum and penis were analyzed by light microscopy, alcian-blue (AB)/periodic-acid-Schiff (PAS) and immunohistochemical staining.</p><p><b>RESULTS</b>Paget's disease of the scrotum and penis mainly affected old individuals aged 55-84 (mean 71) years. Macroscopically, typical presentations of Paget's disease of the scrotum and penis were eczematoid lesions. Microscopically, Paget cells were distributed singly or in groups (as strands, nests or glandular patterns) within the epidermis. Paget cells were typically stained for AB/PAS, positive for CK7, CEA and EMA, and negative for CK5/6, S-100 and P63. The positive rates of GCDFP-15 and CK20 expressions were 76.92% (10/13)and 53.85% (7/13) respectively.</p><p><b>CONCLUSION</b>Paget's disease of the scrotum and penis is a low-malignancy cutaneous tumor with typical clinical and pathological features. Pathologic diagnosis is based on immunohistochemical findings.</p>
