Papillary eccrine adenoma

摘要：

HistopathologyPapillary eccrine adenoma (PEA),which is a wellcircumscribed,dermal,unencapsulated tumor,generally consists of multiple dilated duct-like structures without apparent continuity with the epidermis (shown in Figure 1).The lining of the ducts is constituted by a double layer of cuboidal,flattened or columnar cells.The inner layer often forms intraluminal papillary projections into the lumen,and there is no decapitation secretion found.Most of the ductal cell nuclei are regular,are oval or round,and contain small nucleoli.And mitoses are rare or absent.The epithelial cells may display clear cell change or squamous differentiation.Some of the lumina were filled by granular or amorphous eosinophilic material (shown in Figure 2 and 3).The surrounding stroma shows an arrangement of collagen bundles around ducts with a sparse lymphohistiocytic infiltrate.
