Surgical resection (H&E). a Low power view showed a discrete, well-circumscribed mass with solid component at the periphery with several small central microcysts. (H&E, 2 ×, bar = 3 mm); b high power view of the solid area showing it was composed of intercalated duct cell-type with solid/nested growth patten and scant cytoplasm with clear cell change. c High power view of the apocrine cells in the central area showing the cells had larger nuclei, hyperchromasia, and variable nucleoli, and had abundant eosinophilic cytoplasm and occasional apocrine snouts. (H&E, 40 ×, bar = 50 µm)
