Microscopic findings. a) At the low power field, the tumor was found to be well-circumscribed. Leaf-like growth pattern was clearly depicted. b) The overlying skin and skin appendage of this tumor showed no remarkable change. c) The epithelium was composed of double layers. The stroma showed low cellularity. d) However, there is other area of tumor which shows increased stromal cellularity in low-to-intermediate degree. e) At high power field, stormal hypercellularity and cell atypism were identified. f) At peripheral, gynecomastoid hyperplasia featuring proliferation of both ductal and stromal cells was found.
