a) The cyst wall was lined by luminal epithelium with occasional apocrine snouts and basal myoepthelial cells, sitting on the collagenous capsule. b) Papillary projection of columnar cells with apocrine feature was observed (insert). c) The intracystic polypoid projection consisted of proliferation of glandular structures embedded in collagenous stroma. d) The tubules were lined by luminal columnar cells with apocrine secretion and by basal myoepithelial cells.
