Grossly, innumerable papillary projections lined the internal surface of the cyst (a). Microscopic papillary frond-like architecture and basophilic mucoid secretions (b; haematoxylin and eosin; original magnification, ×20) were composed of proliferating cuboidal to columnar epithelial cells with eosinophilic cytoplasm and absent nuclear atypia (c; haematoxylin and eosin; original magnification, ×600). Nuclear expression of androgen receptor was seen via immunohistochemistry (d; haematoxylin and eosin; original magnification, ×600).
