The solid areas were composed of a cellular tumor having round, complex annular tubules of various sizes (arrow) [HE, 100x]. (b) SCTAT having round, complex annular tubules of various sizes and intercommunicating rings around multiple hyaline bodies [HE, 200x]. (c) Multiple hyaline bodies in the center showing strong PAS positivity [PAS, 200x]. (d) Immunohistochemistry showing tumor cells positive for inhibin [immunohistochemistry with DAB as chromogen, 200x].
