(a) The cysts were lined by endometrial glands and stroma along with numerous hemosiderin laden macrophages (dotted arrow). 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].

On microscopy, the cysts were lined by endometrial glands and stroma along with numerous hemosiderin laden macrophages (Figure 1(a)). No capsular infiltration was noted (Figure 1(b)). The cells were bright magenta pink positive for periodic acid schiff (PAS; Figure 1(c)). Both CD-10 and inhibin showed bright cytoplasmic positivity, thus confirming the diagnosis (Figure 1(d)).
