case_images: Microscopically, the ovarian cyst was lined by stratified squamous epithelium associated with keratinous material, hair follicles, and sebaceous glands (Figure 1).
case_images: Adenomatoid tumor. (a) shows well circumscribed tumor with few peripheral lymphoid aggregates (H&E x4). (b) shows major pattern of adenoid and glandular cells with markedly vacuolated cytoplasm (H&E x20).

case_images: The solid nodule showed an unencapsulated but circumscribed tumor with several lymphoid aggregates noted towards the periphery of the tumor (Figure 2(a)). Some tumor cells exhibited marked vacuolation (Figure 2(b)).
case_images: Positive immunoreactivity to calretinin (H&E x20). Adenomatoid tumor with cells displaying strong and diffuse positivity for calretinin-index of mesothelial origin.

case_images: The circumscribed solid tumor was strongly positive for pancytokeratin (AE1/AE3), calretinin (Figure 3), and D2-40, weakly positive for WT1, and negative for CD31.
