A. Gross image appeared greyish white to greyish brown nodular tissue. B. Cut section showed solid to cystic area. Microscopic examination revealed tumor tissue predominantly composed of cribriform growth pattern with nest of tumor cells with discrete, rounded punched out gland like spaces filled with eosinophilic to basophilic material (Figure 3A). Area of tubular pattern with multiple ducts and tubules like structure are lined by small uniform cuboidal epithelium (Figure 3B). A focus of solid sheets of tumor cells (<30% solid component) noted. Infiltrating tumor nests are identified within fibrous stroma. Perineural invasion is evident. Focal areas of reactive gliosis with dilated and congested blood vessels are noted.
