case_images: (a) Microscopic analysis displaying tumor proliferation exhibiting a microcystic architecture arranged on a sparse fibrous stroma, (b) papillary architecture observed in certain areas of the tumor proliferation, (c) presence of a mucinous component within the tumor, and (d) histological evaluation depicting medium-sized polygonal cells with vacuolated, granular, and eosinophilic cytoplasm. Minimal pleomorphism and low mitotic activity are observed.
