ADAMANTINOMA

Adamantinoma: Nests of basaloid epithelial cells with peripheral palisading, in the fibrous stroma. Few nests show spindle shaped epithelial cells with plump nuclei (H&E,X100)

Adamantinoma: Nests and sheets of spindle shaped epithelial cells with peripheral palisading surrounded by fibrous stroma (H&E,X100)

Adamantinoma: Nests and sheets of spindle shaped epithelial cells with peripheral palisading surrounded by fibrous and hyalinized stroma (H&E,X100)

Adamantinoma: Nests and sheets of spindle shaped epithelial cells with peripheral palisading surrounded by fibrous and hyalinized stroma (H&E,X400)

Adamantinoma: Nests of basaloid epithelial cells and spindle shaped cells showing vague peripheral palisading pattern, surrounded by fibrous stroma. Squamoid differentiation of epithelial cells are seen (H&E,X400)

Adamantinoma: Sheets of spindle shaped epithelial cells showing squamoid differentiation with cells having abundant eosinophilic cytoplasm. These sheets of cells show vague peripheral palisading pattern. Interstitial fibrous stroma is present (H&E,X100)
