Which of the following is not a histological feature of adamantinomatous craniopharyngioma?
Adamantinomatous craniopharyngioma Consists of nests or cords of stratified squamous epithelium embedded in a spongy reticulum" that becomes more prominent in the internal layers. "Palisading" of squamous epithelium at periphery. Compact, lamellar keratin formation ("wet keratin") is diagnostic. Dystrophic calcification is frequently seen, the cysts of craniopharyngiomas often contain cholesterol-rich, thick brownish-yellow fluid. Papillary craniopharyngioma contain both solid sheets of cells and papillae lined by well-differentiated squamous epithelium. These tumors usually lack of lamellar keratin, calcification, cysts, peripheral palisading of squamous cells, and a spongy reticulum.
