Adamantinomatous craniopharyngioma
The patient underwent an endoscopic transsphenoidal debulking of the recurrent craniopharyngioma, followed by postoperative radiotherapy.
Histology
Paraffin sections show small fragments of craniopharyngioma. These consist of epithelial islands within a loose fibrous stroma. The epithelial islands show a peripheral basaloid layer, central squamous epithelium and a stellate reticulum layer. Several cystic spaces filled with loose amorphous eosinophilic material are noted and there are several foci of dystrophic calcification. No mitotic figures or areas of necrosis are identified.
Final diagnosis
Adamantinomatous craniopharyngioma.
This case illustrates the typical pathological and radiological features of adamantinomatous craniopharyngioma.
