Three tumors were adamantinomatous craniopharyngiomas (ACPs) and one was a craniopharyngioma of an unknown subtype. A Histopathological examination reveals an ACP characterized by squamous epithelium arranged in a trabecular pattern as well as nodules of wet keratin in patient 1. B Postoperative pathology shows an ACP in patient 2. C Postoperative pathological examination shows a craniopharyngioma in patient 3; however, the specific subtype cannot be accurately identified.
