  • Abstract
  • Look Inside

The histogenesis of craniopharyngiomas was im-munohistochemically studied on the basis of cyto-keratins (CK) expression, with special reference to histological subtype, i. e., the squamous type (Sq) and adamantinomatous type (Ad). Alcian-Blue staining and immunohistochemical expression of secretory component were also studied to assess secretory activity.

Although combined expression of simple-, stratified-, and skin- type CK was detected in both Sq and Ad, the pattern of expression in Sq and Ad was different. Sq displayed epidermal differenti-ation of CK, and secretory activity was limited to the apical cells of Sq.
