Research Abstract

1. Within the morphological studies on human intermediate lobe of the pituitary, electron microscopical study of intermediate lobe cysts was done. Materials were obtained from three patients undergone a microsurgical treatment. Intermediate lobe cysts were divided into four groups; Rathke's cyst (or Rathke's cleft), duct or ductal cyst, terminal portion of the pituitary tubular gland, and irregular gland-like structure. Epithelial lining in the wall of the Ratlike's cyst (or Rathke's cleft) was composed of luminal epithelia such as ciliated cells or mucous cells, and basal epithelia such as adenohypophysial cells or squamous cells. Duct or ductal cyst was thought to lie between Rathke's cyst (or Rathke's cleft) and terminal portion of the pituitary tubular gland. A total system with continuity from Rathke's cyst (or Rathke's cleft), via duct or ductal cyst, to terminal portion of the tubular gland might be called "tubular system in the intermediate lobe of the pituitary".
2. At present, … More the definition of Rathke's cleft cyst (RCC) and craniopharyngioma, the relationship between RCC and craniopharyngioma, or the pathogenesis of RCC and craniopharyngioma are still equivocal. Irrespective of designation as RCC or craniopharyngioma, a clinico-pathological review was done in the patients with parasellar cuboidal-columnar epithelial cystic lesion. We reviewed 14 patients who had undergone surgical treatment, and an aged whose lesion had been incidentally found at autopsy. Cystic lesions have been classified on the basis of neuroradiological location of the lesion, especially in relation to the pituitary (grouping), and histology (typing). Group A: intrasellar lesion with or without suprasellar slight extension (2 cases), Group B: intra- and suprasellar lesion (9 cases), Group C: suprasellar lesion (3 cases); Type I: cuboidal-columnar epithelial lesion with or without stratified squamous epithelium (12 cases), Type II: cuboidal-columnar epithelial lesion with squamous epitheliomatous growth (3 cases).
