Ultrastructure of the neurohypophysis
Microscopy Research and Technique, 1992AbstractThis review summarizes our current knowledge of the ultrastructure of the human neurohypophysis and includes comments on its anatomy, physiology, and embryology. The neurohypophysis represents a unique tissue having neural and endocrine characteristics and possessing ultrastructural features distinct from those of conventional endocrine organs ...

Xanthelasma from both upper eyelids of a patient were examined by electron microscopy. The cytoplasm of the foam cells was filled with lipid droplets that were not bounded by a membrane. The lipid itself dissolved out during tissue preparation despite osmium or glutaraldehyde-osmium fixation, indicating that the lipid is highly unsaturated.

The Ultrastructure of Rhabdomyosarcoma
American Journal of Clinical Pathology, 1970The ultrastructural features of one embryonal and two pleomorphic rhabdomyosarcomas in adults are described. The presence of thick myofilaments in formations suggesting sarcomeres and a rare arrangement of mitochondria in tandem allow for identification of the spindle cells in embryonal rhabdomyosarcoma as skeletal muscle cells.

The fine structure of five cerebral aneurysms, four early aneurysmal changes, and three arteriovenous aneurysms (two cerebral and one spinal) were investigated from surgical and autopsy specimens. Each lesion was characterized by thickening, lamination, redundancy, and separation of basement membranes, abundant cellular debris, and a paucity or absence

The ultrastructure of oligodendrogliomas
Neurosurgical Review, 1981Seven Oligodendrogliomas (2 with uniform cell type, 4 with cellular or tissue variability, and 1 with glioblastomatous changes) were examined ultrastructurally. The tumor cells were of two principal types with morphologic transitions between the two main types.

The ultrastructure of a keloid
Journal of the American Academy of Dermatology, 1980An active, symptomatic keloid from a 57-year-old woman was examined by both light and electron microscopy. The lesion was found to be comprised entirely of myofibroblasts. Fibroblasts in keloids can apparently undergo full transition to this smooth muscle-like cell.

Ultrastructure of a “Pineocytoma”
Journal of Neuropathology & Experimental Neurology, 1975The commonest pineal gland tumor, the germinoma, is more apparently related to germ cells than to pineal cells. Although ultrastructural studies of this tumor have confirmed this similarity, comparable characterization of a pineocytoma has not been reported, due to its rarity.

Ultrastructure of dermatofibroma
Archiv f�r Dermatologische Forschung, 1973Eight dermatofibromas were studied by electron microscopy. The essential cell was the fibroblast, characterized by a well developed rough endoplasmic reticulum (RER), a distinct Golgi zone and large numbers of cytofilaments. The fibroblast of the dermatofibroma was engaged in collagen production and fat storage.

Guanophores in the back skin of the adult tree frog have been studied with an electron microscope. The cytoplasm is characterized by numerous needle- or platelet-like clear spaces which are incompletely surrounded by their own limiting membranes.
