The Third

A reevaluation of the silver methenamine reaction as an electron stain has ensued from recent use of glutaraldehyde fixation alone. By this technique, three cell types of rat adrenal medulla were found: (i) the norepinephrine-containing cells showed selectively stained, irregular, black granules; (ii) the epinephrine-containing cells showed round, light-grey granules; and (iii) the third cell type showed round granules like those of epinephrine-containing cells, but black in color, similar to those of the norepinephrine-containing cells.

Nerve Sheath

Abstract Reports of melanotic nerve sheath tumors of Schwann cell origin are rare, only three having been found in the literature. Two new cases of spinal intradural melanotic nerve sheath tumors are reported and the literature is reviewed. Controversy has arisen in regard to the origin of melanin within these tumors. Electron microscopic study of one of our cases indicates that the Schwann cell is capable of producing melanin. The available evidence suggests that ultrastructural identification of the cell type in these pigmented tumors is essential in plotting the therapy and prognosis of patients with melanotic nerve sheath tumors.
