FINE STRUCTURE OF ECCRINE SWEAT GLAND ADENOMA CLEAR CELL TYPE

[摘要] The ultrastructural features of 2 clear cell eccrine sweat gland adenomas are described. The clear tumor cells are shown to closely replicate the fine structure of the clear cells of the eccrine secretory coil. Each has a high glycogen content and a similar system and distribution of intracellular organelles. However, the most conclusive evidence that the clear tumor cells is biologically related to the eccrine secretory clear cell is provided by the marked similarity of their complex intercellular membrane systems.
