The human axillary apocrine glands were observed by scanning electron microscopy. The axillary apocrine glands revealed three types of apocrine secretion: macroapocine, microapocrine and intermediate apocrine. In the macroapocrine type of secretion, a round projection, which lacked microvilli bulged up from the surface of the secretory cell. In the microapocrine type, the tips of microvilli which covered the large apocrine protrude were expanded and separated. In the intermediate apocrine type, several secretory protrubrances were formed at the luminal portion of the cell. Each protrubrance was composed of several swollen microvilli united. Small round pores were observed on the luminal plasma membrane. They seemed to represent the state of eccrine secretion, but nothing definite was learned about their nature. Some secretory cells had the luminal plasma membrane ruptured. They might not indicated a state of holocrine secretion, but were assumed to exhibit a deciduous phenomenon in the metabolism of secretory cells. The cracked surfaces of secretory cells were observed to confirm the presence of nuclei and cell organelles.
