Coccygeal glomus

The coccygeal glomus (coccygeal gland or body; Luschka’s gland) is placed in front of, or immediately below, the tip of the coccyx.

It is about 2.5 mm. in diameter and is irregularly oval in shape; several smaller nodules are found around or near the main mass.

It consists of irregular masses of round or polyhedral cells, the cells of each mass being grouped around a dilated sinusoidal capillary vessel.

Each cell contains a large round or oval nucleus, the protoplasm surrounding which is clear, and is not stained by chromic salts.
