Coccygeal glomus
Section of an irregular nodule of the glomus coccygeum. X 85. The section shows the fibrous covering of the nodule, the bloodvessels within it, and the epithelial cells of which it is constituted.
Latin	glomus coccygeum
Gray's	subject #277 1281
Artery	median sacral artery

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

[edit] Anatomy

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.

[edit] Clinical significance

It may appear similar to a glomus tumor.^[1]
