Epithelial coccygeal duct

Epithelial coccygeal duct (coccyx cyst) is a narrow, long channel 2-3 cm long, lined with epithelium. It contains hair follicles, sebaceous glands and opens on the skin of the buttock fold with one or more point holes.

When the primary openings of the passage are blocked, its contents stagnate, which leads to the multiplication of microorganisms and purulent inflammation. The course expands, its walls undergo purulent inflammation, and the infection spreads to the surrounding subcutaneous fatty tissue. If the abscess opens on its own, a secondary fistula opening is formed.

The course of the disease is wave-like, depending on the presence or absence of an inflammatory process. The contents of the cyst can be hair, fragments of teeth, secretion of sebaceous or sweat glands.

Treatment of coccyx cyst is only surgical:

  • with suppuration – opening of the abscess,
  • with chronic inflammation – planned radical excision of the cyst with plastic skin and partial suturing of the wound. Surgical intervention is aimed at eliminating the main source of inflammation (the canal with all primary openings, secondary fistulas, changed by surrounding tissues).

It is recommended to remove the coccygeal duct as soon as it has been diagnosed, even in the absence of inflammation, as it is a potential source of inflammation with the formation of purulent infiltrates and fistulas.
