Pilonidal sinus of the umbilicus

Insights

This case report details a rare instance of umbilical pilonidal sinus, supporting its acquired origin. The study highlights the importance of searching for hair in infected umbilical cysts.

Area of Science:

  • Medicine
  • Surgery
  • Dermatology

Background:

  • Pilonidal sinus typically affects the sacrococcygeal region.
  • Umbilical pilonidal sinus is an extremely rare condition, with only 15 previous cases reported.

Observation:

  • A 36-year-old male presented with an infected umbilical cyst.
  • A hair was found within the infected umbilical cyst, a key diagnostic criterion for pilonidal sinus.

Findings:

  • The 16th reported case of pilonidal sinus of the umbilicus was successfully treated by excision of the cyst and umbilicus.
  • The umbilicus was not reconstructed due to the risk of recurrence.

Implications:

  • This case supports the theory that umbilical pilonidal sinus is acquired, likely due to foreign bodies like hair.
  • Clinicians should consider searching for hair in all cases of infected umbilical cysts to aid diagnosis and management of this rare condition.
