RESUMO
Pilonidal sinus is common in the sacrococcygeal region. It is rare at the umbilicus. Incidence being 0.6%, we report a case of umbilical pilonidal sinus treated in our hospital. A 20-year-old male patient was admitted to our hospital with complaints of purulent discharge from the umbilicus since 3 months. Patient was posted for omphalectomy. Intraoperatively, a tuft of hair was found in a sinus tract communicating with the umbilicus. Histopathological evaluation was compatible with pilonidal sinus disease. There are only a few reports of the umbilical pilonidal sinus in the literature. Umbilical sinus tract differs from the sacrococcygeal variety in the absence of multiple tracts and low recurrence rates. Treatment options and differential diagnosis are discussed in the article.
