Only 15 cases of pilonidal sinus of the umbilicus have so far been reported. A 16th case is described; it supports the theory of acquired origin of the disease. The case fulfilled the criterion for pilonidal sinus--the 36-year-old man had a hair in the infected umbilical cyst. The cyst and umbilicus were excised. The umbilicus was not reconstructed because of the danger of recurrence. It is recommended that a careful search be carried out for hair in all patients with an infected umbilicus.
迄今为止，仅报告过15例脐部藏毛窦病例。本文描述了第16例病例；该病例支持了该病后天起源的理论。该病例符合藏毛窦的诊断标准——这位36岁男性的感染脐部囊肿内有毛发。囊肿和脐部均被切除。由于存在复发风险，未对脐部进行重建。建议对所有脐部感染患者仔细检查是否有毛发。
