We report an 18-year-old man with recurrent cellulitis of his umbilicus and surrounding skin. Thorough investigation revealed a foreign body as the source of his relapsing infection, a compact collection of terminal hair shafts. Spontaneously occurring stonelike foreign bodies resulting from the accumulation and concretion of keratinous and amorphous sebaceous material within the umbilicus are referred to as omphaliths. However, because the composition of our patient's foreign body is pilar in origin, we propose that the foreign body be designated as either an omphalotrich or trichomphalith. Alternatively, because the umbilicus and epithelium of the gastrointestinal tract are embryologically related, we suggest that our patient's hair-containing foreign body be referred to as a trichobezoar, which is used to describe exogenous foreign bodies composed of ingested hair in the gastrointestinal tract. The patient's cellulitis resolved without any subsequent episodes following the removal of his belly button bezoar.
我们报告了一名18岁男性，其脐部及周围皮肤反复发生蜂窝织炎。全面检查发现一个异物是其反复感染的源头，该异物是紧密聚集的终毛毛囊。脐部内因角质和无定形皮脂物质积聚和凝结而自发形成的石样异物被称为脐石。然而，由于我们患者异物的成分起源于毛发，我们建议将该异物命名为脐毛石或毛发脐石。另外，由于脐部与胃肠道上皮在胚胎学上相关，我们建议将我们患者含毛发的异物称为毛粪石，毛粪石用于描述胃肠道内由摄入毛发组成的外源性异物。在切除肚脐粪石后，患者的蜂窝织炎得以解决，且未再复发。
