We describe a male neonate who presented at birth with a compressible dermoid cyst that extended from the floor of the mouth to the midline of the neck. Ultrasonography revealed a fluid-filled sublingual mass. Magnetic resonance imaging performed when the patient was 1 week old demonstrated a 2-cm, cystic, left-sided, sublingual mass that crossed the midline without extension inferior to the mylohyoid muscle. At 3 months of age, the patient developed a 1-cm, solid, submental mass. At the time of surgery, the lesion had a fibromembranous tract that extended through the myolohyoid muscle to a 1-cm cyst in the submental region. Histologic sections depicted 2 dermoid cysts and a connecting fistula. This case represents the first report (to our knowledge) of a dermoid cyst presenting in a neonate as a mass in the floor of the mouth with extension to the midline of the neck.
我们描述了一名男性新生儿，其出生时即出现一个可压缩的皮样囊肿，该囊肿从口腔底部延伸至颈部中线。超声检查显示舌下有一个液性肿块。患儿1周大时进行的磁共振成像显示，左侧舌下有一个2厘米的囊性肿块，越过中线且未延伸至下颌舌骨肌下方。患儿3个月大时，颏下出现一个1厘米的实性肿块。手术时，病变有一条纤维膜性管道，穿过下颌舌骨肌延伸至颏下区域一个1厘米的囊肿。组织学切片显示有2个皮样囊肿和一个连接性瘘管。据我们所知，该病例是皮样囊肿在新生儿中表现为口腔底部肿块并延伸至颈部中线的首例报告。
