Abstract

Introduction

Suprapubic dermoid sinuses are rare congenital anomalies resulting from incomplete ectodermal separation during embryogenesis.

Case presentation

A 9-month-old male infant presented with a midline suprapubic dimple noted since birth and no other medical history. Ultrasound revealed a superficial sinus tract, and Magnetic Resonance Imaging (MRI) confirmed a well-defined, blind-ending tract without any deeper communication. A complete excision was done in the operating room under general anesthesia. We guided the dissection of the sinus with methylene blue injected in it. The histopathology confirmed the diagnosis of a dermoid sinus lined with keratinized squamous epithelium containing dermal appendages. The postoperative recovery was uneventful. No recurrence was observed at the 1-month, 3-month, and 6-month follow-up visits.

Conclusion

Dermoid sinuses, although rare, should be included in the differential diagnosis of midline congenital dimples in infants.

9个月婴儿耻骨上皮样窦1例

耻骨上皮样窦是一种罕见的先天性畸形，是由胚胎发生时外胚层分离不完全引起的。病例介绍：一名9个月大的男婴，自出生以来就有耻骨上中线酒窝，无其他病史。超声显示浅表窦道，磁共振成像（MRI）证实了一个明确的，无任何深层沟通的盲尾窦道。在全身麻醉下在手术室进行了完全切除。我们在鼻窦内注入亚甲基蓝，引导鼻窦剥离。组织病理学证实了皮样窦内衬角质化鳞状上皮，含有真皮附属物。术后恢复顺利。随访1个月、3个月、6个月均无复发。结论皮样窦虽少见，但应作为婴儿先天性中线酒窝的鉴别诊断之一。
