Abstract
INTRODUCTION: Congenital dermoid sinus which is a rare congenital anomaly of the anterior chest wall (CDACR) is frequently misdiagnosed or mistreated. This report aims to raise awareness about this condition and share experience based on a demarcation technique for anomalous tissue. PRESENTATION OF CASE: A case of surgically treated CDACR in our clinic and subsequently confirmed through histopathology was chosen. Health records such as, demographics, visits, imaging modalities, management, outcome, and histopathology were reviewed of the patient. DISCUSSION: Our patient aged 4 years underwent ultrasonography, which revealed a dermoid sinus on her right anterior chest. This diagnosis was later confirmed via histopathology after the excision of the sinus, which was facilitated by a mix of methylene blue and fibrin glue. The incision healed well without any complications. CONCLUSION: Thus, it was found that CDACRs are those rare congenital anomalies requiring immediate excision to prevent recurrent infections or complications. Knowing how to identify and deal with them is essential.
