Background: Congenital dermoid sinus of the anterior chest region (CDACR) is a rare developmental anomaly. Therefore, the aim of our study was to draw attention to this underrecognized lesion.
Methods: From 2011 to 2019, our study group included 11 patients who presented to our hospital with pits and masses of their anterior chest walls. All lesions were surgically excised with histologic confirmation of the diagnosis of CDACR. The medical records of these patients were reviewed for the following data: patient age, gender, clinical characteristics of the lesion and site of involvement, department first visited, diagnostic evaluation, management, postoperative complications, and histopathological findings.
Results: There was a clear left-sided predominance, with 10/11 cases occurring on the left and a female predominance of eight cases out of 11. Although the pits were present at birth, the mean age at presentation was 19.7 months. All patients showed clinical signs of infection at the time of presentation and were treated with antibiotics. Seven patients had a history of abscess formation treated with incision and drainage. Ultrasound was performed in eight patients. In all cases, the lesions, including pit and sinus, were completely excised.
Conclusions: Congenital dermoid sinus of the anterior chest region is likely underrecognized. We encountered a high frequency of complications such as infections or abscesses prior to surgical excision. Complete excision of CDACR is not technically difficult. Therefore, surgical removal should be considered, even for asymptomatic lesions, to avoid future complications and for cosmesis.
