Congenital dermoid fistula of the anterior chest region.

Sir, Congenital dermoid fistula (CDF) of the anterior chest region is a congenital cutaneous fistula that has its skin orifice at the sternoclavicular joint and a tract extending caudally in the subcutaneous tissue (1). Since CDF is rare it is sometimes incised and drained after misdiagnosis as an inflamed atheroma, but the affected region and the pathological and clinical findings are, in fact, characteristic. Only limited cases without radiological findings have been documented previously. We report here a case of CDF with computed tomography (CT) images.
