A 2-year-old healthy white girl presented with an asymptomatic, skin-colored, polypoid, exophytic mass on the skin overlying the coccygeal region (Figure 1). The lesion, which measured approximately 0.4 cm in maximum diameter, was congenital and had not changed since birth. The results of the patient’s physical examination were otherwise normal. Ultrasound examination of the cutaneous and subcutaneous tissues and radiography of the lumbosacral column revealed no abnormalities. For aesthetic and diagnostic reasons, an excision of the lesion was performed (Figure 2 and Figure 3).
