A MIDLINE, POSTERIOR cervical mass was found during a physical examination of a full-term female infant (Figure 1). The mass was tubular with a wide sessile base and measured 3×3×4 cm. The base and most of the cylindrical wall were covered by a full thickness of skin, while the dome was covered by a violaceus, tough membrane. No leakage of fluid from the mass was observed and the infant's neurological examination results appeared to be normal.
