Such a lesion could be considered ectopic (ektopos is Greek for “out of place”) and may be benign and of no systemic consequence, or it may be associated with an extracutaneous and potentially serious condition. Various types of ectopic tissue and their characteristic locations are listed in Table 18-1.
