[A newborn infant with a tail].

A case of a male baby with a tail is described. The tail was surgically removed. Histopathological investigation showed that it was covered with hairless skin. It contained adipose and fibrous tissue, arteries, veins and nerves, but no cartilage, bone or muscle. In most cases of these caudal appendages surgical excision is sufficient, although an underlying anomaly should be excluded radiographically.
