This congenital newborn desease is reported mainly in domestic animals. The present study described EI in a 13 day-old, female crossbred Holstein calf. Gross examination showed epithelium agenesis of two front and hind limbs skin around the carpal and tarsal joints, and also extensive areas of the metacarpal and metatarsal regions.
