Affected infants born encased in a collodion membrane taut, shiny, translucent membrane appearing as an extra skin layer with armorlike plates, distributed throughout the body, which severely restrict movement.
Other clinical features are often associated such as palmoplantar keratoderma, failure to thrive, short stature, malformed ears and digits, nail deformities and alopecia. Early complications result from infection due to fissuring of the hyperkeratoic plates and respiratory distress due to physical restriction of chest wall expansion.
