The interdigital webbing and foot pads are examined for discoloration, abrasions, and other conditions. In waterfowl, such as ducks, Bmp antagonists inhibit apoptosis, leading to webbed feet ( Weatherbee et al. When interviewed, the patient denied any pruritus and was not noted to be scratching her skin during her initial evaluation. Interdigital cysts are usually red and might be filled with blood or pus.
