They also chew on the bottom of their feet/toes, inside of their mouth, cheeks, and/or lips, causing blisters in and outside of the mouth.

Symptoms and signs. Green nail syndrome (chloronychia or Goldman-Fox syndrome) is characterised by discolouration of the infected nail, inflammation of the skin around the nail known as paronychia, and an odour resembling fruit. The colour may range from light or blueish green or yellow-green to darker green or black.
Acute paronychia is an infection of the folds of tissue surrounding the nail of a finger or, less commonly, a toe, lasting less than six weeks. [4] The infection generally starts in the paronychium at the side of the nail, with local redness, swelling, and pain.
The skin between the fingers and toes may be fused (cutaneous syndactyly). This disorder is also characterized by widely spaced eyes (ocular hypertelorism), an abnormally large head size ( macrocephaly ), and a high, prominent forehead.
