| • | ethyl acrylate – nail tip glues patch test with dried crazy glue on a band-aid X 48hrs; clinical – paronychia, fissured finger tips and eyelid dermatitis; tips need to be off for two months before improvement expected; |

Perioral excematoid eruptions – cinnamon flavoring and peppermint in dentifrices and chewing gum; other dental materials
Photoallergic contact dermatitis – often caused by sunscreens in cosmetics; “chemical free” physical sunblocks should be okay (titanium dioxide or zinc oxide)
Systematized contact
