My partner has a very red rash in neck area, somewhat like a moth shape, with long body and winging out at the sides. He is English, has fairish skin generally, but a quite red rash has developed over his throat area - over the adams apple and down on to the chest area.
Hi, It could be due to sunlight, the condition called as photosensitive dermatitis. But I recommend you to visit your Dermatologist to confirm the diagnosis as there are multiple causes for red rash in neck area. Hope I have answered your query. Let me know if I can assist you further.
