Allergies
Alpha-gal allergy - Alpha-gal syndrome is likely caused by a hypersensitivity reaction to the Alpha-gal (Galactose-alpha-1,3-galactose) sugar molecule introduced by ticks while feeding on a human host. The immune reaction can leave people with an allergy to red meat and other mammalian derived products.
Poikiloderma of Civatte is a cutaneous condition and refers to reticulated red to red-brown skin patches with telangiectasias. It is identifiable as a reddish-brown discoloration on the side of the neck, usually on both sides. It is more common in lighter-skinned individuals, in females rather than in males and more often affects middle-aged to elderly women. This disease is basically a change of the skin due to dilation of the blood vessels in the neck. "Civatte" was the French dermatologist who first identified it in the 1920s. See also
