Breakfast, lunch, and dinner sign refers to a pattern of small bumps of the skin seen following insect bites.[2] Generally three to five appear close together, in a cluster or line, and at the same time.[1][3] Each bump is mostly smaller than 1cm, appear pinkish, and may itch.[3] The sign is typically seen on exposed parts of the body such as the face, neck, arms, or legs.[3]
The cause is the bites of insects such as fleas and bed bugs.[3] Unable to fly, fleas and bed bugs generally jump or walk to bite, causing the bite marks to appear in a line.[4][5] An enzyme in the saliva of the insect may cause a local allergic reaction, resulting in a larger bump that is itchy.[3] Diagnosis is by its appearance.[3]
Treatment includes antihistamines to reduce itch, and applying a steroid cream to reduce redness and swelling.[3] Prevention lies in insect control within the environment.[3] It is common.[3]
