#allergid
- Allergid — A secondary cutaneous eruption, of an allergic or inflammatory nature, appearing on the skin as a distant immune response to a primary infectious focus (bacterial, fungal, or parasitic) in the body, without the original pathogen being present in the secondary dermatological lesions. Structurally, allergids (such as mycids or tuberculids) reflect a cell-mediated dermo-epidermal hypersensitivity reaction.
