Phlebitis (inflammation of a vein): Usually occurs along a vein pathway (often after IV cannulation or trauma). Skin shows linear redness, warmth, tenderness, and swelling following the vein. Sometimes a cord-like induration of the vein is felt. More acute, painful, and sharply localized compared to eczema. The picture you shared: Shows diffuse redness with scaling, dryness, lichenification, and excoriations. Lesions are mainly in the flexural crease (elbow bend), not following a vein. No obvious cord-like structure or linear track of a vein is seen. 👉 This fits eczema/dermatitis (most likely atopic), rather than phlebitis. ✅ So: Not phlebitis → most likely chronic dermatitis (eczema). Do you want me to make you a short exam-style differentiating table: Phlebitis vs Dermatitis, so it’s easy to recall?
