Lichtenberg flowers are seen in: CMC (Vellore) 14
**Core Concept**
Lichtenberg flowers are a manifestation of electrical discharge in a dielectric medium, typically seen in the context of electrical injuries. This phenomenon occurs due to the ionization of air and the subsequent formation of a conductive path for the electrical current to follow.
**Why the Correct Answer is Right**
Lichtenberg flowers are characteristic of high-voltage, low-current electrical discharges, which can cause tissue damage and charring at the point of contact. The electrical discharge creates a pattern of branching, tree-like structures on the surface of the skin, resulting from the ionization of air and the subsequent breakdown of the dielectric barrier. This phenomenon is often seen in cases of electrical injuries, particularly those involving high-voltage electrical sources.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Lichtenberg flowers are not typically associated with lightning strikes.
**Option B:** This option is incorrect because arborescent burns are not a specific type of burn pattern associated with electrical discharges.
**Option C:** This option is incorrect because electrical burns can cause a range of burn patterns, but Lichtenberg flowers are a specific manifestation of high-voltage electrical discharges.
**Clinical Pearl / High-Yield Fact**
Lichtenberg flowers are a classic sign of high-voltage electrical injury, and their presence should raise suspicion for an electrical cause of the patient's symptoms.
**Correct Answer: D. Electrical injuries.
