On physical exam, an engorged tick was found attached to the patient’s left upper back.  The underlying skin was nontender but mildly erythematous, without central clearing. The tick was gently removed with blunt angle forceps and sent for further analysis, which later revealed the specimen to be an American dog tick (Dermacentor variabilis).

The first photograph demonstrates a dendritic blister (Lichtenburg figure) on the medial aspect of his right foot where the ground current injury entered the patient's foot. Although no data exists regarding the sensitivity or specificity of Lichtenberg figures as skin findings, they are considered pathognomonic for lightning injuries and are not produced by alternating current or industrial electrical injuries. The second photograph demonstrates a 4 x 3 cm area of petechiae where the ground current injury exited the patient.
