The patient has erythema ab igne, C, a condition that is associated with long-term application of heat. The pattern follows the reticular blood vessels; the heat causes mild inflammation, which results in erythema and pigmentation. Discontinuation of heat application usually results in cosmetic improvement.
Livedo reticularis is symmetric. Confluent and reticulated papillomatosis occurs on the trunk and produces scale. Contact dermatitis and psoriasis both produce itching.
