Erythema ab igne and its association with cannabinoid hyperemesis syndrome: a case report

The erythema ab igne is an uncommon skin disorder related to repeated heat exposure such as open fires or heating pads. Cannabinoid hyperemesis syndrome is an entity including several symptoms such as nausea, vomiting or frequent abdominal pain following marijuana use. Most of those symptoms can be relieved by hot showering or baths. Recently in the literature, erythema ab igne has been associated with cannabinoid hyperemesis syndrome because cannabis users tend to resort to heating pads to relieve persistent abdominal pain.
We report the case of a patient with recurrent vomiting and abdominal pain attributed to cannabinoid hyperemesis syndrome, whose physical examination revealed an erythema ab igne.
