Following this course, the attendee should be able to:
- Predict the effect of smoking on a specific dermatologic condition.
- Recognize skin diseases caused and aggravated by smoking
- Identify the mechanism of action of tobacco products on the skin.
In addition to a well known harmful role of smoking in several inflammatory skin diseases, such as psoriasis and hidradenitis suppurativa, there is a high risk of developing skin cancers among first- and second-hand smokers. The nicotinic class of cutaneous cholinergic receptors mediates, in part, the tumorigenic effect of tobacco nitrosamines. On the other hand, there is a negative association of smoking with certain skin diseases, such as pyoderma gangrenosum and pemphigus. The dichotomous effect of smoking can be explained through the nicotinic receptor-mediated action of nicotine on different cutaneous cell types involved in a particular disease.
