Dermatologic manifestations associated with electronic cigarette use.

Introduction:
This text reviews the literature on cutaneous manifestations associated with electronic cigarette use. The authors aim to increase awareness of the potential side effects of electronic cigarettes, which have become increasingly popular in recent years.

Key Points:

* Electronic cigarettes, also known as e-cigarettes, are devices that utilize thermal energy to vaporize a liquid, creating an aerosol that can be inhaled to mimic the effects of tobacco smoking.
* hua et al. conducted a review of online e-cigarette forums and found that 13.9% of e-cigarette users reported a dermatologic symptom, including dermatitis, burns, acne, boils, bumps, blisters, and various other symptoms.
* The review discusses several cases of contact dermatitis caused by the release of nickel from e-cigarette devices. The nickel is transmitted through the device, irritating the dominant hand used to hold the e-cigarette.
* Thermal injuries can also occur due to lithium-containing batteries used in e-cigarettes. Poor product design, manufacturing failures, and low-quality materials can lead to a lack of internal thermal regulation, resulting in thermal runaway and burn injuries.
* Between 2015 and 2017, an estimated 2035 individuals with explosion and burn injuries from e-cigarettes presented to US emergency departments, a significant increase from previous years.
* Oral mucosal lesions (OMLs) have been associated with tobacco smoking, and the current literature does not demonstrate a reduced risk in the development of OMLs by switching from traditional cigarettes to e-cigarettes. In fact, an increased prevalence of OMLs has been demonstrated in e-cigarette users.
* Nicotine stomatitis, hyperplastic candidiasis, and black hairy tongue (BhT) are three types of inflammatory lesions in the oral cavity that have been found to be more prevalent in e-cigarette users.

Main Message:
The text highlights the potential dermatologic manifestations associated with electronic cigarette use, including contact dermatitis and thermal injuries. The use of e-cigarettes has become increasingly prevalent, and healthcare providers should be aware of these potential side effects. additionally, the text notes that oral mucosal lesions have been found to be more prevalent in e-cigarette users, indicating that further research is needed to determine the safety of e-cigarettes as a smoking cessation tool. Overall, the main message is that electronic cigarettes are not without risk, and healthcare providers should inform their patients of these potential side effects.
