An atypical or dysplastic mole is one that often looks different clinically and, when biopsied, has atypical features under the microscope; hence it is called atypical due to the irregular or unusual features.

The Expert Opinion describes atypical or dysplastic moles in terms of potential health risks as well as formation of moles and their relationship to melanocytes. The expert opinion also discusses diagnosis, treatment, examples, and other general information regarding dysplastic moles.

Xeomin® for Wrinkles

Xeomin® (incobotulinumtoxin A) is a form of botulinum toxin used to reduce the appearance of aging skin, including wrinkles and furrows. Xeomin® has been used in recent years to treat a neurological disorder called cervical dysontia. It was approved by the FDA in 2012 for the treatment of glabellar furrows, deep wrinkles on the forehead. Doctors may also choose to use Xeomin® to treat wrinkles around the eyes, lines in the upper lips, drooping of the corners of the mouth, as well as prominent bands in the neck. Similar to other forms of botulinum toxin, such as Botox® and Dysport®, Xeomin® is injected into the skin to temporarily immobilize the facial muscles that cause facial wrinkles and frowns.


Asthma Types & Severity

There are different types of asthma that may be categorized according to the primary trigger or pattern of symptoms. For instance, exercise-induced asthma (EIA) is triggered by exercise, and allergic asthma is triggered by allergens. Asthma may also be classified according to the severity of symptoms. This classification is helpful for establishing an asthma treatment plan.
