Acanthosis Nigricans
Dermatology
Acanthosis nigricans causes patches of skin to become darker, thicker and velvety to the touch. It appears most often in body folds — the neck, armpits and groin. It is usually a sign of something else going on in the body, most commonly insulin resistance or prediabetes, so finding it is often the first step toward diagnosing another condition.

What side effects should I watch for, and when should I contact you? Is this condition contagious, inherited, or linked to anything else in my health?

Actinic Keratosis
Dermatology
An actinic keratosis is a rough, scaly patch that forms on skin damaged by years of sun exposure. The patches are usually easier to feel than to see.

Alopecia Areata
Dermatology
Alopecia areata is an autoimmune condition in which the immune system attacks hair follicles, causing hair to fall out in round, smooth patches.

Athlete's Foot

Birthmarks
