Acne is a skin condition characterized by plugged pores, inflamed pimples and deeper, tender lumps (cysts). It usually occurs in the areas of increased oil (sebaceous) glands – face, chest and back.


Rosacea is a common, chronic but treatable condition that typically affects the central third of the face. The underlying cause(s) of rosacea are unclear but involve blood vessel factors such as increased blood flow, increased tissue fluid and interaction with the nervous system via flushing.


Moles are pigmented skin growths medically known as nevi. Moles are usually brown but can vary in color (skin colored to pink to light brown to dark brown to blue to black). Moles can be present at birth, but most moles develop during childhood until the age of 20.


Psoriasis is a treatable autoimmune disease that affects the skin and nails. Twenty percent of people who have psoriasis will have involvement of their joints, presenting as arthritis. There are five types of psoriasis: plaque, guttate, inverse, pustular and erythrodermic.



Warts are a viral infection of the skin caused by the human papilloma virus (HPV). They can appear anywhere on the skin but are more common in areas of minor breaks or open skin.

On the soles of the feet, warts are called "plantar warts". Similarly warts on the palms may be termed "palmar warts". Sometimes they may appear in clusters referred to as mosaic warts or may be minimally elevated flat warts. In women genital warts in the cervical area may lead to cervical cancer.


Skin cancer is the most common cancer and is increasing at a rapid rate. There are many types of skin cancer but the most common types are basal cell carcinoma, squamous cell carcinoma and malignant melanoma. The cause of these cancers is complex and involves multiple factors including ultraviolet light exposure (sunlight, tanning beds), genetics and changes in genes (DNA) that control cell growth.

Other types of skin cancer such as lymphomas and sarcomas involve abnormalities of cellular control genes. Internal causes such as those arising in the colon, prostate, breast and lung can spread to the skin or scalp and can appear as a lump or bump.
