Plantar Warts – Definition

Plantar warts are growths on the soles of the feet. They are often mistaken for corns or calluses. The warts are different because a virus causes them.

They grow in clusters and are usually flat. A plantar wart can often be distinguished by numerous black dots visible on their surfaces. Although plantar warts are generally harmless, their location beneath the feet can make them very tender. They also have a tendency to spread locally to other sites on the foot and elsewhere.

Pemphigus – Definition

Pemphigus is a group of rare autoimmune disorders. It causes large skin blisters. The immune system normally protects against germs and other foreign invaders. In this case, the immune system mistakenly attacks your own skin and mucus membranes. There are three forms of the disease:

  • Pemphigus vulgaris — most common type of pemphigus; lesions may extend deep into the layers of the skin
  • Pemphigus foliaceus — produces more superficial lesions
  • Paraneoplastic pemphigus — most serious type; usually occurs in someone who has cancer

Pemphigus – Causes

The immune system produces antibodies. These cause the skin and mucus membranes to break out in blisters and burn-like sores. What causes the body to attack itself is not known. Sometimes a drug can cause symptoms.

Moles – Definition

Moles are spots on the skin where pigmented cells have clustered together. They typically appear as light to dark brown spots on the skin that are either flat or raised. Most people have benign moles, which are harmless.

Moles that become atypical (called dysplastic nevi) might eventually become melanoma. Melanoma is a form of skin cancer. Moles that change or look atypical need to be evaluated by your doctor or a dermatologist.

Melanoma

(Cutaneous Melanoma; Malignant Melanoma)

Melanoma – Definition

Melanoma is a skin cancer. It affects skin cells called melanocytes. These cells produce skin color. They also give moles their dark color. Under normal conditions, moles are benign skin tumors. This means non-cancerous. Sometimes a mole can develop into melanoma. A new mole may also be an early melanoma.

Melanoma is less common and more dangerous. They are much more likely to spread to other parts of the body.
