PATHOLOGY

Detailed explanation-1: -Nodule A large ( 0.5 – 5.0 cm ), firm lesion raised above the surface of surrounding skin. It is the depth of involvement that differentiates a nodule from a large papule.

Detailed explanation-2: -Squamous cell carcinoma-the second most common form of skin cancer that affects about 20 percent of patients with skin cancer. This highly treatable cancer is characterized by red, scaly skin that becomes an open sore.

Detailed explanation-3: -A capillary malformation (also known as a port-wine stain or port-wine birthmark), is a flat, sharply defined pink to red discoloration of the skin. A person may have one or multiple capillary malformations. These lesions may cover a large surface area or may be scattered and appear as smaller spots of color.
