Abstract:
Dermoscopic images of histologically proven pigmented basal cell carcinomas (BCC) were retrospectively assessed to compare the dermoscopic features of BCC of 3 mm or less in diameter (n = 6) with BCC of 4-6 mm in diameter (n = 11). All lesions lacked the presence of a pigment network. BCC with a diameter of 3 mm or less had fewer positive dermoscopic features compared with the 4-6 mm in diameter BCC. Multiple blue-gray globules and large blue-gray ovoid nests were frequently present. Dermoscopy is a useful tool for early diagnosis of pigmented BCC, even when they are small.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
