[Melanocytic population of buccal mucosa of patients with lichen planus]
Abstract:
The authors have studied the melanocytic population in oral mucosa (Dihydorxyphenyl alanine, silver impregnation, hematoxilin-eosin) of 20 patients (10 with Lichen ruber planus and 10 with Alopecia areata). The melanocytic population in oral mucosa ranges from 605 to 1555 cells per m2 (964 +/- 312 on the average). Normal population, in case of lichen planus of oral mucosa, is disturbed in the regions of the pathological process. The deviations established are discussed.

Pigmentation
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...

Skin Cancer
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.
