Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. [1] It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma). [1] [2] In women, melanomas most commonly occur on the legs; while in men, on the back.

A seborrheic keratosis is a non-cancerous skin tumour that originates from cells, namely keratinocytes, in the outer layer of the skin called the epidermis. Like liver spots , seborrheic keratoses are seen more often as people age.
Skin cancer is the most commonly diagnosed form of cancer in humans. [11] [12] [13] There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma. [1] The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).

INK4A, also known as p16, is a tumor suppressor gene and is found to have hypermethylated promoter regions in 10- 20% of melanoma cells and is involved in 40- 87% of gene alterations in melanoma cases (Gonzalgo et al., 1997). This means that 10- 20% of the time there is an epigenetic change in the INK4A gene, and 40- 87% of the time there is a ...
Many seborrheic keratoses on the back of a person with Leser–Trélat sign due to colon cancer. The Leser–Trélat sign is the explosive onset of multiple seborrheic keratoses [1] (many pigmented skin lesions), [2] [3] often with an inflammatory base. This can be a sign of internal malignancy as part of a paraneoplastic syndrome. In addition ...
Melanoma is a malignant proliferation of melanocytes and the most aggressive type of skin cancer. Subcategories This category has only the following subcategory.
It typically progresses very slowly and can remain in a non-invasive form for years. It is normally found in the elderly (peak incidence in the 9th decade), on skin areas with high levels of sun exposure like the face and forearms. Incidence of evolution to lentigo maligna melanoma is low, about 2.2% to 5% in elderly patients.
