The man’s nasal lesion was in all likelihood a blue nevus. Blue nevi are visible manifestations of dermal melanocytosis that occur in solitary blue or gray-blue papules. The most common sites of ...
Another name for these moles is “dermal nevi.” The melanocytes that make up an intradermal nevus are located in the dermis (below the dermo-epidermal junction). This mass of melanocytes pushes the cells above it upward, resulting in the flesh-colored bump that is noted on the surface of the skin. A dermal nevus is a non-cancerous skin tumour made up of specialized cells called melanocytes. Melanocytes produce melanin, the pigment that gives skin its colour.
dermal nevus, The term “dermal” is used because the melanocytes in a dermal nevus are located in the dermis, a layer of skin below the surface. An intradermal nevus is another name for a classic mole or birthmark. It typically appears as an elevated, dome-shaped bump on the surface of the skin. An intradermal nevus is a classic type of mole or birthmark, with the same degree of pigmentation as the surrounding skin. It appears as an elevated, dome-shaped bump on the surface of the skin.
dermal nevus, A melanocytic naevus (American spelling ‘nevus’), or mole, is a common benign skin lesion due to a local proliferation of pigment cells (melanocytes). It is sometimes called a naevocytic naevus or just 'naevus' (but note that there are other types of naevi). Recurrent nevus (persistent nevus) may resemble melanoma (pseudomelanoma) due to irregular scarring, lentiginous melanocytic hyperplasia, basilar keratinocytic hyperpigmentation, nuclear enlargement and prominent nucleoli (J Cutan Pathol 2011;38:503) A melanocytic nevus, more commonly known as a mole, is a dark spot on the skin that can vary in size and is caused by benign proliferations of pigment-producing cells called melanocytes.
