A benign (not cancer) growth on the skin that is formed by a cluster of melanocytes (cells that make a substance called melanin, which gives color to skin and eyes). Cases of malignant melanoma arising from an intradermal nevus have rarely been reported. The Junctional Melanocytic mole is a very common nevus and comes in childhood or . Intradermal nevi ( IDN) are first and foremost defined by their clinical morphology as either raised dome shaped lesions or as sessile mamillated lesions. A case of malignant melanoma apparently arising from the lower portion of a preexisting intradermal hairy nevus is presented. Although there are many types of melanocytic naevi, this chapter focuses on the most common melanocytic naevi, often referred to as 'moles', which are the acquired melanocytic naevi and dermal melanocytic naevi. These are generally small, symmetric, and well-circumscribed lesions, averaging 3.5 mm in diameter. Hence, there is no need to remove a sebaceous nevus for cancer prophylaxis (avoidance of malignant tumors). Dermal nevi are brown or black, but may become lighter or flesh-colored with time. Estimating the attributable fraction for melanoma: a meta-analysis of pigmentary characteristics and freckling. They can be photographed and followed for evidence of change or growth prior to consideration of biopsy or treatment. How is a nevus diagnosed? Eyelid nevi are benign tumors.

A melanocytic nevus (also known as "nevocytic nevus") is a type of lesion that contains nevus cells (a type of melanocyte).Some sources equate the term mole with "melanocytic nevus". Histopathologically, melanoma cells developed upward from the nest of the intradermal nevus and no junctional activity was shown. Large eyelid nevi can be a cosmetic problem that can be repaired by ophthalmic plastic surgery. Lesions vary in size from a few millimeters to a centimeter. The skin lesion affecting individuals with Schimmelpenning syndrome is called sebaceous nevus because it . This can be avoided by having a full thickness excision.

A papule, plaque or nodule with a pedunculated, papillomatous (Unna naevus) or smooth surface (Miescher naevus). This is why the melanocytes (the cells that produce dark brown to black pigment) are not visible in the lesion.
