ABSTRACT
This chapter presents the case study of a 49-year-old woman. A 49-year-old woman presents with a 20-year history of a nodule on her face, which she felt had slowly increased in size over the years. She has a dome-shaped, firm, flesh-coloured nodule lateral to her left eye. There is no surface change felt over the nodule, no telangiectasia and no tenderness. Full skin examination does not reveal any other lesions of note. This nodule is a benign intradermal naevus, otherwise known as a ‘mole’. A naevus from the word ‘nest’ is a benign proliferation of cells, as in this case melanocytes. Melanocytic naevi are very common and are usually multiple. Naevi may be macular or papular/nodular, they vary in colour from pink or flesh-coloured to dark brown or black. Finally, the junctional component of the naevus may resolve leaving an intradermal naevus, as in this patient. These moles often protrude from the skin surface and are flesh-coloured or slightly pigmented.
