A cutaneous blemish known as an ephelis is a small, benign brown or tan blemish that occurs on sun-exposed skin. The onset of ephelis is influenced by the incriminated individual's genetic makeup and cutaneous subtype. Ephelis is generally spherical, although it has a localised region of hyperpigmentation that varies depending on the amount of sun exposure. Hyperpigmentation of basal keratinocytes and extension of rete ridges are seen in superimposed stratified squamous epithelium, while measurable melanocytes are unaffected. Caf�-au-lait macules, junctional nevus, solar lentigo, melano-acanthoma, melanosis, moles, sun spots, liver spots, and malignant epithelial neoplasms all require segregation. Although sun protection is suggested, the harmless ephelis does not require treatment.
