A lentigo (/ l ɛ n ˈ t aɪ ɡ oʊ /) (plural lentigines, / l ɛ n ˈ t ɪ dʒ ɪ n iː z /) is a small pigmented spot on the skin with a clearly defined edge, surrounded by normal-appearing skin. It is a harmless (benign) hyperplasia of melanocytes which is linear in its spread.
Lentigo simplex is the most common form of lentigo. [ 2 ] : 29 A single lesion or multiple lesions (lentigines) may be present at birth or more commonly first develop in early childhood. Lentigo simplex is not induced by sun exposure, and it is not associated with any medical diseases or conditions.
Lentigo maligna is where melanocyte cells have become malignant and grow continuously along the stratum basale of the skin, [1] but have not invaded below the epidermis. [2] Lentigo maligna is not the same as lentigo maligna melanoma, as detailed below. It typically progresses very slowly and can remain in a non-invasive form for years.
The maximum shell length of this species is 100 mm, but more commonly it grows up to 75 mm. [2] As is the case in many strombids, the adult shell of Lentigo lentiginosus is very heavy and thick, with a characteristic deep stromboid notch, and a flared, very thick and posteriorly expanded outer lip.
