AC almost always affects the lower lip and only rarely the upper lip, probably because the lower lip is more exposed to the sun. [7] In the unusual cases reported where it affects the upper lip, this may be due to upper lip prominence. [7] The commissures (corners of the mouth) are not usually involved. [2] [6]
Histology slide of a solar lentigo. Differently from the melanotic nevi and the verrucous nevi on the skin, age spots change in color and in shape with time. Wang-Michelitsch and Michelitsch propose a hypothesis inspired by their misrepair-accumulation aging theory [12] for the development of age spots. [13]
In the earlier stages of actinic elastosis, elastic fiber proliferation can be seen in the dermis. As the condition becomes more established, the collagen fibers of the papillary dermis and reticular dermis become increasingly replaced by thickened and curled fibers that form tangled masses and appear basophilic under routine haematoxylin and eosin staining.
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 in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
Actinic keratosis (AK), sometimes called solar keratosis or senile keratosis, [1] [2] is a pre-cancerous [3] area of thick, scaly, or crusty skin. [ 4 ] [ 5 ] Actinic keratosis is a disorder ( -osis ) of epidermal keratinocytes that is induced by ultraviolet (UV) light exposure ( actin- ).
