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]

Squamous-cell cancers of the lip and ears have high rates of local recurrence and distant metastasis. [27] In a recent study, it has also been shown that the deletion or severe down-regulation of a gene titled Tpl2 (tumor progression locus 2) may be involved in the progression of normal keratinocytes into becoming squamous-cell carcinoma.
