Lentigo
Pronunciation: len-TY-goh (plural: len-TIJ-in-eez)
A well-demarcated, flat, pigmented macule caused by a localised increase in melanocytes, commonly treated with laser or topical depigmenting agents in cosmetic dermatology.
Full Definition
Lentigo (plural: lentigines) is a benign pigmented lesion distinct from an ephelid (freckle) in that it is not UV-dependent in appearance and represents a true increase in the number of melanocytes at the dermoepidermal junction. In cosmetic contexts, solar lentigines ('age spots') and lentigo simplex are the most commonly treated subtypes. Editors must note the correct plural 'lentigines' (not 'lentigoes' or 'lentigos'), which is a frequent error in consumer-facing copy. 'Lentigo maligna', a form of melanoma in situ, must never be described in the same reductive terms as benign lentigines—this distinction carries medico-legal significance.
Usage
Usage note: Always use the correct plural 'lentigines'. In clinical documents, specify subtype (solar, simplex, lentigo maligna). Do not use 'liver spot' in clinical copy.
