Lentigo is defined as a small spot on the skin that is pigmented, its edges are clearly defined. This spot is surrounded by normal-appearing skin. It is benign in nature and is due to the overproduction (hyperplasia or increased number) of melanocytes (pigment cells). Owing to their brown-black color, they are also called liver spots. Lentigine is another name for lentigo, contributed by its small, lentil-like appearance.
Not quite. Despite both of them have a hyperplasia of melanocytes, only freckles darken with increased sun exposure. Lentigo remains of the same pigment and does not darken, regardless of sun exposure.
Intertrigo is the hyperpigmentation of the skin secondary to a fungal infection. Intertrigo, unlike lentigo, causes itching and foul odour.
No, Lentigo does not itch or cause any symptoms. It is merely a darkening of the skin pigment.
Lentigo (plural: lentigines) is of different types, based on its cause and site of occurrence.
It is the most common type and can be seen congenitally on the trunk, arms, and legs. These spots can, however, disappear with time.
It is caused by ultraviolet radiation exposure. Fair skinned people, old people, people who work a lot in the sun, and those who use tanning beds may develop solar lentigo.
These can be seen in light-skinned people after a sunburn.
PUVA Lentigo starts after psoralen and ultraviolet A (PUVA) therapy, which is used to treat skin conditions like eczema and psoriasis.
Tanning beds are an artificial way of making skin look nice and tanned despite lack of sun exposure.
Radiation lentigo occurs in areas of skin that have been exposed to radiation – for example, from cancer treatment.
Since lentigo can be confused with a malignant condition, a doctor will take a biopsy to confirm the diagnosis. The sample will be sent to a lab for testing.
Lentigo is mostly linked with increased UV ray exposure. However, if you have a fair complexion or use tanning beds regularly, you are more likely to develop lentigo.
Lentigo is a gender-neutral skin condition and can occur in almost all ages. However, like most detrimental changes, are evident more in older people. Men and women can equally get lentigo but women are more likely to seek consultation and treatment.
Bleaching creams, chemical peelers, cryotherapy and laser treatment are some of the options to treat lentigo.
