What is Lentiginous compound nevus with moderate atypia?
Background: Atypical lentiginous nevus (of the elderly) is a peculiar form of dysplastic nevus. Clinically, this condition can resemble malignant melanoma and histologically, it has a lentiginous pattern with variable degrees of atypia and an absence of dermal nests.
Should moderate dysplastic nevus be removed?
Most dermatologists usually recommend that all patients with these severely dysplastic moles have them removed with a margin (0.5 cm-about a quarter inch) of clinically normal skin. Also many dermatologists recommend removing “moderate dysplasia” moles, if the biopsy didn’t get all of it.
Is compound dysplastic nevus cancer?
A dysplastic nevus may develop into melanoma (a type of skin cancer), and the more dysplastic nevi a person has, the higher the risk of melanoma. A dysplastic nevus is sometimes called an atypical mole.
What does moderate atypia mean?
Moderate Atypia: These moles are more atypical than mild atypical moles, but they are still not very concerning. Depending on some other factors in the biopsy report, these can sometimes be left alone and monitored clinically.
Should a moderately atypical mole be removed?
If the biopsy shows a mildly or moderately atypical mole, and it has been removed fully, no further treatment is needed. Moles that are severely atypical under the microscope may need a slightly wider surgery to ensure that they do not grow back.
What is a Lentiginous compound nevus?
The term lentiginous junctional nevus is used for junctional nevi in which the epidermis has lentigo-like features with elongated and pigmented epidermal rete ridges. In lentiginous nevi, there is typically a proliferation of solitary units and nests.
What is moderately dysplastic compound nevus?
Dysplastic nevi are categorized as mild, moderate, or severe. Remember, a dysplastic nevus is a mole that exists in the spectrum between a benign mole and melanoma. A mildly dysplastic nevus is closer on that spectrum to a benign mole, whereas a severely dysplastic nevus is closer to a melanoma.
Is dysplastic nevus with moderate atypia cancer?
A dysplastic nevus is a mole that exists in the spectrum between a benign mole and melanoma. When looked at with a microscope, the cells of a dysplastic nevus have atypical features and growth pattern, but not to the degree of being cancerous.
Do moderate atypical moles need to be removed?
About 1 in 10 people develop atypical moles during their lifetime. These moles are not cancerous, and need not be removed if they are not changing. Instead, atypical moles can be a sign of an increased risk for melanoma skin cancer.
What does moderately dysplastic mean?
Is atypical nevi cancerous?
Atypical or dysplastic nevi are not skin cancers, and often do not become melanoma, although having them appears to increase your risk of developing melanoma, an aggressive and potentially deadly form of skin cancer.
What is a lentiginous nevus?
Speckled lentiginous nevus is a patch of hyperpigmentation that can be seen on any area of the body. This patch contains a variable number of darkly pigmented macules and papules. Some authorities believe that speckled lentiginous nevus is a subtype of congenital melanocytic nevus.
What is moderately dysplastic nevus?
What is melanocytic nevus and how to treat it?
Melanocytic nevi are benign neoplasms or hamartomas composed of melanocytes, the pigment-producing cells that constitutively colonize the epidermis. Melanocytes are derived from the neural crest and migrate during embryogenesis to selected ectodermal sites (primarily the skin and the CNS), but also to the eyes and the ears.
What is lentiginous hyperplasia?
What is lentiginous hyperplasia? The term ‘atypical lentiginous hyperplasia’ is being increasingly used by pathologists to describe lentiginous hyperplasia where melanocytes display some cytological atypia with minimal nesting of melanocytes and without florid pagetoid spread. What is a compound melanocytic proliferation?
Should dysplastic nevus be removed?
The best way to treat a dysplastic nevus depends on its category. Mildly dysplastic nevi do not need further treatment, while severely dysplastic nevi should be surgically removed. There is less consensus among leading physicians on the best treatment option for moderately dysplastic nevi.
Is compound nevus cancerous?
A compound nevus is a non-cancerous type of growth made up of melanocytes. Compound nevi are usually seen in individuals of lighter skin complexion and can be found anywhere on the body. Most compound nevi are called acquired because they develop in children or young adults. A nevus that develops shortly after birth is called a congenital nevus.
