Moles are a member of the family of skin lesions known as nevi (singular "nevus"), occurring commonly in humans. [3] [4] Some sources equate the term "mole" with "melanocytic nevus", [2] but there are also sources that equate the term "mole" with any nevus form. [3]
In 1992, the NIH recommended that the term "dysplastic nevus" be avoided in favor of the term "atypical mole". [1] An atypical mole may also be referred to as an atypical melanocytic nevus, [2] atypical nevus, B-K mole, Clark's nevus, dysplastic melanocytic nevus, or nevus with architectural disorder. [3] Dysplastic nevi often grow to larger ...
The features include: 1) two or more clinically atypical nevi, 2) more than 100 nevi in patients between 20 and 50 years of age, 3) more than 50 nevi in patients under 20 years of age or more than 50 years of age, 4) more than one nevus in buttocks or instep, 5) nevi on the anterior scalp, 6) one or more pigmented lesions in the iris.
Dysplastic nevus (atypical mole, atypical nevus, B-K mole, Clark's nevus, dysplastic melanocytic nevus, nevus with architectural disorder) Dysplastic nevus syndrome (B-K mole syndrome, familial atypical multiple mole–melanoma syndrome, familial melanoma syndrome) Ephelis (freckle) Epithelioid blue nevus; Generalized lentiginosis
Spitz nevus is the medical name for a benign mole. They share a similar appearance with other moles, some that are cancerous. Learn more here. Skip to main content. 24/7 Help. For premium support ...
Atypical (dysplastic) nevus: This type of nevus must be diagnosed based on histological features. Clinically, atypical nevi are characterized by variable pigmentation and irregular borders. [5] Becker's nevus; Blue nevus (rarely congenital): A classic blue nevus is usually smaller than 1 cm, flat, and blue-black in color. [6] Hori's nevus
People with dysplastic nevus syndrome, also known as familial atypical multiple mole melanoma, are at increased risk for the development of melanoma. [21] Having more than 50 moles indicates an increased risk of melanoma. A weakened immune system makes cancer development easier due to the body's weakened ability to fight cancer cells. [18]
A related category of melanocytic proliferation is superficial atypical melanocytic proliferations of uncertain significance (SAMPUS). This category, unlike MELTUMP, which implies as yet undetermined potential for metastases even after complete excision, signifies lesions without metastatic potential at time of excision but with potential to ...
