What does it mean to have a compound nevus?
Listen to pronunciation. (KOM-pownd NEE-vus) A type of mole formed by groups of nevus cells found in the epidermis and dermis (the two main layers of tissue that make up the skin).
Is a nevus benign or malignant?
Acquired melanocytic nevi are considered benign neoplasms. In contrast, congenital melanocytic nevi are perhaps best interpreted as congenital malformations.
What causes compound nevus?
sun damage, especially for those with fairer skin. immunosuppressive treatments, such as those used in cancer, which can cause more moles to develop. genetic factors, such as your parents having a lot of moles, which makes it more likely that you will have them as too.
Is compound melanocytic nevus benign?
Typically they are light tan to dark brown, dome shaped papules that are 1-10 mm in diameter. Compound Nevi are benign proliferations of melanocytes at the epidermal-dermal junction.
Can a nevus become cancerous?
No. A dysplastic nevus is more likely than a common mole to become cancer, but most do not become cancer.
What is compound nevus with architectural disorder?
The architectural disorder includes asymmetry, subepidermal fibroplasia, and a distorted rete ridge pattern with bridging between adjacent rete rides (see the image below). Compound lesions have extension of the junctional component beyond the dermal nests of melanocytes, referred to as shouldering.
Can nevus be removed?
Small- and medium-sized nevi are generally harmless but can be removed for aesthetic reasons. Removal of a small nevus consists of a simple excision, cutting out the affected area and stitching the surrounding skin back together. Removing a large nevus is a much more daunting process.
Does a nevus go away?
Congenital melanocytic nevi do not go away with time. Some congenital melanocytic nevi may get lighter in color over the first few years of life.
Can you have melanoma for years and not know?
How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.
Can a compound nevus turn into melanoma?
Yes — but most dysplastic nevi do not turn into melanoma. Most types of atypical moles remain stable over time. Patients with five or more dysplastic nevi are 10 times more likely to develop melanoma than individuals with no atypical moles.
Does compound nevus grow?
A junctional nevus will typically evolve over time into a compound nevus, which is a nevus with both epidermal and dermal melanocytes. Compound nevi become elevated and usually are more pale. Junctional nevi will typically grow to be 3 or 4 mm across, stop growing sideways, and begin to evolve into a compound nevus.
