What is junctional dysplastic nevus?
Junctional nevi are the result of a single abnormal melanocyte that begins to proliferate at the dermal epidermal junction, and are often seen clinically as a dark flat nevus. A junctional nevus will typically evolve over time into a compound nevus, which is a nevus with both epidermal and dermal melanocytes.
Is a dysplastic nevus cancerous?
Is it cancer? No. A dysplastic nevus is more likely than a common mole to become cancer, but most do not become cancer.
Is junctional nevus benign?
Junctional nevi are benign melanocytic neoplasms in which nests are seen exclusively in the epidermis, predominantly at the dermoepidermal junction (Figs. 2.4 to 2.6).
What does junctional nevus mean?
Listen to pronunciation. (JUNK-shuh-nul NEE-vus) A type of nevus (mole) found at the junction (border) between the epidermis (outer) and the dermis (inner) layers of the skin. These moles may be colored and slightly raised.
Can dysplastic nevus become melanoma?
Dysplastic nevi and melanoma cancer Although most dysplastic nevi don’t turn into melanoma, having one does increase the risk of developing melanoma cancer in your lifetime. The more dysplastic nevi you have, the higher the risk for melanoma.
Do dysplastic nevi need re-excision?
The only reason for re-excison is because of an association between having multiple dysplastic nevi and melanoma. There is no proof that a single dysplastic nevus will become a malignancy. So the answer is, you can absolutely wait to have the excision after your pregnancy and breast feeding.
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.
How to pronounce dysplastic nevi?
dysplastic nevus Pronunciation: (dis-PLAS-tik NEE-vus) A specific type of nevus (mole) that looks different from a common mole. Dysplastic nevi are mostly flat and often larger than common moles and have borders that are irregular. A dysplastic nevus can contain different colors, which can range from pink to dark brown.
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.
