What is junctional nevus with moderate atypia?
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.
What is a junctional nevus?
A junctional nevus is a mole that occurs between two layers of skin. This image shows two junctional nevi that appear as uniformly brown small macules, round in shape with smooth regular borders. Color Atlas & Synopsis of Pediatric Dermatology.
How do I get rid of junctional nevus?
Is Removal Possible? Small nevi can be removed by simple surgical excision. The nevus is cut out, and the adjacent skin stitched together leaving a small scar. Removal of a large congenital nevus, however, requires replacement of the affected skin.
Is a junctional nevus benign?
Junctional nevi are benign melanocytic neoplasms in which nests are seen exclusively in the epidermis, predominantly at the dermoepidermal junction (Figs.
Can a nevus be cancerous?
Is it cancer? No. A dysplastic nevus is more likely than a common mole to become cancer, but most do not become cancer.
What does moderately abnormal mole mean?
Atypical moles, also known as dysplastic nevi, are unusual-looking moles that have irregular features under the microscope. Though benign, they are worth more of your attention because individuals with atypical moles are at increased risk for melanoma, a dangerous skin cancer.
Is junctional nevus benign?
Do dysplastic nevi grow?
Dysplastic nevi often grow to larger than ordinary moles, and may have irregular and indistinct borders.
What is dysplastic or atypical nevus?
Atypical moles, also known as dysplastic nevi, are unusual-looking moles that have irregular features under the microscope. Though benign, they are worth more of your attention because individuals with atypical moles are at increased risk for melanoma, a dangerous skin cancer. An atypical mole can occur anywhere on the body.
Should you have an atypical mole removed?
A: Atypical moles should be removed. If a mole has been diagnosed pathologically as atypical, whether moderate or severe, it definitely should be removed – and totally with clear margins. The findings indicate an abnormality that can ultimately progress to a melanoma which can be lethal. An atypical mole is not lethal.
What is severe atypia?
Severe atypia: nuclear enlargement to two times or greater the size of the nuclei of the keratinocytes of the stratum spinosum, prominent nucleoli, abundant granular to dusty (due to fine melanin granules) cytoplasm.
