What is compound melanocytic 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.
What is a compound nevus with mild atypia?
Mildly dysplastic nevi are nevi that show this tendency to become very much larger than a normal nevus yet there is some central maturation. This can produce a “fried egg” appearance to the nevus. Mildly dysplastic nevi do not show asymmetrical colour variation or irregularity or edge.
What does compound melanocytic nevus mean?
Compound melanocytic nevi are simply a combination of junctional and dermal nevi. Nevomelanocytic nests are located at the DE junction in discrete nests, accompanied by an underlying collection of dermal nevomelanocytes (see the image below).
What is atypical compound melanocytic nevus?
INTRODUCTION. Atypical nevi, also known as dysplastic nevi, are benign acquired melanocytic neoplasms. Atypical nevi share some of the clinical features of melanoma, such as asymmetry, irregular borders, multiple colors, and diameter >5 mm (picture 1A). They occur sporadically or in a familial setting.
What is melanocytic atypia?
Schwarcz, MD Contents Atypical Moles. Atypical melanocytic lesions, which are also called atypical moles or atypical melanocytic hyperlasias, are pigmented moles that contain abnormal cells. These moles are usually benign. However, in some cases, atypical melanocytic lesions can become melanomas.
What is mild atypia?
Mild Atypia: These are very low grade changes within a mole. They often do not require much treatment. They can be observed and watched for future changes. Moderate Atypia: These moles are more atypical than mild atypical moles, but they are still not very concerning.
