Figure 4. From: Molecular Aspects of Melanocytic Dysplastic Nevi.

Immunohistochemical staining of MMR proteins in melanocytic dysplastic nevi (MDN). A: hMLH1 expression in the normal epidermis. Note the nuclear expression pattern (arrow): B: hMSH2 expression in MDN. Positively (arrow) and negatively (arrowhead) stained cells are observed in both MDN and CMM.

Figure 3. From: Molecular Aspects of Melanocytic Dysplastic Nevi.

Genetic changes in melanocytic dysplastic nevi. Left: Microsatellite instability (MSI), with the arrowhead indicating the appearance of a novel band in the tumor (T) DNA as compared to DNA from the normal tissues (N). Right: Loss of heterozygosity (LOH) in the tumor DNA, with the arrowhead indicating loss of upper allele in the tumor.
