Twenty samples of benign pigmented neoplasms of the skin, including 9 intradermal nevi and 11 complex ones, were investigated. Fluorescence in situ hybridization was used to detect the copy number of the RREB1 (6p25), MYB (6q23), and CCND1 (11q13) genes. Analysis of the findings revealed no significant changes characteristic of melanoma in the nevi. However, the authors established that there was a direct correlation between the copy number of the MYB and RREB1 genes and that the amount of the MYB gene most frequently deviated from the normal values. In addition, a relationship was found between the number of MYB gene copies and the depth of the epidermal layer. In cases of an intradermal nevus, the copy numbers of the CCND1 and MYB genes were shown to vary more greatly than in cases of a complex nevus.

Seborrheic keratosis (SK) is a prevalent hyperkeratotic dermatological condition characterized by benign proliferation of epidermal keratinocytes, typically occurring in the middle to advanced stages of life. While the trunk is the primary site for lesions, they can also manifest on the extremities, face, and scalp. Although SK is typically benign, there can be morphological overlap with malignant skin lesions, necessitating meticulous differentiation for an accurate diagnosis.
