• tamoxifen-treated mice show a diminished response of melanocyte emigration from the upper regions of hair follicles to the epidermal basal layer 3-5 days after neonatal UV radiation compared to controls

neoplasm
• spontaneous development of malignant melanoma by 300 days of age in all mice
• malignant melanomas have the appearance of nodular lesions and tumors show larger and more pleomorphic nuclei, abundant cytoplasm and numerous multinucleated giant cells and low levels of Ki-67 staining
• two distinct malignant melanoma subtypes are seen: 55% of melanomas are in the deep dermis, separated from the naevus cells above by layers of collagen, while 42% of lesions encompass the subepidermal location of the naevi and appear to be expanded naevi, although cells have morphological features of malignancy
• majority of tumors are located on the back
• mice develop malignant melanoma by 200 days of age after a single neonatal UVB dose
• melanocyte migration from the follicular outer root sheath into the epidermis after neonatal UV radiation is normal

pigmentation
• mice develop dermal melanocyte proliferations that are similar to superficial cogenital naevi
• neonates exhibit a higher number of dermal melanocytes

integument
• naevi are nearly always observed immediately beneath the epidermis in a band-like distribution, reminiscent of naevus cells, above lesions
