neoplasm

increased cutaneous melanoma incidence ( J:222847 )

• spontaneous development of malignant melanoma by 200 days of age in all mice treated with tamoxifen

• tumors of tamoxifen-treated mice are relatively small, with regular ovoid shape and high levels of Ki-67 staining

• naevi are not seen above dermal malignant melanomas in tamoxifen treated mice, although small nests of melanocytes in a subepidermal location are occasionally seen

• early lesions of tamoxifen treated mice do not show evidence of tumor derivation from the upper dermis and appear to be derived from follicular or other deep dermal precursors

• majority of tumors of tamoxifen treated mice are located on the back

increased incidence of tumors by UV-induction ( J:222847 )

• all mice treated with tamoxifen develop malignant melanoma before 150 days of age after a single neonatal UVB dose

• 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

increased cutaneous melanoma incidence ( J:222847 )

• 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
