My microscopic description is 8x6x1mm in situ there is proliferation of atypical melanocytes arranged as solitary units and in nest at the dermal epidermal junction with scattered atypical melanocytes throughout the upper reaches of the epidermis. Where nests are present, they tend to confluence. The dermis contains a scattered inflammatory cell infiltrate with occasional bland appearing melanocytes and melanophages, though no no diagnostic invasive disease is seen. These findings are those of melanoma in situ arising in the background of a dysplastic Nevis. The lateral margin is involved. Re excision recommended in order to ensure complete removal then it say clinical diagnosis Nevius mm 8x6x1mmtoto3p1boa
