“…The majority of our cases (85%) showed epidermal effacement with either a junctional or compound melanocytic proliferation, a pattern most commonly illustrated in prior publications, [1][2][3][4][6][7][8][9][10][11] and often showing pagetoid upward migration of melanocytes. In our series, it was this histologic pattern that showed pagetoid spread in 13% of cases (as opposed to 1% of cases of recurrent nevi with retiform epidermis).…”

“…1,2 Recognition of this phenomenon is important as some cases may resemble melanoma (pseudomelanoma). 3,4 We have also observed that some cases of recurrent nevi had histologic overlap with regression in malignant melanoma. In addition, most large studies predate the introduction of the dysplastic nevus concept, and available data on recurrence following removal of dysplastic nevus removal is sparse.…”

“…For the original nevus and recurrent pigmented macule the ratio of stained epidermal area to measured epidermal area and staining intensity were determined by a computed image analysis method. 15 Each process (i.e., sectioning, staining, and digital image taking) was performed simultaneously on the biopsy specimens obtained from all patients before and after treatment. The stained area was measured under constant magnification (Â 200).…”
