NON MELANOCYTIC MIMICS OF MELANOMA Part-I: INTRAEPIDERMAL MIMICS
Abstract
Melanoma comprises a wide range of cytological and architectural features histopathologically and hence can mimic many benign and malignant lesions of epithelial, mesenchymal and hematopoietic cell lines of differentiation. Therefore, analysis and close clinical, histologic, histochemical and immunohistochemical correlation is vital in distinguishing challenging melanoma cases from their mimics. In this review, we emphasize the different features of the benign, pre-malignant and malignant intraepidermal non-melanocytic tumors and tumor-like lesions that can closely mimic intraepidermal melanoma (melanoma in-situ).
