Non-melanocytic mimics of melanoma: part I: intraepidermal mimics

J Clin Pathol. 2009 Feb;62(2):120-7. doi: 10.1136/jcp.2008.060863. Epub 2008 Oct 17.

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, histological, histochemical and immunohistochemical correlation is vital in distinguishing challenging melanoma cases from their mimics. In this review, the different features of the benign, pre-malignant and malignant intraepidermal non-melanocytic tumours and tumour-like lesions that can closely mimic intraepidermal melanoma (melanoma in situ) are emphasised.
