RT Journal Article SR Electronic T1 Non-melanocytic mimics of melanoma: Part I: intraepidermal mimics JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 120 OP 127 DO 10.1136/jcp.2008.060863 VO 62 IS 2 A1 Kamil, Z S A1 Tong, L C B A1 Habeeb, A Al A1 Ghazarian, D YR 2009 UL http://jcp.bmj.com/content/62/2/120.abstract AB 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.
