Figure 6
Keywords: Melanocytic matricoma, Histopathology-image, Pathology
Sections through melanocytic matricoma show a well-circumscribed dermal tumour which may encroach and erode the overlying epidermis (figure 1). There is heavy melanin deposition. The tumour is made up of basaloid cells with some nuclear pleomorphism and conspicuous mitotic activity. Intermixed with these epithelial cells are a population of dendritic melanocytes (figures 1-4). There is focal “ghost cell” keratinisation (figures 5, 6).
