Figure 1: (a) Involvement of left dorsum of nose in the form of well defined, mildly erythematous plaque with slightly depressed centre. (b) Dermoscopy showing a central white scar-like patch with marginal hyperpigmentation, faint erythema and few linear telangiectatic vessels (Heine Delta 20T, polarized,×10). (c) Involvement of dermis in form of spindle cell proliferation with collagen trapping (Black arrow, H and E,×400). (d) Spindle cell nucleus tapered at both ends with indistinct cytoplasm intermingled with histiocytes containing vesicular nuclei (H and E,×1000)
