The sections show thick collagen bundles in the dermis covered by a flat epidermis with basal hyperpigmentation (dermal scar). This is surrounded by a cellular, poorly demarcated, dermal-based spindle cell lesion with a storiform pattern. There is no significant atypia or mitotic activity. The lesion extends, focally, to the deep margin (block A5) and contains adipose tissue within it (honeycomb pattern). | The sections show thick collagen bundles in the dermis covered by a flat epidermis with basal hyperpigmentation (dermal scar).
