Figure 2
Histological features (H&E) of the excised pleomorphic dermal sarcoma. (A) The tumour extends from the dermis, through the subcutaneous fat plane*, to focally invade galea aponeurotica**. (B) Tumour cells infiltrate among adipocytes in the subcutaneous fat. (C) Tumour cells exhibit pleomorphic, enlarged and irregular nuclei, with prominent nucleoli. Mitotic activity was identified (arrow), including occasional atypical mitotic figures.
