Microscopic view (400x) of the tumor of the right upper leg. The histopathological pattern, immunoprofile, and localization of this subcutaneous tumor favor the diagnosis of DFSP.

It was found to be a DFSP in histological research due to proliferation of atypical fusiform mesenchymal cells, with multinuclear giant cells which were sometimes arranged in rosettes (Figure 1).
Microscopic view (400x) of the second tumor of the right upper leg. Based on the morphology, clinical history, and immunoprofile it was diagnosed to be a localization of a high grade sarcoma NOS.

CT examination revealed a large lymph node (Figure 3) without any other evidence of distant disease.
Microscopic view (400x) of the tumor located in a lymph node, diagnosed to be a localization of a high grade sarcoma NOS. It developed as a result of the differentiation of the primary tumor 10 years ago. This was concluded based on the morphology, clinical history, and immunoprofile (vimentin positive) of this tumor.
