case_images: The histopathological evaluation revealed paucicellular fibrous proliferation in interlacing fascicles of bland fibroblasts (Figure 4(a), haematoxylin and eosin, original magnification 40x). Few mitotic figures and no atypia were observed (Figure 4(b), haematoxylin and eosin, original magnification 200x). Immunohistochemically, the spindle cells focally stain with smooth muscle actin (Figure 4(c), haematoxylin counterstaining, original magnification 100x).
