Histologic examination of the primary tumour. The tumour was mainly located in the submucosal layer. Cells with marked atypia in the centre of the field (hematoxylin-eosin, original magnification 10×); (b) Low power view of a sclerotic area with pleomorphic spindle shaped cells with marked atypia. In the centre of the field there is a multinucleated giant cell and some atypical, hypercromatic lipoblasts (hematoxylin-eosin, original magnification 20×); (c) High power view of a multinucleated giant lipoblast with floret-like features. This kind of cells is very similar to those found in the so called "malignant fibrous histiocytoma" (hematoxylin-eosin, original magnification 40×); (d) High power photomicrograph showing a lipoblast with a pleomorphic, enlarged, hypercromatic nucleus, and numerous cytoplasmic vacuoles containing fat, positive for S-100 (S-100 immunoistochemical stain, original magnification 40×).
