Figure 3From: Liposarcoma of the colon presenting as an endoluminal massHistologic 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×).Back to article page
