=========================================================================

● Part of WHO classification
● Osteoclastic giant cells are present in stroma
● Presence of giant cells does not alter prognosis

Case reports
=========================================================================

● 44 year old and 83 year old women (Diagn Pathol 2010;23:55)
● 46 year old woman (Radiographics 2002;22:691)
● 51 year old woman with pleomorphic carcinoma and prominent osteoclastic giant cells (Pathol Int 2009;59:91)
● Cases with neuroendocrine carcinoma (Pathologica 2008;100:176)

Gross description
=========================================================================

● Often brown due to vascular stroma with hemosiderin

Micro description
=========================================================================

● Giant cells are associated with vascular stroma with extravasated red blood cells and hemosiderin, also chronic inflammatory cells and fibroblasts
● Giant cells have variable size and variable numbers of nuclei
● Similar histologic features in nodal metastases and recurrences (Arch Pathol Lab Med 1986;110:636)
● Carcinoma component may be any type
