revealed that OGCs were positive for CD 68, which is a characteristic histiocytic marker of OGC (Fig.

Since canalicular expression of BSEP protein in hepatocytes is mostly maintained, immunohistology
is of limited significance in these cases.
. For collagen type I, type II, and type X immunohistochemistry, sections were incubated for 30 min with 5% normal goat serum, followed by incubation with a 1 : 50 monoclonal mouse anticollagen type I antibody (MAB3391, Clone 5D8-G9, Chemicon, Hofheim, Germany), a 1 : 50 monoclonal mouse anticollagen type II antibody (MAB8887, Clone 6B3, Chemicon), or a 1: 500 monoclonal mouse anticollagen type X antibody (Clone COL-10, C7974, Sigma, Taufkirchen, Germany) for 2h, three washings with PBS, and incubation with a biotin-labelled goat antimouse immunoglobulin for 30 min (Acris, Herford, Germany).
Even postsurgical morphologic diagnosis relying on immunohistology
has no markers allowing a clear-cut distinction between these eosinophilic-appearing tumors .
The diagnosis of ENKL must be based on pathologic immunohistology
. The histopathology of ENKL is characterized by vascular central lesions, where the polymorphous lymphoma cells invade around small bloodvessels or vascular tissue, resulting in vascular obstruction and tissue ischemia and extensive necrosis .
