BACKGROUND :- Lung cancer is the leading cause of cancer-related mortality over word wide, Although pathological diagnosis lung carcinoma limited as only small specimen available for diagnosis.the availability targeted therapies has created a need precise subtyping non-small cell . Several recent studies have demonstrated that use Immunohistochemical markers can be helpful in differentiating sq...

BACKGROUND Pulmonary enteric adenocarcinoma (PEAC), a rare type of non-small cell lung cancer, has similar histological and immunohistochemical morphology to colorectal adenocarcinoma. Cadherin-17 (CDH17) and SATB homeobox 2 (SATB2) immunoexpression have recently been demonstrated in colorectal adenocarcinoma. In this study, we evaluated the value of CDH17 and SATB2 in the diagnosis of pulmonar...

Materials and Methods Formalin-fixed paraffin-embedded lung SqCC (n=137) and LADC (n=60) tissue microarrays were acquired. DSG3/p40 + Napsin A double stain cocktail (Biocare Medical, Concord, CA), TTF-1 [SPT24] and TTF-1 [8G7G3/1] antibody titers were optimized for IHC. SPT24 was optimally titered at 1:1200. The double stain antibody cocktail was detected by using a polymer double stain detecti...

Ovarian seromucinous borderline tumors (SMBTs) are rare. They architecturally resemble serous borderline tumors but are much more frequently associated with endometriosis. The coexistence of other tumors with seromucinous tumors is also extremely rare. Here, we report an unusual combination of bilateral ovarian SMBT and clear cell carcinoma associated with polypoid endometriosis of the colon, i...
