Its initial focus is to identify those antibodies that are the best performers in
immunohistochemistry on formalin-fixed paraffin-embedded tissues.
Unlike SFTs, desmoid tumor shows reactive actin and nonreactive CD34 on
immunohistochemistry tests.[15] Hematoma of rectus sheath cannot be accurately diagnosed solely based on symptoms and signs (such as anorexia, nausea, fever, and tachycardia) due to lack of specificity.
The results of
immunohistochemistry and CISH are summarized in Figure 1; 12 of 44 tumors (27.3%) expressed ER, and 3 of 44 tumors (6.8%) expressed PR.
The scoring of HER-2/neu was done according to American Society of Clinical Oncology and College of American Pathologists (ASCO/CAP) guidelines.13 For the overexpression of the protein HER-2/neu,
immunohistochemistry was done on selected representative slides of the tumor.
This evaluation of HER-2/neu gene amplification by FISH is important because only those cases that are grade 3+ and 2+ by
immunohistochemistry, that are positive for FISH amplification present evidence of more benefit of adding trastuzumab to the chemotherapy regimen.
Immunohistochemistry was done in 44 out of 47 cases in total.
Damavandy's retrospective review of 49 cases may seem small, he said, but it is "far and away the biggest cohort that exists, and the only substantial cohort with
immunohistochemistry staining of CK-7." The 5-year follow-up is also a strength of the study.

We reported an unusual case of rPNET confirmed by morphology and
immunohistochemistry. rPNET is an extremely rare entity with aggressive biology behaviour and poor prognosis.
Of the recent biomarker tests approved by the FDA (as of October 2013), 5 out of 18 are tissue based and all involve
immunohistochemistry (ER, PR, Her2, p63, c-kit) (REF2).
Toxoplasma gondii parasites were identified with
immunohistochemistry in all examined organs: lung, heart, liver, kidney, and spleen.

We took 5 mm punch biopsy from nevus for histopathology and
immunohistochemistry for HMB45 antigen before and after treatment.
