Colon - Absence of INI1 immunostaining in tumor cells of a colorectal adenocarcinoma while stroma cells and tumor infiltrating lymphocytes show strong positivity.
Colon - Adenocarcinoma of the colon showing strong INI1 immunostaining in tumor and stroma cells.
Colon - Almost complete loss of INI1 immunostaining in tumor cells of a colorectal adenocarcinoma. Tumor infiltrating lymphocytes are INI1 positive.
Soft tissues - Angiosarcoma showing complete lack of INI1 immunostaining in tumor cells. Normal blood vessels and lymphocytes show strong INI1 positivity.
Colon - Colorectal adenocarcinoma showing markedly reduced INI1 immunostaining in a distinct fraction of tumor cell nuclei (mosaic pattern). Stroma cells and lymphocytes show strong INI1 positivity.
Colon - Colorectal adenocarcinoma with strong INI1 immunostaining in tumor cells and tumor associated stroma.
Colon - Complete loss of INI1 immunostaining in tumor cells of a colorectal adenocarcinoma. Tumor infiltrating lymphocytes and stroma cells exhibit strong INI1 positivity.
Bone - Complete loss of INI1 immunostaining in tumor cells of a peripheral neuroectodermal tumor (PNET). Tumor infiltrating lymphocytes show strong INI1 positivity.
Stomach - Gastrointestinal stromal tumor (GIST) with markedly reduced INI1 immunostaining in tumor cells.
Colon - Markedly reduced INI1 immunostaining in a fraction of tumor cells of a colorectal adenocarcinoma (mosaic pattern).
Bone - Peripheral neuroectodermal tumor (PNET) with retained INI1 immunostaining in tumor cells.
Soft tissues - Strong INI1 immunostaining in an angiosarcoma.
