Basaloid carcinoma
These low and high magnification photos of the tumor show nests of basaloid cells with peripheral palisading.
The cells of basaloid carcinoma are positive for cytokeratin and negative for neuroendocrine markers. In some
tumors basaloid pattern is mixed with patterns consistent with adenocarcinoma, large cell carcinoma, or squamous
cell carcinoma. The World Health Organization classifies basaloid carcioma under large cell carcinomas.
