柱状细胞病变(columnar cell lesions,CCL)常常与低级别导管原位癌(ductal carcinoma in situ,DCIS)并存于同一乳腺,具有相似的形态学和免疫组化染色特征,提示CCL可能是低级别DCIS/浸润性癌的前驱病变。作者总结了18例患者的55个CCL的形态学和免疫组化染色特征,同时运用比较基?
Columnar cell lesions (CCL) often coexist with low-grade ductal carcinoma in situ (DCIS) in the same breast and have similar morphological and immunohistochemical characteristics, suggesting that CCL may be a low-level DCIS / Invasive disease of the precursor. The authors summarize the morphologic and immunohistochemical staining of 55 CCLs in 18 patients, using a comparative base?
