Cytologic Appearances in Invasive Lobular Carcinoma of the Breast

Cytologic diagnosis of lobular carcinoma of the breast

“…11,12 The diagnosis of lobular carcinoma often is hindered by the absence or marginality of these criteria, especially on poorly abundant material.…”

Cytologic Evaluation of Prognostic Markers in Breast Carcinoma

“…Besides helping with the identification of metastatic and nonepithelial malignancies 14,15 and increasing knowledge of uncommon and sometimes cytologically bland variants of carcinoma, [5][6][7] tumor typing provides important prognostic information. Tubular, medullary, mucinous, papillary and secretory carcinomas, which carry better prognoses, 16,17 however, constitute only a small percentage of breast cancers, and tumor size, grade, ER and nodal status remain the more important prognostic indicators in breast cancer.…”

Cytology of Pleomorphic Lobular Carcinoma with Apocrine Cell Differentiation of the Breast

“…[8][9][10][11][12][13][14] According to them, preparations from fine needle aspiration biopsy are of sparse cellularity, and naked bipolar cells are absent. Absence of naked bipolar cells generally indicates malignancy but may not always be important.…”

“…3 Recently we encountered a case of PLC with apocrine differentiation in which the diagnosis by aspiration cytology was apocrine carcinoma. There are several reports describing the cytologic findings of PLC, [8][9][10][11][12][13][14] but to the best of our knowledge those on PLC with apocrine differentiation have not been described. Herein we report cytologic findings of PLC with apocrine differentiation and discuss the distinction from apocrine carcinoma, which is classified as a special type of invasive ductal carcinoma.…”
