Squamous Cell Carcinoma of the Breast Report of a Case

Abstract

EPORTED cases of squamous cell carci-R noma of the breast are rare. This is, perhaps, surprising when one considers the ectodermal origin of mammary epithelium.

Fine Needle Aspiration Cytodiagnosis of Primary and Metastatic Squamous Cell Carcinoma of the Breast

“…In most of the cases the diagnosis was made by histologic examination. 1,4,5,7,8,15 In recent years, with increasing use of fine needle aspiration cytology (FNAC) as the first-line investigation in the assessment of palpable breast lesions, it is likely that cytopathologists will more often diagnose this rare carcinoma from an aspirate; small numbers of cases are reported in the recent cytologic literature. 2,3,6,[9][10][11][12][13][14] In four cases of squamous cell carcinomas of the breast, the diagnosis was made from aspirates.…”

Cytodiagnosis of pure primary squamous-cell carcinoma of the breast by fine-needle aspiration cytology

“…Pure primary squamous-cell carcinomas of the breast are extremely rare and in the few cases reported the diagnosis was made by histologic examination. [1][2][3][4][5][6] It is likely that cytopathologists will more often diagnose this rare carcinoma in aspirate material from the breast, especially since fine-needle aspiration cytology (FNAC) continues to become a first line of investigation in the assessment of all types of breast lesions; small numbers of cases reported in the recent cytological literature seem to support this fact. [7][8][9][10][11][12][13][14][15] In this communication the cytohistologic findings in five cases of pure primary squamous-cell carcinomas of the breast are described in which the diagnosis was made from FNAC.…”
