Introduction
• Papillary neoplasm (PN) of the breast
• Fine Needle Aspiration Biosy (FNAB)
• PN and FNABPN and FNAB
- It is difficult to determinate their malignancy (Jeffrey and Ljung 1994)- Several other breast lesions may have similar features and may be misclassified as PN by FANB (Kline et al 1986, Naran et al 1988, Bardales et al 1994)
Methods
• Breast tumors diagnosed as “PN” by FNAB at Samsung Medical Center between Oct. 1994 and May 2004
• Retrospective study for 66 patients who underwent surgery - Diagnostic accuracy - Malignancy- Radiologic malignancy and pathologic results
* Including 5 cases of MP+other tumors; 2 atypical ductal hyperplasia (ADH) , 1 non pDCIS, mucinous ca, 1 invasive ductal ca(IDC) † Including 3 cases of SP+other tumors; 2 non pDCIS, 1 IDC
An invasive papillary carcinoma (Lt) and a papilloma with clustered papillary architecture, which are difficult to differentiate malignancy
Conclusions
• When FNAB suggests ‘Papillary Neoplasm’, even if a radiologic benign, surgical excision should be considered because of high possibility of malignant tumor
