Abstract PDF: Fine needle aspiration cytology is considered as a useful diagnostic procedure in management of patients with breast lesions. This study was undertaken to evaluate the scoring system of Masood in the interpretation of breast aspirates, to establish the most useful cytologic criteria for the diagnosis of breast lesions, and to subclassify the benign breast diseases. To assess the feasibility of a cytologic grading system, 57 cases of benign breast disease, 61 cases of malignant breast disease were studied, respectively. The aspirates were evaluated for the cellular arrangement, the degree of cellular pleomorphism and anisonucleosis, and the presence of myoepithelial cells and nuceoli. Values ranging from 1 to 4 were assigned to each criterion and the sum of the individual values was made for each case. The presence of stroma, apocrine metaplasia, foamy histiocytes and inflammatory cells, background of the smear, and cellularity were also evaluated. Cut-off value of the scoring system of Masood between benign and malignant lesion was 15. Among the cytologic criteria, cellular arrangement, presence of myoepithelial cells, nucleoli, and stroma, status of chromatin pattern, and background of smear were useful criteria in the differentiation between benign and malignant lesions. Application of the scoring system of Masood does not always make the accurate diagnosis and the subclassification of benign breast disease.

Case Reports

Fine Needle Aspiration Cytology of Metastatic Melanoma in the Breast: A Case Report.: Young Lyun Oh, Young Hyeh Ko; Korean J Cytopathol. 1998;9(1):111-116.

Abstract PDF: Although the characteristic cytologic features of melanoma have been well described, the diagnosis of metastatic melanoma by fine needle aspiration cytology (FNAC) may be difficult in the case of amelanotic melanoma and in the absence of awareness of clinical history. Furthermore, when the breast is the site of initial presentation, it could simulate a primary breast carcinoma leading to misdiagnosis. The recognition of metastatic malignant melanoma in FNAC material is essential to avoid an unnecessary mastectomy and to ensure appropriate chemotherapy. We experienced a case of metastatic melanoma of breast which presented as solitary breast mass in a 56-year-old woman. She had a history of surgical excision of right foot for melanoma one year ago. The cytologic smears were composed of noncohesive epithelioid cells with round or eccentric nuclei, bi-or multi-nucleation, prominent nucleoli, fine chromatin, and intranuclear inclusions. The cytoplasm of tumor cells had scanty melanin pigment but were diffusely positive for S-100 protein.

Fine Needle Aspiration Cytology of Solid Papillary Carcinoma of the Breast: Report of a case associated with mucinous carcinoma.: Hee Kyung Kim, Dong Won Kim, So Young Jin, Dong Wha Lee; Korean J Cytopathol. 2001;12(2):127-130.

Abstract PDF: Solid papillary carcinoma of the breast is a distinctive form of intraductal papillary carcinoma frequently associated with both mucinous carcinoma and infiltrating ductal carcinoma, not otherwise specific. To our knowledge, this case is the first description of the cytologic aspects of solid papillary carcinoma of the breast in the Korean literature. We experienced a case of solid papillary carcinoma of the right breast diagnosed by fine needle aspiration cytology(FNAC) in a 70-year-old female. FNAC from the right breast showed high cellularity consisting of mostly tight clusters of tumor cells and a few scattered tumor cells. The nuclei were monotonously round to oval in shape with inconspicuous nucleoli. The cytoplasm was abundant and finely granular. Scant amount of mucinous material was present on the background. The diagnosis was confirmed histologically and immunohistochemically.
