- "Breast cytology." Fragment of benign breast tissue consisting of ductal epithelial cells with interspersed myoepithelial cells. Introduction. Furthermore, the number of myoepithelial cells can be helpful in distinguishing between benign proliferative breast disease and carcinoma on fine needle aspiration cytology … The basal cells is myoepithelial. FNAC and myoepithelial cells lose the cytoplasm and become naked nuclei by losing the cytoplasm on cytology7. Solid nests: squamous cells Smears of nipple discharge showed scattered and clustered foam cells. DUCTAL CELLS • Flat sheets • Discernable borders (honeycomb) • Nuclei uniform MYOEPITHELIUM • Small dark bipolar nuclei • Scant cytoplasm • Singly or within epithelium Myoepithelial cells can be seen as naked nuclei as in other lesions or take the form of comma shaped dark nuclei, spindle, epithelioid or plasmacytoid Epithelioid cells with intranuclear inclusion and intracytoplasmic vacuoles gives the characteristic soap bubble appearance (Cancer 2006;108:250) Papillary lesions (intraductal papilloma, etc): We report a case of primary mucinous carcinoma of nasojugal region in a 51-year-old female. Distinction between basaloid neoplasms on fine-needle aspiration cytology is based on the presence or absence of additional features, including a second cell population (eg, myoepithelial cells), an acellular stromal component, and/or cytologic atypia within the basaloid epithelium. The lesional cells are similar to those on cytology. 06/05/2016 5 Abstract. Stain with LMW cytokeratins (e.g., CK7) 2) Outer myoepithelial cell Flat (sometimes barely visible) to plump with abundant clear cytoplasm. FNAC of the breast is a simple, cost-effective, less traumatic, sensitive and a rapid diagnostic method. The luminal cell is epithelial. [15] It is a pure carcinoma composed only of malignant myoepithelial cells; therefore the current case is not myoepithelial carcinoma. In cytology, a cellular smear with a dispersed/discohesive population of cells with round nuclei, coarse chromatin or hyperchromatic chromatin, and prominent nucleoli raises a … (CASE STUDY, Report) by "New Zealand Journal of Medical Laboratory Science"; Health, general Breast cancer Care and treatment Diagnosis Risk factors Cancer Complications and side effects Carcinoma Cytology Usage Grey Zones in Breast Cytology. RESULTS. The epithelial sheets bear scattered myoepithelial cells just out of the plane of focus (arrows). Hammond S, Keyhani-Rofhaga S, OÕToole RV. Smaller, more regular lymphoid cells were seen in the background together with lymphoglandular bodies. Potential diagnostic problems may arise due to morphologic heterogeneity of myoepithelial cell-rich lesions and difficulty in predicting malignancy in FNA specimens. Smears from Breast FNAB cytology does offer many advantages because it is quick, is minimally invasive, causes minimal physical and psychological discomfort, and is acceptable to patients. AIMS AND OBJECTIVE: To study the role of myoepithelial (ME) cells in distinguishing benign, proliferative breast diseases (PBD) and frank malignant breast lesions. (d) The corresponding excisional biopsy shows hypersecretory change in mammary glands with abundant luminal secretions. J Cytol Histol 9: 514. doi: 10.4172/2157-7099.1000514 Page 2 of 5 J Cytol Histol, an open access journal ISSN: 2157-7099 Volume 9 • Issue 4 • 1000514 1. Breast myoepithelioma. In addition, a combination of features not usually seen in benign aspirates may be present. Breast FNAB is a highly specific and sensitive test to accurately diagnose benign and malignant lesions when undertaken by an operator experienced in the biopsy technique and cytopathologists experienced in reporting breast cytology. Fig 4. Citation: Patel MJ, Patel SC (2018) Fine Needle Aspiration Cytology and Cell Block Study of Various Breast Lumps . The cytoplasm of epithelial cells uniformly reacts with antibodies to cytokeratins, such as cytokeratin AE1/3 (Figure 2, A and B), CAM 5.2, or CK7. Myoepithelial carcinoma of the breast (MEC), a lesion composed purely of malignant myoepithelial cells, remains a rarely reported phenomenon. Benign Breast Lobules in Fat: “Respect” the Fat . breast pathology overview of what will be covered regarding female breast ii. cytology and cell block in the diagnosis of different breast lesions and to evaluate the diagnosing utility of cell block with respect to fine needle aspiration cytology by comparing diagnosis of various breast lesions attained with the help of fine needle aspiration cytology and cell block with the histopathological diagnosis given for the same. Breast Lesion Myoepithelial Cell Lobular Carcinoma Invasive Lobular Carcinoma Fine Needle Aspiration Cytology These keywords were added by machine and not by the authors. Breast Cytology Minimally ... myoepithelial cells naked nuclei Apocrine cells CYTOLOGICAL CRITERIA OF MALIGNANCY Loss of cohesiveness Isolated cells with cytoplasm Nuclear pleomorphism Dirty background No naked nuclei . Myoepithelial cells were present in all cases but were scant or absent in small epithelial groups. The key to breast pathology is the myoepithelial cell. Normal myoepithelial cells Bare bipolar nuclei. Modified Giemsa stain. It is a relatively inexpensive test. Myoepithelioma of the breast is very rare, mostly benign tumor which usually contains two different kinds of neoplastic cell growth.It contains a certain amount of myoepithelial cells in a ‘spindle shape‘, in addition to clusters of neoplastic epithelial cells.. C3: Atypia probably benign. [15] It is a pure carcinoma composed only of malignant myoepithelial cells; therefore the current case is not myoepithelial carcinoma. Myoepithelial carcinoma is listed in one category of WHO 2012 blue book. Myoepithelial cells are not typically present on the stalks; May have nuclear clearing; Compact columnar Lined by uniform population of often columnar cells; Fine, evenly distributed chromatin; Transitional cell Resembles low grade transitional cell carcinoma ; High grade cytology rare; Mitotic figures may be seen Breast Cytology. (c) The cells here are monotonous, with prominent nucleoli; cytoplasm is foamy and delicate (TP). Lesions that contain abundant myoepithelial cells may present as a diagnostic challenge in fine-needle aspiration (FNA) specimens. iv. myoepithelial cells or benign ductal cells . Stains for myoepithelial cells (see below) should be employed as part of a panel or cocktail with at least one nuclear andone cytoplasmic stain (e.g., p63 and SMMHC). This process is experimental and the keywords may be updated as the learning algorithm improves. Your online resource for virtual pathology training. Aims: One of the limitations of fine needle aspiration biopsy (FNAB) of the breast is in distinguishing invasive carcinoma (IDC) from ductal carcinoma in situ (DCIS). The myoepithelial cells help ‘ squeeze ‘ the contents ( milk) of the secretory cells into the duct. Lactating breast Breast FNA from a pregnant or lactating woman often poses a diagnostic challenge. The presence and quantity of myoepithelial cells, bipolar naked nuclei in the background, and ductal cell architecture were the only consistently useful cytologic features in distinguishing breast lesions with a … Occasional smaller dark cells with less cytoplasm are seen in the lower left of the image. The heterogeneity with which myoepithelial cells may present on cytology can therefore complicate the diagnostic process for myoepithelial carcinoma even fur- ther, obviating a need to ... Infiltrating myoepithelial carcinoma of the breast, a case report and cytologic-histologic correlation . Suspicious of carcinoma •3 of 4 malignant features present ... Liquid-based cytology in breast FNA •Designed to improve the conventional cytological preparations by avoiding limiting factors: –Obscuring material –Air-dried artifacts (d, H&E) FNAC of eight breast masses diagnosed cytologically as BSCTs was followed by wide excision biopsy. C.H. findings, we advocate that anti-p63 antibodies may be used to identify myoepithelial cells as well as to overcome the cytomorphologic distortion of myoepithelial cells in FNABs of the breast. Adenomyoepithelioma of the breast - A (usually) benign tumor of the breast composed of Myoepithelial and Adeno (glandular) cells. Myoepithelioma of the Breast- A usually benign or exceedingly rare malignant tumor of the breast which mimics IDC but with cells resembling adenoid cysts. Cytology of Fibrocystic disease showing benign ductal cells with myoepithelial cells and foamy macrophages (Leishman, x 400x). Stain with Actin, calponin, SMMHC, p63, CK5/6, S100 Myoepithelial cells (sometimes referred to as myoepithelium) are cells usually found in glandular epithelium as a thin layer above the basement membrane but generally beneath the luminal cells. The aspirate was reported to the breast surgeon in the one-stop clinic as being malignant, C5, with appearances suggestive of a Breast spindle cell tumours (BSCTs), although rare, represent a heterogeneous group with different treatment modalities. Figure 5: 10x P63 Immunohistochemistry (IHC) highlights the myoepithelial cells. • Cytology CYTOLOGY OF NORMAL BREAST STRUCTURES • Ductal cells • Myoepithelial cells • Acini • Stroma . A benign gland has two cell layers - myoepithelial and epithelial. BACKGROUND. Two cell layers: 1) Inner Epithelial cell Cuboidal to columnar cells with eosinophilic cytoplasm and oval nuclei.
