Epithelial-myoepithelial carcinoma (EMCa) is a rare neoplasm that most frequently afflicts the parotid gland. Histologically, a dual layer of inner, luminal epithelial cells and outer myoepithelial cells with associated background hyalinization characterize these tumors. Several variants of EMCa hav Epithelial / myoepithelial carcinoma The tumor is composed of two cell types which form duct-like structures: ductal cells (inner layer), clear myoepithelial cells (outer layer). They can be distinguished by immunocytochemistry: the former are pan-keratin positive, the latter are S-100 positive

Going beyond basaloid neoplasm: fine needle aspiration cytology of epithelial-myoepithelial carcinoma of the parotid gland. Diagn Cytopathol Epithelial‐myoepithelial carcinoma (EMC) is a rare salivary gland malignancy with variable cytologic findings. Its rarity, variable morphologic findings, and similarities with more common salivary gland entities make it a difficult cytologic diagnosis. As the name signifies, the key feature of this tumor is presence of an epithelial and myoepithelial component One of the major challenges in salivary gland cytology is the accurate separation of biphasic basaloid neoplasms such as pleomorphic adenoma, basal cell neoplasms (adenoma and adenocarcinoma), epithelial-myoepithelial carcinoma, and adenoid cystic carcinoma. 6 The inability to separate these tumor types with greater accuracy preoperatively is. BACKGROUND. Epithelial myoepithelial carcinoma (EMC) was initially described by Donath et al. 1 and was previously referred to with various terminologies such as adeno-myoepithelioma, clear cell adenoma, or carcinoma. EMC is a rare biphasic tumour of the salivary gland with two cell types: an inner layer of duct lining cells and an outer layer of clear cells, which typically form double.

BACKGROUND. Pleomorphic adenomas are easily identified on cytology, because of their characteristic biphasic pattern comprising of epithelial/myoepithelial cells and fibromyxochondroid stroma. Fine needle aspiration cytology (FNAC) is a highly accurate tool for the diagnosis of pleomorphic adenoma, with a reported reliability of 80-95%.[1 2] However, even this common salivary gland neoplasm. We present a case of a 72-year-old man with a parotid mass which was initially diagnosed as a pleomorphic adenoma. Intraoperatively, the tumour was found to be invading the facial nerve. It was later found to be an epithelial-myoepithelial carcinoma, a rare salivary gland tumour. Despite invasion of the facial nerve, function of the nerve remained intact Myoepithelial carcinoma (malignant myoepithelioma) of the breast is a rare tumor, for which only a limited number of reports have been published. Most of the reports emphasized diagnosis and pathology but not biological behavior and treatment. We report a 61-year-old patient with breast myoepithelial carcinoma who developed locoregional and distant metastases and received many chemotherapy.

Two cases reported as benign on FNAC (Category IVa), were diagnosed as pleomorphic adenoma (PA) with foci of epithelial myoepithelial carcinoma (EMC) [Figure 2a and b] and atypical PA, respectively, on histopathology.

This patient presented to haematology following an abnormal bleeding episode with von Willebrand factor Ristocetin cofactor (VWF:RCo) <5% and VWF:Ag 13%. He was diagnosed with AvWD Of the 34 cases reported as pleomorphic adenoma on cytology, 3 cases turned out to be malignant - 2 cases of adenoid cystic carcinoma a and b and 1 case of intermediate grade mucoepidermoid carcinoma a, b, c (false negative for malignancy). On cytology, a total of six cases were reported to have atypical features, uncertain malignant. Among the 6 malignant tumors on surgical resections, there were 3 epithelial-myoepithelial carcinomas, 1 myoepithelial carcinoma, 1 basal cell adenocarcinoma and 1 adenoid cystic carcinoma. Conclusions: Although 14 of the 20 (70%) cases were benign neoplasms, a substantial amount of cases (30%) were malignant salivary gland neoplasms
In a retrospective review of cytology files of a head and neck referral center from 1990 to 2005, the false positive and false negative interpretations on fine needle aspiration (FNA) of salivary lesions were retrieved.
