Primary epithelial myoepithelial carcinoma of lung is a rare entity and is thought to arise from the submucosal bronchial glands distributed throughout the lower respiratory tract. Because of the rarity of this tumor, we describe one case of epithelial myoepithelial carcinoma arising in the bronchus intermedius and presenting as an endobronchial mass. A 57-year-old male patient presented with a...
OBJECTIVES The aim of this study was to present a rare neoplasm, Primary myoepithelial carcinoma arising from the palate, and to review its diagnostic criteria, pathologic and clinical characteristics, treatment options and prognosis. CLINICAL PRESENTATION AND INTERVENTION Myoepitheliomas are tumors arising from myoepithelial cells mainly or exclusively. Myoepitheliomas mostly occur in saliva...
Epithelial myoepthial carcinoma (EMEC) is rare, low grad tumor with epithelial and myoepithelial components frequent local recurrence, also called glycogen rich adenoma (clear cell pattern), myoepithelioma (spindle plamocytiod patterns), (if only differentiation marked cytologic atypia). Occurs most frequently in the major salivary glands accounts for approximately 1% of all gland neoplasms tha...
Increasing emphasis has been placed on the role of myoepithelial cells, the contractile components of secretory glands, in the in situ to invasive carcinoma transition. These cells are placed at the interface between luminal epithelial cells and the stromal compartment, which favors their cross-talk with all other cell types comprising the tumor micro-environment. To obtain some clues about thi...
Epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. Here a case of 58-year-old female presented with left cheek swelling of one-year duration. CT scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. Histological examin...
Epithelial myoepithelial carcinoma is a rare low grade malignant salivary gland neoplasm that most commonly occurs in the parotid gland but can also arise in minor salivary glands. We report a case of primary epithelial myoepithelial carcinoma of submandibular salivary gland in a 65 year old female who presented with left cheek swelling of six months duration. CT scan revealed a localized subma...
To describe our experience with a case of epithelial myoepithelial carcinoma that was reported as two different entities and thus proved to be challenging case. : Retrospective review histo-pathological reports detailed work up final findings treatment. Four year follow the patient shows successful treatment no recurrence. High index suspicion evaluation IHC testing is needed in tumours present...
The transition of ductal carcinoma in situ (DCIS) to invasive carcinoma is a poorly understood key event in breast tumor progression. Here, we analyzed the role of myoepithelial cells and fibroblasts in the progression of in situ carcinomas using a model of human DCIS and primary breast tumors. Progression to invasion was promoted by fibroblasts and inhibited by normal myoepithelial cells. Mole...
Adenomyoepithelioma (AME) is a rare benign tumor composed of myoepithelial cells (MECs) which are located beneath the epithelial cells of exocrine glands, especially in breast and salivary glands. These tumor cells show biphasic proliferation of epithelial and MECs. Malignant AME is characterized by distant metastasis, local recurrence, cytologic atypia, high mitotic activity and infiltrating t...
