Although no macrophages were identified, the cells observed in the anterior chamber of the affected eyes may represent an anterior migration of p...
متن کاملEpithelial-Myoepithelial Carcinoma of the Palate: Report of a Case and Review of the Literatures
Epithelial-myoepithelial carcinoma (EMC) is considered as a rare malignant salivary gland neoplasm with good prognosis, low recurrence rate and rare metastasis. Here we present a case of epithelial-myoepithelial carcinoma in a 42-year-old female with a swelling of 3-year duration in her palate. Histopathologic evaluation of the lesion demonstrated a well-circumscribed, biphasic salivary gland t...
متن کاملMyoepithelial carcinoma with contralateral invasive micropapillary carcinoma of the breast
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...
