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...

Dedifferentiation is defined as high-grade malignant tumor development out of a low-grade malignant tumor. We present an adenocarcinoma tumor of the parotid gland that was dedifferentiated from a low-grade epithelial-myoepithelial carcinoma and was followed up for 3 years. Our patient, a 46-year-old female, presented with a left parotid mass of 20-year duration. Histopathologic results showed t...

BACKGROUND Radiation-induced salivary gland tumors are well described in the literature, with mucoepidermoid cancer being the most common histologic entity. Epithelial-myoepithelial carcinoma is a rare tumor accounting for <1% of all tumors in the salivary glands. METHODS AND RESULTS We describe the first case of radiation-induced epithelial-myoepithelial carcinoma in the English-language med...

INTRODUCTION Epithelial-myoepithelial carcinoma is a low-grade malignant salivary gland neoplasm with a biphasic cell population that encompasses around 1% of all salivary neoplasms. METHOD We present different cases of epithelial-myoepithelial carcinoma, with special emphasis on histopathology, differential diagnosis, relevant prognostic factors and follow-up. RESULT This study included 8 ...

Myoepithelial carcinoma, the malignant counterpart of benign myoepithelioma, is one of the rarest salivary gland neoplasms. It is composed almost exclusively of tumour cells with myoepithelial differentiation, characterized by infiltrative growth and potential for metastasis. We herein, report a case of myoepithelial carcinoma in a 50 years old male with reticular morphology. Reticular variant ...

Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found in the tracheobronchial tree. We report the first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented with altered mental status and hypercalcemia. Imaging revealed diffuse intra-thoracic and intra-abdominal lymphad...

A case of epithelial myoepithelial tumour originating from the tracheal gland in a 57 year old woman is described. The tumour was removed by segmental tracheal resection and end-to-end anastomosis. Histologically, the tumour comprised clear cells and presented a monophasic pattern. Immunohistochemical analysis showed that the tumour cells were positive for both S-100 protein and smooth muscle a...
