carcinomas (MECs) had always been recognized as salivary gland tumors mainly steming from parotid and submandibular salivary glands.
A group of specialized researchers in Biolab -- the Kingdom's leading accredited diagnostic laboratory, offering more than 700 medical diagnostic services across its branches -- diagnosed a 70-year-old Jordanian patient with a rare breast cancer tumor known as Breast Mucoepidermoid
The most common malignant tumour is mucoepidermoid
carcinoma followed by adenoid cystic carcinoma.
Histologically, the tumor was consistent with a high-grade mucoepidermoid
carcinoma, characterized by the presence of epidermoid, intermediate, and mucous-producing cell types.
The basal cell carcinoma palisading arrangement of basaloid cell at periphery, squamous cell carcinoma (SCC) intercellular bridging or keratinization, malignant melanoma of large pleomorphic diffuse infiltration of large pleomorphic epithelioid tumor cell with melanin pigment and mucoepidermoid
carcinoma sheets of mucous, squamous, and intermediate cells were found in Figure 1.
carcinoma with eosinophilia of the thyroid.
carcinoma of the lung (MEC) is a tumor of low-malignant potential of bronchial gland origin.
An 80-year-old woman presented with a history of T4N0 mucoepidermoid
carcinoma in the nasal cavity (figure 1) treated with maxillectomy with multiple free-flap reconstructions and postoperative radiation approximately 5 years earlier.
6%) followed by salivary adenocarcinomas such as mucoepidermoid
and adenoid cystic carcinoma (23.
Some of these lesions are primary laryngeal adenocarcinomas, metastatic adenocarcinoma, salivary glandular tumours like acinic cell carcinoma, mucoepidermoid
carcinoma or adenoid cystic carcinoma of the larynx.
Anatomically-based differential diagnosis for the parotid space * Parenchymal origin: Neoplasms (salivary gland), pleomorphic adenoma, Warthin's tumor, mucoepidermoid
carcinoma, adenoid cystic carcinoma, acinous carcinoma, oncocytoma, malignant mixed tumor (Figure 13A).
carcinoma (MEC) is the most-common malignant salivary gland tumor and is associated with one of the more clinically useful translocations, involving the MAML2 gene.
