mucoepidermoid carcinoma
Digital cases
Case 95 (HPC:95)
Grade
Mucoepidermoid carcinoma (MEC) shows differences in biological behaviour depending mainly on its histological grade. High-grade tumours usually have an aggressive biological course and they require additional oncological treatment after surgery.
Localization
salivary mucoepidermoid carcinoma
thymic mucoepidermoid carcinoma
bronchial mucoepidermoid carcinoma (pulmonary mucoepidermoid carcinoma)
Variants
oncocytic mucoepidermoid carcinoma
Cytogenetics
t(11;19)(q21;p13) translocation (#8019965#)
Molecular biology
MECT1/MAML2 fusion gene by t(11;19)(q21;p13) translocation (55%) (#16444749#)
- Mucoepidermoid carcinomas (MECs) of the salivary and bronchial glands are characterized by a recurrent t(11;19)(q21;p13) translocation.
- It results in a MECT1-MAML2 fusion in which the CREB-binding domain of the CREB coactivator MECT1 (also known as CRTC1, TORC1 or WAMTP1) is fused to the transactivation domain of the Notch coactivator MAML2.
Activation of the EGFR/ERK pathway in high-grade mucoepidermoid carcinomas of the salivary glands. (#20664595#)
- The EGFR/ERK pathway is activated in high-grade MECs with aggressive behaviour.
- Patients with these tumours who require oncological treatment in addition to surgery could benefit from EGFR and mitogen-activated protein kinase pathway inhibitors.
