Primary epithelial myoepithelial lung carcinoma

Area of Science:

• Pulmonology
• Oncology
• Pathology

Background:

• Epithelial-myoepithelial carcinoma (EMC) is an exceedingly rare lung neoplasm.
• Typically originating from submucosal bronchial glands, EMC is more commonly found in salivary glands, breast, and sweat glands.
• Pulmonary EMC cases are scarce, with most reported as endobronchial tumors.

Observation:

• This report details an unusual case of primary epithelial-myoepithelial carcinoma of the lung.
• The identified tumor developed within the peripheral lung parenchyma, a location rarely described for this condition.

Findings:

• The case represents a primary epithelial-myoepithelial carcinoma originating in the peripheral lung parenchyma.
• This finding contrasts with the more common endobronchial presentation of pulmonary EMC.

Implications:

• This case expands the understanding of the anatomical locations and potential origins of pulmonary epithelial-myoepithelial carcinoma.
• Further research into peripheral lung parenchymal tumors is warranted to better characterize rare neoplasms like EMC.
