Mucoepidermoid carcinoma, low grade - Case 199
Mucoepidermoid carcinoma is a rare lung tumor tht usually arises within the central bronchi. Typical cases contain mucus-secreting goblet cells, intermediate cells and squamous cells. Low grade tumors predominate and are characterized by mucous-filled cystic structures without significant cytologic atypia. High grade tumors tend to have solid areas of growth with significant cytologic atypia and mitotic activity. HIgh grade mucoepidermoid carcinomas may contain a low grade component.
This image shows sheets of intermediate cells contaiing numerous mucous-filled cysts. The stroma is heavily infiltrated by chronic inflammatory cells.
