Clear Cell Myoepithelial Carcinoma Arising from the Hard Palate with Metastasis to the Lungs

Figure 3

Representative images of oral mucosa with changes consistent with a malignant glandular epithelium neoplasm. The neoplastic clear cells were arranged in nests, cords, and anastomosing trabeculae embedded in hyalinized, acellular, predominantly basophilic stroma. The tumor demonstrated a nodular infiltrative growth pattern, lacked overt ductal differentiation, and showed several areas of necrosis, including nests with comedo type necrosis.
