Mucoepidermoid carcinoma involving the palate with lamellated calcifications: A notable finding

Abstract

Mucoepidermoid carcinoma (MEC) is a malignant glandular epithelial neoplasm of the salivary glands with an unpredictable behavior and a tendency to recur. The tumor is composed of mucous secreting cells, epidermoid cells, intermediate cells, columnar cells, and clear cells in varying proportions. Calcification in the salivary gland tumors is less common and minuscule in size; these can be seen in the benign tumor-like pleomorphic adenoma to malignant tumor-like MEC. Calcifications in MEC are considerably sparse and commonly associated with high-grade tumors. We present a case of MEC with lamellated calcifications present in the palate of a 43-year-old male patient.

Mucoepidermoid carcinoma with metaplastic bone formation—A deceptive radiological presentation

“…21 Intra-tumoural calcifications associated with MEC are rare, with only 12 cases reported in the literature. [12][13][14][15][16][17][18] MECs with associated calcifications appear to arise more frequently in the conventional and clear cell variants, mostly involving the minor salivary glands of the palate. 13 Only one case of MEC with calcifications has been reported in the parotid gland.…”

“…MECs containing calcifications are rare, but well described in the literature 12–18 . In contrast, there are only two case reports of MECs showing intra‐tumoural bone formation 12,19 .…”

“…11 MECs containing calcifications are rare, but well described in the literature.
