1.Mucoepidermoid Carcinoma of the Hard Palate: a Rare Cause of Hypervascular Tumor.
Yonsei Medical Journal 2003;44(4):723-726
A highly vascular tumor of the head and neck, with the exception a true vascular lesion, has rarely been observed. We report a rare case of a large, highly vascular, mucoepidermoid carcinoma (MEC) of the hard palate in a 28-year-old woman. The highly vascular channels were identified by ultrasonography and angiography. This case is noteworthy in that a large, highly vascular tumor of the minor salivary gland simulated a vascular lesion. When preoperative imaging demonstrates large vascular channels, preoperative angiography will benefit surgical management and embolization should be considered if possible.

Although the head and neck region is recognized as the most common location for peripheral nerve sheath tumors, central involvement, particularly in the jaw bones, is quite unusual. Neurofibroma is one of the most common nerve sheath tumors occurring in the soft tissue and generally appears in neurofibromatosis 1 (NF1 or von Recklinghausen's disease). Malignant peripheral nerve sheath tumors (MPNSTs) are uncommon sarcomas that almost always arise in the soft tissue. Here, we report four cases of intraosseous peripheral nerve sheath tumors occurring in the jaw bones and compare the clinical, radiologic, and pathologic findings in order to make a differential diagnosis.
