Abstract

Neuroendocrine carcinoma is a high-grade carcinoma with morphological and immunohistochemical features of neuroendocrine differentiation. Poorly differentiated neuroendocrine carcinoma which has two subtypes (small cell or large cell type) is extremely rare, especially in head and neck cancers. Metastatic neuroendocrine carcinoma to the oral and maxillofacial region is even rarer. We report a rare case with metastatic neuroendocrine carcinoma to the mandibular gingiva from the duodenum papilla. Surgeons may consider metastatic tumors as well as primary tumors, because neuroendocrine tumors are extremely rare in oral and maxillofacial region.

Abstract

In oral and maxillofacial surgery such as orthognathic surgery and open treatment of maxillofacial fracture, plate fixation is commonly performed. Although the removal of titanium miniplates is controversial, the plates are removed routinely or symptomatically. By excessive torque during the screw removal, stripping or breaking of screw heads may occur. Although miniplates and screws are used with angled screwdrivers for osteosynthesis in bilateral sagittal split osteotomy (BSSO) or open treatment of mandibular angle or subcondylar fracture, the removal of a damaged screw, especially with the angled screwdriver, is very difficult. Therefore, we report a simple method with a sterilized surgical glove for removal of the stripped screw.
