The intraosseous course of the mandibular incisive nerve in the mandibular symphysis.

The use of the mandibular symphysis as a source of autogenous bone grafting material has been well documented. Currently, no references in the literature describe the intraosseous distribution of the neurovascular complex anterior to the mental nerve with respect to its position buccolingually and apicocoronally. The objective of this study was to evaluate the distribution of the incisive nerve and measure its location buccolingually and apicocoronally in the anterior mandible and determine its possible significance to clinical practice. According to macroscopic dissection, the mandibular incisive nerve is a normal structure that typically extends closer to the midline than previously reported. To reduce postoperative neurovascular morbidity, this should be considered when using the mandibular symphysis as a source of autogenous bone or during placement of implants in the anterior mandible.

Primary leiomyosarcoma of the aorta.

A case of primary leiomyosarcoma of the abdominal aorta is reported. The tumor replaced the full thickness of the aortic wall with formation of a large saccular aortic aneurysm filled with an admixture of tumor and mural thrombus. Electron microscopy of the surgical biopsy of the tumor revealed neoplastic smooth muscle cells with myofilaments and a discontinuous basal lamina. To our knowledge, leiomyosarcoma of the aorta has never been reported.

Obstructive jaundice caused by hepatocellular carcinoma. Report of three cases.

A cholestatic syndrome secondary to extrahepatic biliary obstruction as the presenting manifestation of hepatocellular carcinoma is described in three cases. The mechanism is related to the invasion of intrahepatic bile ducts by the carcinoma. The consequent mechanical obstruction is due to either a continuous distally growing tumor cast of the biliary tree, distal migration of a necrotic tumor fragment, or hemobilia. In the cirrhotic patient with a predisposition for the development of liver cancer, the physician should be aware of the presentation with obstructive jaundice as a mechanical complication of hepatocellular carcinoma.

Multiform thyroid cancer-scintigraphic and echographic features.

In a patient with multinodular goiter, one of the three solid nodules harboring follicular carcinoma appeared functional in the 99mTc-pertechnetate image, yet "cystic" in both A-and B-mode echogram studies. The other two nodules corresponded in their image and echogram features and contained papillary and anaplastic carcinomas, and Hashimoto's thyroiditis. Clinical acumen proved to be the best guide in the management of this patient.
