Oncocytoma of the salivary glands is a rare tumor that usually follows a benign course and, in most cases, can be cured by surgical resection. The authors report a rare case of multiple bilateral parotid oncocytomas that presented clinically with two palpable parotid masses. Both CT and MRI scans demonstrated multiple masses in each parotid gland. The(More)
Eight cases of metastatic hypernephroma to the head and neck are presented with CT documentation. Hypernephroma is the third most common infraclavicular tumor to metastasize to the head and neck. Such metastases occur in about 15% of patients with this neoplasm, and nearly 8% of patients with this tumor present with disease in the head and neck region.(More)
Pilomatrixoma is an uncommon benign tumor arising from hair follicles. They occur most commonly in the head and neck region, and are usually found in girls during the first two decades of life. These tumors may contain calcification, which, when present, is helpful in suggesting the diagnosis. We present a classic case of pilomatrixoma in the cheek of a(More)
Parotid pleomorphic adenomas are usually benign, solitary, ovoid masses. Occasionally, these tumors may be highly lobulated and clinically mimic multiple lesions. Actual multiple benign mixed tumors are rare as are malignancies that occur in these pleomorphic adenomas. Of these malignancies, the most common type is the carcinoma ex pleomorphic adenoma. Two(More)
In the past reconstruction of large auricular defects more than 2 cm have been repaired with the use of local skin flaps from various sites in multiple stages. This entails longer hospitalization and a poorer aesthetic result. We developed a postauricular myocutaneous flap that has been used successfully in five patients. The cosmetic results are superior(More)
A case of primary chordoma of the maxillary sinus is presented. The embryology of the notochord is reviewed and it is suggested that the frequently used adjective "ectopic" is a misnomer. The literature of primary paranasal sinus chordomas is reviewed and the clinicopathological features described. It is emphasized that these lesions can mimic other benign(More)
From day 12 to 16 of gestation a highly circumscribed zone of cellular degeneration has been observed in the otocyst of more than 50 normal rats. This zone appears to be produced by selective or programmed cell death, and results in the elimination of unneeded cellular elements. That cells in this zone are also selectively destroying subcellular organelles(More)
