Abstract
The importance of both the CYP1A1 exon 7 (ile:val) and GSTM1 (0/0) polymorphisms in oral cancer susceptibility was assessed by examining polymorphic prevalences in 135 patients with oral cancer and 135 noncancer controls frequency-matched by age at diagnosis (+/- 5 years), race, sex, and institute of patient recruitment. The prevalence of the GSTM1 (0/0) genotype was approximately 51% in both cases and controls. The prevalence of the CYP1A1 (ile:val) polymorphism [including both the (ile/val) and (val/val) genotypes] was significantly higher in cases as compared to controls (17.6% versus 7.6%, respectively; crude odds ratio, 2.6; confidence interval, 1.2-5.7). No association was observed between polymorphic prevalence and levels of smoking or alcohol consumption in cases. These results suggest that the GSTM1 null genotype is not associated with oral cancer risk. These results also suggest that individuals with the CYP1A1 exon 7 ile:val polymorphism are at increased risk for oral cancer, and that this risk may not be influenced by differences in exposure to tobacco smoke.

Abstract
An apparent relationship between breast cancer and salivary gland cancer has been observed, and there is one report in the literature that describes estrogen receptors in normal salivary gland and salivary gland cancers. With the use of a monoclonal antibody against estrogen receptor protein and the avidin-biotin immunoperoxidase procedure, we were unable to demonstrate estrogen receptors in formalin-fixed paraffin-embedded sections of either polymorphous low-grade adenocarcinoma or adenoid cystic carcinoma of salivary gland origin.

Abstract
Cutaneous T-cell lymphoma rarely involves the oral cavity. Only 14 detailed cases of oral cutaneous T-cell lymphoma have been described in the English-language literature; this report describes eight additional cases observed among 824 patients evaluated at our cutaneous T-cell lymphoma center since 1968. Oral involvement occurs late in the course of cutaneous T-cell lymphoma and usually is associated with poor prognosis; most patients die of disease complications within 3 years of the diagnosis of oral involvement.

Abstract
Studies were undertaken to determine if there is a statistical correlation between radon levels and the incidence of salivary gland tumors because of high levels of radon in Pennsylvania. In Part I of the study, the incidence of minor salivary gland tumors accessioned by Temple University, Emory University, and University of Southern California from 1986 to 1988 were correlated with average radon levels in the three locations with the use of standard statistical analyses. In Part II, the occurrence of malignant salivary gland tumors was obtained for each of the 67 counties in Pennsylvania from 1986 to 1988 and correlated statistically with radon levels and population figures in each of those counties. A statistically significant correlation between radon levels and incidence of salivary gland tumors could not be demonstrated in either case.

Abstract
Five cases of amyloidosis involving structures in the oral cavity are reported. Three cases appeared to be secondary systemic amyloidosis, one case was the systemic form associated with multiple myeloma, and one case appeared to represent nodular or localized amyloidosis. All cases appeared in persons over 63 years of age, and the most common area of involvement was the tongue. The nature of so-called amyloid deposits in certain odontogenic tumors is discussed in light of recent knowledge of amelogenins and enamelins.

Abstract
Less than 5% of patients with metastatic cervical carcinoma will not have a detectable primary site despite a proper work-up. Recent aids for these diagnostic problems include fine needle aspiration and immunohistochemical panels to differentiate undifferentiated carcinoma from melanoma and/or lymphoma. CT scanning can suggest areas in the upper aerodigestive tract for biopsy and can be helpful in suggesting the pathology of the enlarged lymph nodes. EBV titers are often elevated when a nasopharyngeal carcinoma is small. Aggressive treatment of the occult primary patient with metastatic melanoma, thyroid cancer, and metastatic cancer presumed to arise from the skin of the head and neck or the mucous membranes of the upper aerodigestive tract is indicated as long-term survival is often achieved.

Abstract
Disfiguring facial edema and elevated intracranial pressure often accompany ligation and excision of the internal jugular veins (IJV) during simultaneous or staged bilateral radical neck dissection. To minimize this morbidity, unilateral reconstruction of the IJV was undertaken at the time of second-side neck dissection in 11 patients. Five patients underwent reconstruction with the spiraled saphenous vein (SVG) and in six patients 10 mm externally supported polytetrafluoroethylene (e-PTFE) was used. Prebypass jugular venous stump pressures (JVPs) were measured and ranged from 28/17 to 75/54 mm Hg with mean pressures of 17 to 62 mm Hg. Two patients had simultaneous neck dissections and nine had staged dissections. The staged interval ranged from 0.3 to 33 months. Six of nine staged reconstructions were right-sided and three of nine were left-sided. Low molecular weight dextran was started intraoperatively, regional heparinization was used in all but two cases, and platelet inhibitors were continued postoperatively in all patients. Additional time in the operating room was 45 minutes (mean). All patients have been followed up 2 to 18 months postoperatively. B-mode ultrasonography, Doppler spectrum analysis, CT scan with contrast, and magnetic resonance imaging were used to assess patency. Four of five SVGs and three of six e-PTFE grafts have remained functional, which resulted in an overall patency rate of 64%. Four grafts (one SVG, three e-PTFE) failed in the immediate postoperative period. All grafts in patients who had a mean JVP greater than 30 mm Hg remained patent, whereas those in patients with lower stump pressures thrombosed.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Three patients with chordomas of the clivus and the upper cervical spine underwent the removal of their tumors through a transoral approach with labiomandibular splitting and microsurgical techniques. This surgical approach provided excellent visualization of the anterior craniocervical area and allowed a gross total removal in each case. Although the lesions in our patients were chordomas, this approach could also be used for other surgical lesions in this area.

Abstract
Although there are arguments for different approaches, we have presented a format based upon the current literature and our clinical experiences for the management for thyroid nodules and cancers. The limited value of suppressive therapy in solitary nodules is stressed. Lobectomy with isthmectomy is the initial surgical procedure for dominant nodules. Total thyroidectomy for proven thyroid cancers is performed when possible. Regional lymph nodes in the central or visceral compartment are removed therapeutically by a modified technique in order to prevent significant functional loss and deformity. In the postoperative period, radioactive iodine therapy can be extremely beneficial. Postoperative thyroid suppressive therapy is useful in patients with thyroid cancer although a third or more of these tumors will eventually escape from beneficial effects. Clinical experiences of recurrent or metastatic thyroid cancer regressions following suppression therapy are difficult to document.

Abstract
Five cases of mucoepidermoid carcinoma of the parotid gland were studied ultrastructurally. In addition to epidermoid cells (tonofilament-rich) and mucous cells, three forms of intermediate cells were identified: mitochondria-rich cells, glycogen-rich cells, and ribosome-rich cells. Transitional forms of all cell types were observed. Ultrastructurally, cells rich in glycogen appeared to be the "clear cells" by light microscopy; cells rich in ribosomes appeared basophilic under light microscopy. Mitochondria-rich cells were lightly eosinophilic under light microscopy.

Abstract
In a 20 year period seven cases of craniocervical chordoma were seen and treated. Since it is not possible to completely resect these lesions, the aim of treatment has been to debulk the tumor as much as feasible and employ postoperative irridation. Palliation is the most that can be hoped for, and minimal success in delaying the natural history of the tumor has been achieved. Surgery for relief of symptoms secondary to bulky recurrence is indicated for palliation, as is a repeat course of x-ray therapy. Isolated cases of long-term useful survival have followed doses in the range of 10,000 rads or more [19,20]. This therapy is usually given in smaller increments of an initial dose when there is evidence of recurrent tumor or pain [2]. However, whenever the dosage to the spinal cord or the base of the brain exceeds 4,000 rads, there is a concern about possible permanent radiation damage. These patients are difficult to care for late in the course of their disease when multiple cranial nerve paralysis, long tract signs, and intractable pain become progressively severe. Chordomas usually remain localized; however, about 10% metastasize distally. One case is presented of a large retropharyngeal mass with destruction of the second cervical vertebra that recurred locally in 3 months despite usual treatment; distal bony metastases were found 3 years after initial treatment. The histology of the lesion, its recurrence, and distal bony metastases were essentially indistinguishable from the other lesions that remained localized. Short periods of palliation from severe local pain and exquisite tenderness have been achieved by local resection of the involved bones.

Abstract
Fresh surgical specimens of sixteen cases of oral squamous-cell carcinoma were processed for electron microscopic study. All cases were histologically graded as moderately differentiated carcinoma. As compared to normal oral stratified squamous epithelium, some unusual ultrastructural features were present in carcinoma. These features were spherical or ovoid nuclear bodies composed of concentrically arranged filaments and granules, clustered ribosomes, many lysosomal bodies, cell residues in other cells, absence and multilayering of basal lamina, pseudopodal cytoplasmic projections, microfilaments in peripheral cytoplasm, clusters of swirled tonofilaments, intracytoplasmic desmosomes, and a small amount of glycogen. These features are interpreted as being related to hyperactivity, phagocytosis, locomotion, and differentiation of cancer cells.

Abstract
Twenty-five cases of granular-cell tumor of the oral cavity are reported. The clinical findings are similar to previously published data. Of five cases studied by electron microscopy, three were processed directly from fresh surgical specimens and two cases were processed following initial formalin fixation. The granules for the most part are morphologically compatible with lysosomes except for a single variety containing viruslike particles. There is increasing evidence in support of a neural origin, but the indications are that more than one cell type may be the progenitor of granular cells of the granular cell tumor.
