Audit of clinical information and diagnoses supplied to the pathologist following biopsy of oral squamous cell carcinomas.

Strict criteria for the biopsy of oral lesions suspected to be squamous cell carcinoma (SCCA) are difficult to find. Evaluation of the patient's history and clinical findings should help the clinician to accurately diagnose oral cancer. Our study attempts to compare and correlate cases that have the histopathologic diagnosis of oral SCCA with the data submitted by the clinician to the oral pathologist. We find the more information the clinician lists in the biopsy request form, the more likely the correct clinical diagnosis of oral SCCA is. We also show that when risk factors such as tobacco and alcohol use are mentioned by the clinician, the percentage of correct clinical diagnosis is increased.

Accuracy of clinical examination versus computed tomography in detecting occult lymph node involvement in patients with oral epidermoid carcinoma.

PURPOSE: To determine the accuracy of clinical examination versus computed tomography (CT) scanning in detecting positive cervical lymph nodes (N) in patients with epidermoid carcinomas of the oral cavity, 27 patients with epidermoid carcinomas were reviewed. PATIENTS AND METHODS: The patients underwent 40 neck dissections, 20 with N- and 20 with N+ necks histologically. All patients were examined by the same clinician, and all CT scans were read by the same radiologist. Patients with clinical and CT N- necks underwent neck dissection only if the neck had to be entered to resect the primary tumor or if the primary tumor was T3 or T4 with a high probability of microscopic metastasis. RESULTS: Of the 20 necks that were histologically N-, 16 (80%) were clinically diagnosed as N- and 4 (20%) N+ versus 18 (90%) N- and 2 (10%) N+ diagnosed by CT scan. Of the 20 histologically N+ necks, 12 (60%) were clinically diagnosed as N+ and 8 (40%) N- versus 11 (55%) N+ and 9 (45%) N- diagnosed by CT scan. All lymph nodes diagnosed as N- by both clinical examination and CT scan were less than 1 cm in diameter. Overall, clinical examination of the neck was correct in 28 patients (70%) and the CT scan was correct in 29 patients (73%). Both clinical examination and CT scan were more accurate in diagnosis of N- necks. In 31 necks (78%), the CT and clinical examination were in agreement. Of these, 10 of 10 (100%) were correctly positive. Of the 21 in which both were negative, 14 were histologically N-, and 14 (67%) were correct. Overall, in those cases in which both CT and clinical examination were in agreement, the diagnosis was correct in 24 of 31 (77%). CONCLUSION: These results suggest that there is no significant difference in the accuracy of clinical examination versus CT scanning in detecting both positive and negative cervical nodes. When both CT and clinical examination agree, positive cervical nodes are almost always correctly diagnosed. However, one third of the negative cervical nodes were incorrectly diagnosed. Improved methods for detecting occult disease are still needed.

Lobular adenocarcinoma of breast metastatic to the mandibular condyle. Report of a case and review of the literature.

A case of metastatic breast adenocarcinoma to the condyle in a 55-year-old white woman is reported. Highlights of this case presentation include the rarity of reported metastatic lesions to the condyle, a negative bone scan 2 months before the bone biopsy, the existence of a pathologic fracture as the only persistent symptom of the lesion, initial symptoms suggestive of temporomandibular joint disorder, and the uncommon type of breast carcinoma.

Multiple synchronous bilateral Warthin's tumors of the parotid glands with pleomorphic adenoma. Case report and review of the literature.

A case of multiple bilateral synchronous Warthin's tumors of the parotid glands with a simultaneous pleomorphic salivary adenoma in one patient is presented. This case appears to be unique. Only three previous cases of multiple synchronous bilateral Warthin's tumors have been reported. The occurrence of salivary tumors of different histologic types in the same patient is also rare. Twenty cases of Warthin's tumor that occurred with pleomorphic salivary adenoma were found in our review of the literature. However, none of these represented synchronous bilateral multiple Warthin's tumors.

Psoriatic arthropathy of the temporomandibular joint.

A case of psoriatic arthritis of both temporomandibular joints is described with a brief review of the literature and discussion on the management of this condition. To date, psoriatic arthritis has been successfully treated by conservative means. In the case reported, surgical replacement of the condyles became necessary to eliminate pain and restore function.

Vascular metastatic renal carcinoma of the maxilla. Report of two cases.

Metastatic lesions of the jaws are unusual and the maxilla is rarely affected. Because of their vascular nature metastases from renal cell carcinoma may be embolized in order to palliate the patient. Two cases of renal carcinoma metastasizing to the maxilla are reported. Management of the condition is reviewed.

Aneurysmal bone cyst of the zygomatic bone.

Aneurysmal bone cysts are a rare finding in the facial bones and jaws. Only one previous case of this entity affecting the malar bone could be found in the literature. Ultrasound and isotope scan features of this entity are described.

Angiomyoma of the temporal region.

A case of angiomyoma of the temporal region is presented. Judging from the number of reported cases this is an uncommon site for the tumour to occur. The clinical and histopathological features of smooth muscle tumours of the superficial tissues of the head and neck are reviewed.

Preserving the great auricular nerve in parotid surgery.

This study compares the sensory morbidity associated with preservation of the posterior branch of the great auricular nerve and sacrifice of the nerve during routine parotid surgery. Twelve patients were divided into two groups. Half the patients had the posterior branch of the great auricular nerve preserved and the other half had the nerve sacrificed in the standard manner. Sensory testing was carried out at 3 monthly intervals for 1 year. The results showed significantly less sensory loss to the skin of the ear and the angle of the mandible in those patients where the nerve was preserved.
