[Clinical investigation of neuron-specific enolase, squamous cell carcinoma-related antigen and carcinoembryonic antigen in carcinoma of the lung].

Serum levels of neuron-specific enolase (NSE), squamous cell carcinoma-related antigen (SCC antigen) and carcinoembryonic antigen (CEA) were measured in 53 untreated patients with carcinoma of the lung. The positive rates of serum NSE were 17.0% in all patients with lung cancer, 53.8% in small cell carcinoma, 6.7% in adenocarcinoma, 5.0% in squamous cell carcinoma and 0% in large cell carcinoma; 0% in stage I, 14.3% in stage III and 26.7% in stage IV. The positive rates of serum SCC antigen were 45.3% overall, 70.0% in squamous cell carcinoma, 40.0% in adenocarcinoma, 23.1% in small cell carcinoma and 0% in large cell carcinoma; 42.9% in stage I, 57.1% in stage III and 46.7% in stage IV. In comparison with serum CEA, serum NSE and SCC antigen were much more specific in small cell carcinoma and squamous cell carcinoma, respectively. Moreover, serum levels of NSE and SCC antigen changed in parallel with the clinical course during the treatments. In conclusion, serum NSE and SCC antigen were considered to be very useful markers of lung cancer, especially of small cell carcinoma and squamous cell carcinoma, respectively.

Primary chondroid chordoma arising from the base of the temporal bone. A 10-year post-operative follow-up.

A 36-year-old male with a primary chondroid chordoma is presented. This tumour arose from the base of the temporal bone and extended to the mastoid cavity. It involved the facial nerve and was adherent to the internal jugular vein and internal carotid artery. The tumour was excised and the patient has been carefully followed up for 10 years. He has shown no evidence of local recurrence, intracranial extension of the residual tumour and distant metastasis.

Solitary neurofibroma of the esophagus.

A rare case of solitary neurofibroma located in the esophagus is reported. A large (4.2 X 4.0 X 3.0 cm) submucosal tumor was surgically removed from the midportion of the esophagus of a 64-year-old woman. Light and electron microscopic examination, and immunohistochemistry of S-100 protein in the tumor tissue confirmed neurofibroma. The patient had no evidence of von Recklinghausen's neurofibromatosis. A review of literature failed to find other reports of solitary neurofibroma of the esophagus with reliable histological diagnosis.

Desmoid tumor in the maxillary sinus: a case report.

Desmoid tumor in the maxillary sinus is a rare condition. The present case occurred in a 37-year-old male complaining of left nasal obstruction and dull pain in the nape of the neck. The clinical picture, pathology, diagnosis and prognosis are discussed and the literature is reviewed.

Lung cancer complicated by silicosis: a clinical and histopathological study.

A clinicopathological analysis was carried out on 16 cases of lung cancer complicated by silicosis, which were diagnosed from April 1975 to March 1983, and the results were discussed with a review of the literature. All of the patients were male, and a smoking habit with a Brinkman index of more than 500 was found in 14 of them (87.5%). Twelve cases (75.0%) had advanced tumors of clinical stages III and IV, suggesting that the early detection of lung cancer complicated by silicosis is difficult. Tumors were uniformly found in all lobes of the lung. Histological types were mainly epidermoid or undifferentiated carcinoma, with very few adenocarcinomas. Carcinogens from smoking seemed to be responsible for the carcinogenesis. Two cases were thought to be scar carcinomas.

Post-mortem prevalence of lymphocytic infiltration of the lacrymal gland: a comparative study in autoimmune and non-autoimmune diseases.

The prevalence of focal lymphocytic infiltration of the lacrymal gland was investigated in 131 autopsy cases, 115 without and 16 with autoimmune diseases (nine cases of systemic lupus erythematosus, three of rheumatoid arthritis and four of Sjögren's syndrome). Focal lymphocytic infiltration was observed in 63.5 per cent of patients without autoimmune diseases and in all of those with autoimmune diseases. In those without autoimmune diseases, the frequency of lymphocytic infiltration was higher among those older than 40 years, and there was no sex difference in prevalence. The incidence of moderate or severe infiltration (grade III or IV) was 7.8 per cent in patients without autoimmune diseases; 55.6 per cent in systemic lupus erythematosus; 66.7 per cent in rheumatoid arthritis; and 100 per cent in Sjögren's syndrome. The present observation suggests that focal lymphocytic infiltration is indicative of an immunological disorder of the lacrymal gland in systemic lupus erythematosus and rheumatoid arthritis. Epimyoepithelial island formation was observed in only one patient with Sjögren's syndrome.
