Lung tumor-associated antigens of approximately 32,000 daltons were recognized by the use of sensitive radioimmunoassays and rabbit antisera, one raised against an extract of pooled human malignant lung tissues and another raised against a cell line derived from a human squamous cell carcinoma of the lung. These antigens differ from antigens described previously, including carcinoembryonic antigen and alpha-fetoprotein. The antigens were detected on 13 of 13 lung tumors (of all histologic types), fetal tissue, normal brain, 2 of 8 colon tumors, 2 of 9 prostate tumors, and 2 of 3 breast tumors, as well as on cell lines derived from lung tumors, neuroblastoma, human amnion, colon adenocarcinoma, and bladder tumors. They were not detectable on normal lung, liver, kidney, colon, or prostate tissues or on cell lines derived from osteosarcoma, fetal lung fibroblasts, transitional cell carcinoma, and squamous cell carcinoma of the skin. Lung tumors of different histologic types were concluded to express common, tumor-associated oncofetal antigens that are found less often on tumors of other organs.

Nineteen cases with malignant tumors in the nasal cavities have been treated at the department of otolaryngology, Yokoharma City University, during the 10 years from 1978 to 1987. 1. Cases were 8 males and 11 females, and their ages ranged from 27 to 84 years (Mean age: 64.6). 2. In the histological classification, 9 cases were the epithelial malignant tumors (squamous cell carcinoma 5; adenoid cystic carcinoma 2; transitional cell carcinoma 1; malignant pleomorphic adenoma 1), 9 cases were non-epithelial malignant tumors (malignant melanoma 6; malignant lymphoma 2; olfactory neuroblastoma 1), and one case was unclassified malignant tumor. 3. Cases with epithelial malignant tumors showed better prognosis after treatment of surgical and radiation therapy. But those of non-epithelial malignant tumor were worse. 4. A very rare case with malignant pleomorphic adenoma, originated at the lateral nasal wall was reported and its clinical features and treatment were discussed. This tumor has not been reported up to the present in Japan.

An investigation of the role of fine needle aspiration in the assessment of renal masses was carried out on 132 consecutive patients, 11 of whom were children. Selection was based on the presence of a solid or mixed solid and cystic renal mass that could not be defined by radiology, either in symptomatic patients or in patients to be submitted to embolization of the renal artery and at high surgical risk. Histologic and clinical data showed 49% of the cases to have a malignant, predominantly (45%) primary disease of the kidney and the remainder to have a nonneoplastic lesion. In five cases, the primary lesion was in the adrenal gland (three neuroblastomas and two pheochromocytomas). Sensitivity, specificity and predictive values for positive results were, respectively, 0.93, 0.96 and 0.935 because of a false-positive diagnosis in a case of multilocular cystic nephroma. Furthermore, in 43 of 65 cases (66%), consisting of 33 renal cell carcinomas, 1 transitional cell carcinoma, 3 Wilm's tumors, 1 neuroblastoma, 2 pheochromocytomas and 3 metastatic lesions, the histologic type could be ascertained on the tissue yielded by the fine needle aspiration. The findings stress the usefulness of this method for the clarification of radiologically not unequivocal space-occupying lesions of the renal area, especially when, in addition to the smears, histologic sections of paraffin-embedded tissues are available. Ultrastructural and immunohistochemical studies are cost-effective mainly in pediatric patients.

Ten patients under 20 years of age, with malignant tumors of the head and neck was treated at the Department of Otorhinolaryngology of Kitasato University Hospital from August 1971 to December 1989. The primary lesions were situated in the nose and paranasal sinuses in 3, middle ear in 2, epipharynx in 2, and parapharynx, esophagus, and neck in 1 patient. Histological examination indicated 3 rhabdomyosarcomas, 2 malignant lymphomas, and 1 each of neuroblastoma, malignant neuroendocrine tumor, transitional cell carcinoma, lymphepithelioma, and squamous cell carcinoma. The sites of origin and histopathology of malignant tumors in such patients usually differ from those in adults. Well differentiated squamous cell carcinoma of head and neck is common in adults but not in children, in whom non-epithelial malignant tumors or sarcomas are not rare. Radiotherapy is more effective for treating malignant tumors of the head and neck in young than in adults. Eight of 10 patients are still alive, 7 of whom for 5 years or more. Two with rhabdomyosarcoma died.

Tumours of the urachus are exceptional in children. They represent 0.01% of all tumours and consist of mucosecretory adenocarcinoma and, more rarely, transitional cell carcinoma. We report a 6-month-old child with a urachal mass which, following biopsy, was shown to be a neuroblastoma.
