The Rothmund-Thomson syndrome (RTS), also called poikiloderma congenitale is a rare autosomal recessive disease first described in 1868. This syndrome includes most frequently seen skin lesions (atrophy, telangiectases, pigmentation), cataracts and bone defects (dysostosis, dysplasia). Some authors describe an association with malignancy. We report three cases of Rothmund-Thomson syndrome associated with osteosarcoma. After cutaneous epithelioma, osteosarcoma is the most frequent malignancy. Thus, patients with RTS need a careful survey. The treatment did not differ from sporadic osteosarcoma. Chemosensitivity and toxicity are also not different.

The content of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (Ca 19-9), carbohydrate antigen 15-3 (Ca 15-3) and the expression of LewisY related carbohydrate antigens in benign and malignant pleural effusion were determined. These included 35 malignant pleural effusions: 13 breast cancers, 12 lung cancers (6 squamous cell carcinomas, 5 adenocarcinomas and 1 microcytoma), 2 mesotheliomas, 1 epithelioma, 1 kidney cancer, 1 hepatocarcinoma, 1 colon carcinoma, 3 lymphomas, 1 osteosarcoma and 9 benign pleural effusions. We showed that pleural fluid content of CEA, Ca 19-9 and Ca 15-3 were higher in malignant than in benign effusions. However CEA levels in squamous lung cancers were very high in both serum and pleural fluids whereas its levels were only slightly above the cut-off in breast cancers and in lung adenocarcinomas. Serum and pleural fluid Ca 15-3 values were higher in breast and in lung cancers with the highest values in the patients with breast cancer. Furthermore, the LewisY related carbohydrate antigens, evaluated by the reactivity of the cell extracts to MAb B3, were expressed only in breast cancers. These data suggest that pleural fluid content of CEA, and Ca 15-3 associated with the immunoblotting of cell extracts with MAb B3 appear to be very useful to improve the diagnosis of malignant pleural effusions.

We conducted a retrospective case-series review to identify the various diagnoses of neoplasms of the nasal cavity and paranasal sinuses in a pediatric population. Our study group was made up of 54 children-23 boys and 31 girls, aged 8 months to 16 years (mean: 9 yr). All patients had been diagnosed with a tumor of the nasal cavity or paranasal sinuses between Jan. 1, 1955, and Dec. 31, 1999, at one of four university-based, tertiary care referral centers. We compiled data on tumoral characteristics (location, size, and histopathology), morbidity and mortality, and rates of recurrence. Lesions included adnexal neoplasm, ameloblastic fibro-odontoma, basal cell carcinoma, benign fibrous histiocytoma, blue nevus, chondrosarcoma, compound nevus, epithelioma adenoides cysticum, esthesioneuroblastoma, Ewing sarcoma, fibrosarcoma, giant cell granuloma, granulocytic sarcoma, hemangioma, hemangiopericytoma, Langerhans cell histiocytosis, lymphangioma, lymphoma, melanoma, neuroblastoma, neurofibroma, ossifying osteofibroma, osteochondroma, osteosarcoma, port wine stain, rhabdomyosarcoma, Spitz nevus, and xanthogranuloma. To the best of our knowledge, this is the largest such study of its kind to date. We believe that the large size of this study and the data on disease incidence will allow clinicians to be better informed of the differential diagnosis of neoplasms of the nasal cavity and paranasal sinuses in the pediatric population.
