Hypertrophic osteoarthropathy in children is rare, especially when it is associated with lung metastsis. The patient reported herein had metastic osteogenic sarcoma and failed to respond to chemotherapy or thoractomy. There are several theories as to the pathogenesis of osteoarthropathy, but none is totally convincing. Vagotomy or transection of intercostal nerves has been advocated to relieve the symptoms of osteoarthropathy.

Although an uncommon occurrence in childhood, hypertrophic osteoarthropathy secondary to tumors- most commonly to osteogenic sarcoma with pulmonary metastasis-may cause severe join pain and swelling. The syndrome should be considered in the differential diagnosis of acute arthritis in childhood

Hypertrophic osteoarthropathy and hypophosphatemic osteomalacia are both associated with neoplasm and unusual clinical syndromes. Although the etiologies of these conditions are unknown, their clinical courses are interesting, so we are reporting two cases of these conditions separately. Case 1: A 20-year-old man had an osteogenic sarcoma originating in the 2nd thoracic vertebra which was developing in the mediastinal region. He had complained of numbness and swelling in the left arm and of clubbing of the fingers of both hands. A chest radiograph showed a billiard-ball-sized, round opacity in the left upper mediastinal region. Periosteal new bone formation was demonstrated symmetrically in both humeri, radii, ulnae, femurs, tibiae, fibulae and metacarpals. Case 2: A 30-year-old man had complained of lower back, hip, knee and ankle pain and muscle weakness of five years' duration and was admitted to the National Yokosuka Hospital. Surum phosphorus was 0.7 mg/dl, alkaline phosphatase was 24.9 K.A. and glucosuria was noted. He had a fibrous xanthoma on the right thigh, and after removal of the tumor, his symptoms improved dramatically and pertinent laboratory data returned to normal. However, ossification of the ligaments of the spine subsequently developed.

We report a study of strontium kinetics in two patients who received 89Sr therapy for disseminated osteogenic sarcoma, together with estimates of absorbed dose to the principal metastases and to bone marrow. In neither patient did tumour uptake of strontium have a significant effect on whole-body retention. In one patient, whole-body strontium kinetics agreed closely with the ICRP standard model, while in the second, retention was extremely prolonged, probably due to hypertrophic osteoarthropathy. Strontium-85 scintigraphy, surface counting and high-resolution whole-body profiles agreed in showing that in both patients tumour turnover of strontium was very rapid, with a biological half-life of only a few days. Absorbed dose to tumour was found to be comparable in magnitude to the mean bone-marrow dose. We have no reason to believe that 89Sr therapy was of clinical benefit to either patient.

Hypertrophic osteoarthropathy (HOA), well known in adults, is rarely encountered in children. The clinical features include clubbing of the fingers and toes, arthritis, and a sometimes painful ossifying periostitis of the tubular bones. Apart from a hereditary form (primary HOA), most of the cases encountered in children are secondary and associated with conditions such as chronic suppurative lung processes (e.g., cystic fibrosis), congenital heart disease, biliary atresia, and polyposis coli. The association with malignant disorders, which is relatively common in adults, is very rare in children. In 1986 the authors published a case report of a patient with carcinoma of the nasopharynx who developed HOA. Another similar patient has been encountered. In both, the appearance of HOA was associated with a very poor prognosis. A meticulous research of the literature from 1890 to 1990 revealed only 24 children (19 boys, 5 girls) under the age of 18, with malignancy and associated HOA. Among them were 10 patients with a carcinoma of the nasopharynx, 8 with osteosarcoma, 3 with Hodgkin's lymphoma, 1 with a periosteal sarcoma, 1 with mesothelioma of the pleura, and 1 with carcinoma of the thymus. In five patients with HOA, there were no abnormalities of the lungs, mediastinum, or pleura, and none developed during the course of the disease. Many authors mention the predictive value of HOA, especially in association with malignant tumors. In contrast to suppurative processes in the lungs, in those with neoplastic disease involving the chest, HOA may precede pulmonary symptoms by 1-18 months. A striking feature of HOA in these instances is the reversibility of the complaints after successful treatment of the disorder of the chest, both in benign and malignant conditions. The present case is the second reported by the authors and the first description of a girl with carcinoma of the nasopharynx developing HOA.

Micro-computed tomography (muCT) is of great interest for palaeopathological examination because it is less invasive than histology. This study evaluates the diagnostic value of muCT for postcranial macerated bones. We investigated five specimens (osteomyelitis, tuberculosis, trauma, osteosarcoma and hypertrophic osteoarthropathy) of a pathology reference series by muCT and polarised light microscopy. The 3D muCT images allow an easy orientation within the specimen. Surface structures, thickness, continuity of the cortex and number, thickness and orientation of the trabeculae can be evaluated. The high number of muCT slices helps to choose the most interesting areas for further investigations. Grey value images display the degree of mineralisation. Yet, the differentiation between woven and lamellar bone is only possible using polarised light microscopy. muCT is a tool of high value for the examination of postcranial bone disorders. It cannot replace histological examinations completely because it cannot assess the bone quality (woven or lamellar). For the choice of the optimal location where slices for the microscopic investigation are later cut in heterogeneous samples, muCT is very useful. Therefore, we suggest performing the muCT examination first, followed by histology if necessary.
