The exercretion of urinary total glycosaminoglycans (GAG) in a case of Rothmund Thomson syndrome associated with osteosarcoma was increased about 2--3 times that of normal control. Since the excretion of urinary total GAG in two cases of osteosarcoma was within normal range, the increased excretion of total GAG might be on account of the metabolic disorder of GAG in Rothmund Thomson syndrome. The prominent fractions obtained by Dowex 1 column chromatography from this syndrome were 0.75 M Fr and 1.0 M Fr, in which the major GAG were indicated to be partially degraded forms of heparan sulfate and chondroitin sulfate, respectively.

Urinary neutral oligosaccharides of various connective tissue diseases were studied by gel-filtration through Sephadex G--10 after treatments with cetylpyridinium chloride (CPC), Dowex 50 (H+ form) and Dowex 1 (Cl- form), in succession. Increased excretion of urinary glucose-containing oligosaccharides, specifically glucosylgalactose was observed in most of the patients with chondrosarcoma, rheumatoid arthritis, Werner's syndrome, Rothmund Thomson syndrome and Morquio's disease. However, urinary excretion of neutral oligosaccharides in the patients with osteosarcoma and other tumorous conditions, and some systemic disorders in the connective tissues, examined in the present study, showed almost normal values. It is indicated, therefore, that the activity of glucosidase in insufficient for the glucose-containing oligosaccharides produced from the ground substance(s) in the former type connective tissue diseases.

Rothmund Thomson syndrome (RTS) is a rare autosomal recessive disorder characterised by poikiloderma, dermal atrophy, dystrophic nails, short stature and hypogonadism. An increased incidence of malignancy has been reported in patients with this syndrome secondary, it is postulated, to DNA repair defects. We report the occurrence of an osteogenic sarcoma in an 11-year-old Irish girl with RTS. Although fibroblast cultures demonstrated enhanced radiosensitivity, there was no undue toxicity associated with treatment, which included methotrexate, cisplatinum and Adriamycin. Following conservative surgery, she is currently off treatment and disease-free 2 years from diagnosis.

We report two new cases of Rothmund-Thomson syndrome which emphasize the less well-known non-dermatological complications, namely: hypodontia, soft tissue contractures, proportionate short stature, hypogonadism, anaemia and osteogenic sarcoma. Genetic analysis of these and previously reported pedigrees supports autosomal recessive inheritance.

A 7 years old girl with Rothmund-Thomson syndrome is described. A detailed study of the dermatologic lesions has been performed. The parent's girl are first cousins and one of her brothers, also having the Rothmund-Thomson syndrome, died from an osteosarcoma of the tibia at the age of 11. This familial observation gives support to the uniqueness of the Rothmund-Thomson syndrome with autosomal recessive inheritance.

The first case of osteosarcoma in a 13 year old boy with Rothmund-Thomson syndrome is reported. The association between these two conditions is uncertain.

A 10-year-old girl with Rothmund-Thomson syndrome developed a fibular osteosarcoma. Standard chemotherapy produced intolerable toxicity, necessitating a modification of therapy. Initial DNA repair studies on skin fibroblasts were abnormal, but repeat studies failed to reproduce the defects.

Rothmund-Thomson syndrome is a rare genodermatosis that features a progressive, early-onset poikiloderma, a high incidence of juvenile cataracts, stunted growth, and a wide range of skeletal abnormalities. We report the seventh case of osteosarcoma in a patient with Rothmund-Thomson syndrome and review the previous reports describing this association.

Two children who had the Rothmund-Thomson syndrome and developed osteosarcoma are reported. The 10 previously reported cases are reviewed. The osteosarcomas developed at a younger age than normally expected and 66% occurred in the tibia/fibula. Four of the five patients for whom information was available showed undue sensitivity to cancer chemotherapy agents with prolonged myelosuppression and severe mucositis. It is recommended that doxorubicin in particular should be given with extreme caution in such patients.

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.
