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.

Inclusions of periodic acid-Schiff-positive, amylase resistant material were found within skeletal muscle fibers adjacent to an osteosarcoma in the proximal femur of an 8-year-old intact female Cocker Spaniel dog (dog No. 1) and adjacent to a synovial cell sarcoma of the stifle joint in a 7-year-old spayed female Bouvier des Flandres dog (dog No. 2). Inclusions were pale blue-gray with hematoxylin and eosin stain and formed irregular inclusions, replacing up to approximately 80% of the fiber diameter. Inclusions from dog No. 2 were of non-membrane-bound granular to filamentous material that occasionally formed discrete, elongate electron-dense masses. The features of these inclusions were similar to those of materials previously described as complex polysaccharide, polyglucosan bodies, amylopectin, and Lafora bodies. Evidence for a generalized metabolic disorder was not found in these two dogs, suggesting that storage of complex polysaccharide can occur as a relatively nonspecific response to metabolic alterations in skeletal muscle in a variety of conditions.
