Abstract
Juvenile
rhabdomyosarcomas were diagnosed in two young dogs
based on the results of histopathology,
phosphotungstic acid-hematoxylin stain,
immunohistochemistry, and the age of the dogs. One
dog, an 2yrs germanshepard had tumor mass in the
maxillary premolar teeth gingiva . Histologically,
the gingival mass was an alveolar type of
rhabdomyosarcoma . The other dog, a 1.5-year-old
Basset Hound, had alveolar type of rhabdomyosarcoma
involving the premolar to molar teeth region and CT
examination in each case revealed extensive bony
involvement of maxilla .temporal muscles, with
metastasis to the regional lymph node and lungs. A
diagnosis of solid-pattern alveolar rhabdomyosarcoma
was made on the basis of morphologic and
immunohistochemical staining for desmin. Alveolar
rhabdomyosarcoma should be considered in the
differential diagnosis of tumors in juvenile dogs,
especially when cytologic findings reveal round,
undifferentiated cells. Both the cases were
subjected to surgical excision of tumor tissue
followed by chemotherapy. Both the dogs died within
two months of the admission.
