A Cardiac Rhabdomyoma in a Guinea Pig
A guinea pig (9-week-old) that had been placed in a control group for a
pharmacological test was found to have a single nodule on the surface of the
right ventricular wall. In a transverse section of the heart after fixation, a
whitish mass was found that extended from the subendocardium to the
subepicardium of the right ventricular wall. Histopathological examination
revealed a spongy network consisting of vacuolated spaces in the myocardium of
the right ventricle extending to the myocardium and subepicardium of the right
atrium. The vacuolated space was PAS-positive. Immunohistochemical examinations
revealed that the lesions contained striated fibers that were positive for
anti-desmin and anti-myoglobin. Electron micrographs revealed the lesions
resulting in affected striated muscle fibers and accumulations of many glycogen
granules. Based on the findings, the lesions were diagnosed as a cardiac
rhabdomyoma. This is the first report of application of immunohistochemical
examinations to diagnosis of cardiac rhabdomyoma in the guinea pig
