A case of primary rhabdomyosarcoma in the brain stem is described in an 8 year old girl. The clinical data showed a right side hemiplegia then a total paralysis of the left sixth cranial nerve and a paraplegia which became lethal in 3 months. The necrospy revealed a tumoral nodule in the left medulla oblongata and pons with diffuse subarachnoidal extension from the cranial nerves to the cauda equine roots. Histologically the tumor appeared to be polymorph with numerous rhabdomyoblasts which had a clear cross striation and which were sometimes less differentiated without any neuronal or glial elements. Perivascular tumoral cells and blood vessels were closely linked, the Virchow-Robin spaces were clearly involved. The electron microscopic study confirmed that the less differentiated cells were of a rhabdomyoblastic nature. A review of the litterature indicates that these malignant neoplasias are highly exceptional, and can be classified within the group of primary tumors of the neuraxis with muscular elements. The histogenetic origin of these tumors appears to be the ectomesenchyme of neural crests.

There were 79 cases of cardiac tumors seen from 1957 to July 1988. 49 (62.0%) of them were benign and 30 (38.0%) malignant. All the 49 benign tumors except 2 were surgically excised and found to be myxoma. Of them, 18 patients were male and 31 female. 85.7% of the tumors were located in the left atrium, 12.2% in the right atrium and 2.0% in the left ventricle. Palpitation, dyspnea, chest oppression, fever, episodes of syncope and hemiplegia, cough, diastolic and systolic murmurs at the apical or tricuspid area were the common symptoms and signs. Atrial fibrillation was found only in 2 cases. Echocardiographic findings were diagnostic while ECG and X-ray findings were nonspecific. Four patients died after operation. Of the 30 cases of malignant tumors, 15 were secondary tumors metastasized mainly from the lung or mediastinal malignancies. Of 11 primary tumor cases (7 males and 4 females), 3 were malignant lymphoma, 2 mesothelioma of pericardium, 2 malignant myxoma, 1 angiosarcoma, 1 leiomyosarcoma, 1 fibrosarcoma and 1 rhabdomyosarcoma. Another 4 cases were not studied histopathologically. The clinical manifestations, ECG and X-ray findings of the 11 primary tumors were nonspecific but echocardiography was helpful to the diagnosis. Six patients were operated on and 1 died during hospitalization.

A necropsy case of a primary rhabdomyosarcoma with chronic paragonimiasis in the cerebrum of a 68-year-old man is reported. The clinical data showed a right hemiplegia and dysarthria which became lethal in 6 months even though operation and radiation therapy were performed. Computed tomography revealed a large low-density area associated with the peripheral enhancement in the left basal ganglia, and multiple conglomerated calcified masses in the left temporal and occipital lobes. Biopsied and necropsied materials of the tumor in the basal ganglia was reddish brown in color and histologically was composed of purely mesenchymal derivatives with both embryonal and mature striated muscle cells but neither neuronal nor glial elements. Some of the tumor cells with extending slender cytoplasms showed obvious cross striations at the light and electron microscope levels and immunohistochemical reactivity for myoglobin. All tumor cells were also positive for vimentin, but not for glial fibrillary acidic protein. The clinical and necropsy findings revealed no primary lesion anywhere but in the brain. In addition, numerous dead oval eggs of Paragonimus westermani were found in many cystoid lesions encapsulated by thick connective tissues with calcification and/or ossification. Clinicopathological features of 24 cases of primary rhabdomyosarcoma of the central nervous system reported in the literature are reviewed briefly. The histogenesis of this tumor are discussed together with comments on cerebral paragonimiasis.

Two cases of paratesticular rhabdomyosarcoma were reported. One was a 53-year-old male, who was admitted to the Hospital because of swelling of the scrotum, hemosputa, and complete left hemiplegia. Clinical diagnosis was testicular tumor with remote metastases to lung, brain, liver, and para-aortic lymph nodes. At operation, tumor of 340 g of the paratesticular appendage was removed. Pathological findings of the tumor revealed rhabdomyosarcoma of mixed pleomorphic and embryonal types. The other was a 32-year-old male, who was admitted to the Hospital because of left inguinal and scrotal masses. The patient had a history of bruise at the left inguinal region about 5 years prior to admission. An orchiectomy and an excision of the inguinal tumor were performed. Histologically, the tumor was rhabdomyosarcoma of pleomorphic type. Clinical and pathological features of this rare tumor were discussed with a review of literature.

A primary cerebral rhabdomyosarcoma is reported in a 51-year-old female. She noticed progressive weakness of the left leg in September 1977 and underwent craniotomy for a brain tumor in Tokyo Metropolitan Okubo General Hospital. At the operation the tumor was located on the medial aspect of the right frontal lobe, being attached to the falx. The tumor was 6.0 x 5.0 x 4.0cm in size and subtotally removed. Shortly after operation, she developed a left-sided hemiplegia and was referred to our Kanagawa Rehabilitation Center. During rehabilitation she developed disturbance in recent memory, orientation and speaking. A second operation was done in June 1978, revealing obvious recurrence. A well demarcated extramedullary gray and soft tumor, 7.0 x 5.0 x 3.5cm in size, was found in the previously operated site, being attached to the falx. It was subtotally again. Following surgery her clinical condition was temporally improved. Four months following surgery, however, she developed signs of increased intracranial pressure and died in October 1978 in spite of having chemotherapy and irradiation. Autopsy was not permitted. The tumor was diagnosed as rhabdomyosarcoma with light and electron microscopies and several investigation revealed no primary lesion in elswhere except for the cranium. The histological documentation is also presented and discussed.

A 56-year-old male suffered from primary rhabdomyosarcoma on the left internal thoracic wall, which was treated by chemotherapy, and local irradiation following biopsy. Four months after the diagnosis, he suddenly complained of headache and left paresthesia occurred followed by generalized convulsion and left hemiplegia. CT scan revealed a high density mass in the right parietal lobe. The patient was referred to our department and underwent emergency evacuation of the hematoma together with tumor removal. The pathological specimen showed spindle or oval-like cells with hypercellularity and some mitotic figures. Immunohistochemical study demonstrated that many cells were positive for desmin and myoglobin, which is specific to myogenic tumor. These characteristics were compatible with those of the primary thoracic lesion, and a diagnosis of metastatic rhabdomyosarcoma was made. Five weeks after the craniotomy, the metastatic brain tumor recurred in the same site and also in the bilateral occipital lobes. Although radiotherapy to the brain decreased the tumor size, the patient died of respiratory failure eleven and a half months after the initial diagnosis. Sarcomas metastasizing to the brain are rare and only 16 cases of rhabdomyosarcoma metastasizing to the brain have been reported so far. Recent advances in chemotherapy, however, have been able to show the increased incidence of sarcoma metastasis to the brain. Therefore, the necessity of follow-up CT scan for sarcoma patients of long survival is to be stressed, even if the patient shows no neurological symptoms.
