A 13.5kg, 15-year-old male mongrel dog with anemia, anorexia, vomiting and abdominal distension was referred to the Veterinary Medical Center of the Tokyo University. Radiographic and ultrasonographic findings indicated primary splenic tumor. The tumor was located at body of the spleen, which was surgically removed by splenectomy. Histopathological examination of the mass revealed sarcoma type tumor derived from the mesenchymal origin. The patient was in good health after surgery but suddenly showed abdominal distension on the 3 months after. Radiographic findings indicated abdominal neoplasms. The 2nd operation was performed and removed the recurrent mast but suddenly died on the 4th day. Histopathological examination of the tumor was myxosarcoma.

tumors. We report a primary cardiac myxosarcoma in a 40-year-old female patient who was admitted to the hospital because of exertional dyspnea and palpitation. The patient underwent emergency operation immediately after the intracardiac (left atrium) tumor was discovered by an echocardiography. Palliative tumor removal was done and final Pathologic diagnosis was primary cardiac myxosarcoma. She was discharged without complications.

A 6-year-old male Shih tzu dog was presented for evaluation of abdominal distention. Abdominal radiography and ultrasonography revealed a soft tissue density mass containing large amount of fluid. Ultrasonography-guided fine needle aspiration of the mass was performed and cytologic impression was granulation tissue with hematoma and fibroplasias. On exploratory laparotomy a mass was identified at the root of mesentery adhered to distal jejunum. Because the mass could not be separated from the attached jejuna loops, the mass and the adhered sites were surgically removed all together and enteroanastamosis was performed. Histologically a low grade myxosarcoma was diagnosed. Tumor cells were positive with alcian blue stain and Ki67 index by immunohistochemistry was 2.5. The dog recovered from surgery uneventfully, and has been in good condition without any signs of recurrence or metastasis for about 30 months after surgery.

Primary tumors of the chest wall are rare than those of other portions of the body. Soft tissue tumors of the chest wall, though these are benign or malignant, should not be paid special attentions about their management than other soft tissue tumors of the body. Thoracic skeletal tumors, however, have some problems in the treatment because of defect in chest wall leading to herniation of lung and paradoxical movement of thoracic cage. The authors experienced 10 case of primary chest wall tumors at the department of thoracic and cardiovascular surgery, the national medical center, during last 15 years. Five of 10 cases were soft tissue tumors, and they were 2 case of lipoma and each one case of myxosarcoma and leiomyosarcoma. Among 5 bone tumors there no cases of sternal tumor, and their histopathological diagnosis were each one of fibrous dysplasia, giant cell tumor, osteochondroma, Ewing`s sarcoma and osteogenic sarcoma. Wide excision, though it was palliative one in certain case, was performed in 9 cases and only diagnostic incisional biopsy in one case, There were no postoperative deaths during admission to the hospital and all cases were missed during short term follow up after discharge from the hospital.

We describe unusual manifestations of congenital cystic adenomatoid malformation (C.C.A.M.) of the lung, such as movable fungal ball-like intracystic blood clots and hemoptysis, which were detected in previously healthy 23 years-old woman. We identified blood clots only after left upper lobectomy and could not distinguish from fungal ball with radiographic methods. CCAM of the lung, rare and lethal form of congenital pulmonary cystic disease, was initially introduced by Ch, in and Tang in 1949. The histogenesis of this lesion is characterized by polypoid glandular tissue proliferation and overgrowth of mesenchymal elements due to cessation of bronchiolar maturation which occurred in after 16weeks intrauterine period. In 80-95% of reported cases, the lesion was confined to a single lobe and there was no lobe and right and left lung predilection The clinical presentation may be widely variable, ranging from intrauterine fetal death to late discovery in childhood with recurrent pulmonary infection. But there,s no reports which were misdiagnosed with intracystic fungal ball. The treatment choice is lobectomy of affected lobe. There,s a few case reports with rhabdomyosarcoma, bronchiolar cell carcinoma and myxosarcoma arising in CCAM patients. Therefore, early resection is recommended even if asymtomatic cases. We experienced a rare case of CCAM of the lung in 23 years old female, and there were intracystic fungal ball-like movable blood clots in lower portion of left lung. After left upper lobectomy was performed, now she is discharged and followed up without any complications.
