ABSTRACT
Low-grade fibromyxoid sarcoma is a slowly growing soft tissue neoplasm that shows benign histologic features but may have clinical course of malignant disease. It has been reported to occur in the thigh, inguinal area, axilla, shoulder, neck, perineum or buttock. However, there have been few cases of abdominal organ involvement. A 21-year-old woman presented with a large palpable abdominal mass. A 7x4 cm sized round soft tissue tumor at right upper quadrant area was identified by abdominopelvic CT scan. Percutaneous ultrasound-guided biopsy revealed features of spindle cell tumor. On exploration, the tumor originated from transvers colon and was attached to gastrocolic ligament, transverse mesocolon and stomach. The tumor could be dissected with transverse colectomy and partial gastrectomy. The excised tumor, measuring 7x5x5 cm, was well demarcated and appeared as an ovoid mass with firm and myxoid cut surface. She was diagnosed with low-grade fibromyxoid sarcoma arising from transverse colon, and is currently being followed-up without recurrence or metastasis.

Pulmonary artery intimal sarcoma is a rare tumor with no characteristic symptoms. It is frequently misdiagnosed as pulmonary embolism. We report a case of pulmonary artery intimal sarcoma in a 48-year-old man with dyspnea, cough and blood-tinged sputum. He was initially suspected and treated as a pulmonary embolism. Computed tomography of the chest showed filling defects occupying the entire luminal diameter of the right and left pulmonary artery as well as extraluminal extension of the intraluminal mass. Surgical resection of the tumor confirmed pulmonary artery intimal sarcoma. After surgery, he received 8 cycles of combined chemotherapy consisting of doxorubicin and ifosfamide. After 8 cycles, Computed tomography of the chest showed interval regression of the residual tumor. Radiotherapy was done as total 6,000 cGy for 5 weeks, following the 8th chemotherapy. The patient's condition was successfully stabilized with chemotherapy and radiotherapy.

The unicuspid aortic valve is an extremely rare congenital anomaly. It usually presents with aortic stenosis and/or aortic regurgitation. Other cardiovascular complications, such as aortic dilatation and left ventricular hypertrophy can accompany it. Herein, we present a case report of a 50-year-old asymptomatic male patient with unicuspid aortic valve, complicated by ascending aortic aneurysm.

Renal and perirenal abscesses are disease entities caused by infections in or around the kidneys. As imaging modalities have improved in quality and convenience, diagnosing these diseases has become easier. Some cases are refractory to conventional treatment and require surgical correction, although most patients can be cured by antibiotic treatment and percutaneous drainage. We here report the case of a patient with a perirenal abscess that recurred twice after appropriate antibiotic treatment and percutaneous drainage. Although Gram-negative bacilli are the most common pathogenic cause of these diseases, we isolated methicillin-resistant Staphylococcus aureus and Mycobacterium tuberculosis in our patient. Thus, poor responses to appropriate treatment in patients with a perirenal abscess can result not only from antimicrobial resistance or a co-infection but also from the 2 conditions existing concomitantly.
