We report a case of multicentric, biatrial cardiac myxoma in a 29-year-old female who complained of exertional dyspnea, abdominal distension and peripheral edema. Any other associated skin lesions, breast mass or endocrine disorder presenting complex form were not seen on her. Also, there was no contributory medical history, hypertension and diabetes mellitus. By using transthoracic echocardiography, we identified a biatrial myxoma attached to the interatrial septum. During surgical excision, we found a large right atrial myxoma with extension through the fossa ovalis into the left atrium and small myxoma attached to the right atrial free wall. After successful resection of interatrial septum and free wall, atrial septal defect was created during the resection and safely repaired by bovine pericardial patch.

OBJECTIVETo discuss the clinical features and treatment options for aggressive angiomyxoma (AAM).

METHODSWe retrospectively analyzed the clinical data of 4 patients with AAM treated at PUMC Hospital from January 1990 to December 2004.

RESULTSThere were 1 man and 3 women with an average age of 34 years. The average age of the female patients were 27 years. Two patients (50%) had urinary or enteric compressive complaints, while another 2 patients had no clinical symptoms. Two patients underwent transvaginal surgeries, 1 patient underwent transabdomenal surgery, and 1 patient underwent subcurtaneouly local excision. Three patients (75%) experienced recurrences after operation and the median relapse time was 2.5 years.

CONCLUSIONSAAM usually occurs in female pelvic cavity and the soft tissues of female perineum. AAM is huge in capacity, and easy to infiltrate or recur locally.

Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a recently described mesenchymal tumor of the stomach. We report the first case of PAMT in Korea. A 52-yr-old man underwent esophagogastroduodenoscopy due to dyspepsia for 2 yr. There was a submucosal mass with small mucosal ulceration in the gastric antrum. The tumor measured 3.5 x 2.3 cm in size and showed multinodular plexiform growth pattern of bland-looking spindle cells separated by an abundant myxoid or fibromyxoid matrix rich in small thin-walled blood vessels. The tumor cells were negative for CD117 (c-KIT), CD34 and S-100 protein, but diffusely positive for smooth muscle actin consistent with predominant myofibroblastic differentiation. The patient is doing well without recurrence or metastasis for 5 months after surgery. Although there have been limited follow-up data, PAMT is regarded as a benign gastric neoplasm with histological and immunohistochemical charateristics distinguished from gastrointestinal stromal tumor and other mesenchymal tumors of the stomach.

Unusual presentation of localized gingival enlargement associated with a subjacent tumoural pathology is reported. The patient was a 55-year-old black male, whose chief complaint was a progressive gingival overgrowth for more than ten years, in the buccal area of the anterior left mandible. According to the clinical features and the radiological diagnosis of odontogenic keratocyst, a conservative surgery with enucleation and curettage was performed. Tissue submitted for histopathological analysis rendered the diagnosis of odontogenic myxoma. After 12-month of follow-up, no evidence of recurrence was found. Clinicians should be cautious when facing any gingival enlargement to avoid diagnostic pitfalls and to indicate the appropriate treatment.

Primary cardiac sarcomas are extremely rare. We report a case of a primary cardiac sarcoma with myxoid change, which originally presented as a benign cardiac myxoma on a two- dimensional echocardiogram. On operating, the mass was found to extend into the posterior left atrial wall, the left pulmonary vein, and the mitral valve. The patient underwent wide resection of the left atrium, a mitral valve replacement and a left pneumonectomy. The histological diagnosis was of an undifferentiated primary cardiac sarcoma. The patient had postoperative chemotherapy. The patient expired 11 months after surgery due to a recurrence of the cardiac sarcoma. Although most tumors that develop in the left atrium are benign myxomas, we should make a preoperative differential diagnosis.
