Undifferentiated pleomorphic sarcoma (UPS) is a high-grade neoplasm that is usually located in the extremities and retroperitoneum. In the past, UPS was considered the most common soft tissue sarcoma in adults; due to improvements in diagnostic techniques, most cases have been reclassified as other lineage-specific tumors. Gnathic bones are rarely affected, and the clinicopathological characteristics of this neoplasm when diagnosed in the jaw remain to be better described. In this report, we present a rare case of mandibular UPS affecting an 88-year-old female who demonstrated a painful swelling on the right side of the mandible that was accompanied by a pathological fracture. Microscopic examination revealed a pleomorphic spindle-cell neoplasm with mitotic figures and necrosis. The patient underwent surgery and adjuvant radiotherapy but experienced metastasis after 12 months of follow-up and died. Diagnosis of UPS is challenging, and oral pathologists must be aware of this entity when dealing with aggressive undifferentiated neoplasms.

이하선에 생기는 전이성 다형태 선종은 매우 드문 질환으로서 조직학적으로는 양성이나 임상적으로는 전이를 일으키는 논쟁의 여지가 많은 병변이다. 저자들은 이하선의 다형성 선종으로 절제술을 경험한 57세 남자에게서, 4년 후에 흉막과 우측 폐, 종격동, 심낭, 늑간근의 다발성 전이를 진단하여 전이암 절제술을 경험하였기에 보고하고자 한다.

신경내분비 종양은 매우 드문 흉선 종양으로, Kultschizky 세포에서 유래하는 것으로 흉선종과는 다른 것으로 생각된다. 흥선 신경내분비 종양의 병리학적 진단은 광학 현미경 검사, 면역조직화학 염색 및 전자현미경의 소견을 바탕으로 한다. 흥선 유암종의 약 50%에서 내분비 질환을 가지며, 재발과 흉곽외 전이가 특징적이다. 초발 종양이나 재발의 경우에 외과적 절제가 가장 효과적이라고 생각되나, 항암치료나 방사선 치료의 역할은 분명하지 않다. 최근 외과적 절제가 시행된 흉선 신경내분비 종양을 경험하였기에 여기에 보고한다.

Although neoplastic involvement of the pericardium is frequently present postmortem, cardiac manifestations before death are uncommon, and cardiac tamponade as the initial presentation of cancer is rare. We are presenting a metastatic pericardial tumor with cardiac tamponade of unknown primary neoplasm. The patient brought to hospital in a state of unconscious. The chest x-ray film showed cardiomegaly with a globular heart shape and right pleural effusion. We underwent an anterior thoracotomy and pericardial window was created. The histopathologic finding of pericardium, pleural and pericardial effusion show a metastatic adenocarcinoma. The patient subsequently received adjuvent radiotherapy and chemotherapy, but he expired on the postoperative 132 day.

From 1973 through June 1993, 25 patients underwent pulmonary resection for pulmonary metastases from carcinoma or sarcoma at our institution. There were 11 carcinomas and 14 sarcomas. 24 patients[96% complete] could follow-up and the median follow-up time was 20 months with a range of 4 months to 271 months and total follow-up period was 1105 months-patients. In our patients, actuarial 5-year survival rate was 49%, mean survival time was 66.6$\pm$12.6 months and median survival time was 84 months. Patients with sarcoma, more than 24 months of the tumor-free interval, postoperative adjuvant therapy had a better survival than did those with carcinoma, less than 24 months of the tumor-free interval, no postoperative adjuvant therapy. But there were no statistical differences between two groups[P>0.05]. This results recommend more aggressive surgical treatment for pulmonary metastases.

Germinoma is a rare central nervous system neoplasm in children and young adults. It is well known that a malignant primary neoplasm can be cured by conventional radiation therapy alone or reduced-volume and field irradiation in combination with chemotherapy. The authors report a very rare case of a pineal germinoma, which was completely disappeared after repeated diagnostic brain computed tomography(CT) with review of pertinent literature. There has been neither tumor recurrence nor metastasis during follow-up period.

폐에 발생하는 점막 표피양 종양은 매우 드물며, 대부분 주로 주기관지에서 발생한다. 증상은 주로 기관 자극이나 폐쇄에 의해 발생된다. 점막 표피양 종양이 원격전이 되는 경우는 흔하지 않다. 치료는 수술적 제거가 원칙이며 예후는 종양의 조직학적 소견과 밀접한 관계가 있다. 저자의 경우 우중엽에 발생한 점막 표피양 종양을 우중엽절제술로 치험하여 양호한 결과를 보였기에 이에 보고하는 바이다.

A rotator cuff tear causes shoulder pain and limits movement of the shoulder joint. A chronic degenerative change or impingement is the reason for a rotator cuff tear. Diagnosis is made based on medical history and, physical and radiological examinations. Other causes of shoulder pain include calcific tendinitis, degenerative arthropathy, joint dislocation, fracture, and primary or metastatic neoplasm. However, metastatic cancer in the shoulder joint is difficult to diagnosis. We experienced a case in which a 46-year-old female patient complained of left shoulder pain and limited joint mobility, and these symptoms were due to metastatic breast cancer in the shoulder.

Endoscopic resection is the established treatment for early gastric cancer in selected patients with negligible risk of lymph node metastasis ('absolute indication'). Based on clinical observations and large pathological databases, expanding indications for endoscopic resection beyond absolute indication has been tried in Japan and Korea. However, controversies exist regarding the safety of treating early gastric cancer beyond absolute indication in terms of pathological evaluation of the resected specimen, definition of expanded indication, discrepancy between pre-endoscopic resection and post-endoscopic resection diagnoses of gastric neoplasm, and the best strategy for cases with non-curative resection. In this brief review, current evidence and clinical experience regarding issues of endoscopic resection beyond absolute indication will be summarized.

Epithelial-myoepithelial carcinoma(EMC) is a rare low grade malignant salivary gland neoplasm that most commonly occurs in the parotid gland but can also arise in minor salivary glands. It is a distinct neoplasm characterized by tubular and solid growth patterns and a dual cell population including an inner larger of cuboidal to columnar epithelial cells which are peripherally bounded by a layer of myoepithelial cells with distinctly clear cytoplasm. The clinical course is characterized by a high incidence of local recurrence and not infrequent distant metastasis. The differential diagnosis included acinic cell tumor, adenoid cystic carcinoma, mucoepidermoid carcinoma, sebaceous carcinoma and pleomorphic adenoma. We report a case of EMC of left parotid gland in a 55-year-old woman.
