폐 과오종은 developmental error에 의해 생기는 양성 종양으로, 드문 질환의 하나이다. 그러나, 폐의 전체 coin lesion의 8%를 차지하고, 호발 연령이 50∼60대이며, 특이한 자각증상도 없고, 흉부 X-선으로만 발견된다는 등의 점에서 악성종양과 감별진단이 어려운 질환이다. 더우기 확진을 위해서는 개흉을 하여 병리조직학적 검사를 하여야 한다는 점에서 중요한 의미를 갖는 질환이다. 저자들은 우측 폐문부에 발생한 과오종 1예를 치험하였기에 증례보고하는 바이다. The origin of the Hamartoma from the Greek words for "error" and "tumor" is credited to Albrecht who in 1904 described a disorganized arrangement of tissues normally present in an organ. The hamartomas are uncommon benign developmental tumor like lesions. Peak incidence of the lesion occurs in the 5th and 6th decade as the carcinoma patient do. The majority of the pulmonary hamartomas have no symptoms and the lesions are detected upon routine roentgenograms of the chest. They contain representatives of the histologic components of bronchi or lung tissue, and cartilage is often the predominant tissue. As the lesion has the slow growing tendancy and peripheral location, it is difficult to render the differential diagnosis from the malignant disease. Therefore, definitive diagnosis is established at thoracotomy and histological diagnosis. A case of surgical experience of pulmonary hamartoma which had all the typical clinical features above mentioned and was reviewed with related literatures.

Hemangiopericytoma is a rare tumor, and especially when it arises in the peritoneal cavity. We present here the case of a 60-year-old woman with an isolated recurrent hemangiopericytoma in the liver. The patient presented to us for evaluation of palpable RUQ mass 7 years after she had undergone her first resection of a malignant hemangiopericytoma arising from the greater omentum. She has been lost to follow up 6 months after the first surgery. Various imaging studies showed a single large liver tumor that was hypervascular, well-capsulated and had central necrosis. She was negative for HBs-Ag and Anti-HCV. Under an impression of the recurrent malignant hemangiopericytoma, a right trisegmentectomy was performed for complete resection of the tumor. The pathological examination confirmed the diagnosis of recurrent hemangiopericytoma. Even though the incidence of hemangiopericytomas is low, malignant hemangiopericytomas have displayed frequent recurrences after long diseasefree periods. A recurrent hemangiopericytoma is not easily detected early during follow-up until it is symptomatic because this tumor has no specific tumor marker and it has diverse sites of recurrence. We think that Positron Emission Tomogram (PET) can be a useful tool for detection of recurrent hemangiopericytoma. We describe herein the clinically relevant information about hemangiopericytomas, and we particulary focus on the features of this tumor after the surgical resection.
