  • 한 환자에서 두개 이상의 중복암이 발생하는 경우는 매우 드물게 알려져 왔으나 근래에 들어와 치료법의 발달로 환자의 수명이 연장되고 진단법이 발달되면서 그 보고가 증가되고 또한 관심도 높아지고 있는 상태이다. 따라서 이런 중복암을 가진 환자의 특성을 분석함으로써 발생할 수 있는 2차 3차 암의 조기 발견 및 나아가서는 발암 물질과 유전적 요인 등을 찾아 암의 치료 및 예방에 이응 할 수 있겠다. 이에 $1978.7\~1986.8$까지 8년간 서울 대학교 병원에서 중복암으로 진단되어 치료받은 121예를 대상으로 하여 다음과 같은 결과를 얻었다. 전체 발생율은$0.7\%$이 있으며 이중 2중복암이 119례, 3중복암이 2례 있었다. 동시성은 (6개월 이내) 51례, 속발성은 (6개월 이상) 70례이었으며 속발성의 경우 $70\%$이상에서 3년내에 2차 암이 발생했다. Moertel분류에 의한 mvlticentriz은 $11.6\%$로 다소 낮은 빈도를 보였으며 다른 장기에 발생한 중복암 중에서는 위암과 간암, 위암과 직장암의 빈도가 가장 높았다.

  • Nevus sebaceous of Jadassohn is a congenital cutaneous hamartoma with epidermal, sebaceous, follicular, and apocrine structures that usually appears at birth or in early childhood. It has the potential to generate a variety of secondary neoplasms of different lineages, and the risk increases with patient age. Although multiple neoplasms may occasionally arise within the same lesion, the coexistence of more than five secondary tumors is extremely rare. Here we report a case of seven secondary tumors including syringocystadenoma papilliferum, desmoplastic trichilemmoma, sebaceoma, trichoblastoma, pigmented trichoblastoma, sebaceous adenoma, and tumor of follicular infundibulum arising within a nevus sebaceous. The complete diagnosis relies on the histopathological analysis of multipoint biopsies and delicate pathological sections.

  • Myopericytoma is a benign tumor that is composed of myoid-appearing oval to spindle-shaped cells with a concentric perivascular pattern of growth. The tumor is morphologically heterogeneous and can exhibit a broad histologic spectrum. We describe a case of multiple myopericytoma occurring in the head and neck skin region with involvement of the parotid gland where it is known to occur very rarely. A 40-year-old woman noticed multiple enlarging, painless, round-shaped masses on her left cheek. The patient had experienced a similar lesion of the same area 8 years earlier which was completely excised and the pathological diagnosis was spindle cell type myoepithelioma. On a computed tomographic image, one mass involved the superficial parotid gland and was well encapsulated. Excision of the facial masses and superficial parotidectomy with facial nerve preservation were performed. A diagnosis of myopericytoma was established in light of the immunohistochemical pattern with the histopathological findings. Over the 4-year follow-up period, there was no evidence of recurrence. As many perivascular myoid neoplasms share common morphologic features with myopericytoma, we should consider the differential diagnosis, and confirm the histological findings with appropriate immunohistochemical staining. After identifying myopericytoma, it should be treated with wide surgical excision to prevent local recurrence.

  • A 71-year-old male patient visited Yeungnam University Hospital with abnormal chest computed tomography (CT) findings. Chest CT revealed multiple lung nodules and a posterior mediastinal tumor, the diagnosis of which was confirmed surgically. Magnetic resonance imaging (MRI) of the abdomen showed multiple small nodules, which were diagnosed as cavernous hemangioma in the liver based on the pathology results of the mediastinal and lung masses in combination with MRI findings. Cavernous hemangiomas are benign tumors that can occur throughout the body, mainly in the skin and subcutaneous tissue. The liver is the most common internal organ containing hemangiomas, whereas they are very rarely found in the lungs or mediastinum.

  • Purpose: This study aimed to investigate the correlation between multiple early gastric cancer (MEGC) and multiple primary malignancies during the follow-up of patients with gastrectomy. Materials and Methods: The number of primary tumors detected in other organs after gastrectomy for early gastric cancer (EGC) has been increasing because of improved survival and surveillance programs. A total of 3,129 patients underwent radical gastrectomy for treatment of EGC at Samsung Medical Center from January 2000 to December 2005. Of these, 3,057 patients were selected and their medical records were retrospectively analyzed. Results: Among the 3,057 patients, 148 (4.8%) had MEGC, 84.5% were male, 57.4% were over 60 years old, 42.6% had a macroscopic type EGC IIb main lesion, and 68.9% had well-differentiated tumors with a significantly high incidence of MEGC. There were no differences between patients with solitary early gastric cancer (SEGC) and those with MEGC with regard to overall survival or recurrence-free survival, but MEGC was an independent risk factor for metachronous primary malignancies in other organs (P=0.004, hazard ratio [HR]=2.444). Conclusions: MEGC is not a risk factor for poor prognosis after curative gastrectomy, but it is a risk factor for metachronous primary malignancies in other organs during postoperative follow-up; therefore, careful surveillance is needed.

  • Plasma cell neoplasms are generally categorized into four groups; multiple myeloma(MM), solitary plasmacytoma of the bone(SPB), plasma cell leukemias, and extramedullary plasmacytomas(EMP). These tumors may be further described as localized or diffuse in presentation. Localized plasma cell neoplasms are rare occurrences and include solitary plasmacytomas of the skeletal system, which account for 2-5% of all plasma cell neoplasms and extramedullary plasmacytomas of the soft tissue, which account for approximately 3% of all such neoplasms. A plasmacytoma is defined as any discrete, most likely solitary mass of neoplastic plasma cells either in the bone marrow or in various soft tissue sites. Diffuse lesions include the other two groups, multiple myeloma and plasma cell leukemia. The relationship between these processes has not yet been definitively characterized, but there appears to be a continuum in which both SPB and EMP often progress to MM. The patient was referred who had continuous deep throbbing bone pain and swelling on the left posterior gingival area of the mandible after extraction of the first and second molar. The result of intraoperative excisional biopsy of the lesion was confirmed as a plasmacytoma. And it revealed systemic multiple myeloma through the further diagnostic work-up. It is worth to report because of a rare case of multiple myeloma found in oral cavity as a form of plasmacytoma.

  • 본 연구는 항암화학요법을 받는 폐암환자의 불확실성과 불확실성 영향요인을 파악하기 위한 서술적 상관관계 연구이다. 연구 대상자는 일 대학병원에서 항암화학요법을 받고 있는 폐암환자 111명을 대상으로 하였다. 자료는 2014년 7월 25일부터 12월 31일까지 수집하였다. 수집된 자료는 SPSS Window 18.0 Program을 이용하였고, 빈도와 백분율, 평균과 표준편차, t-test, ANOVA, Scheffe test, median, standard deviations, Pearson's product moment correlation coefficient와 multiple regression analysis로 분석하였다. 연구 결과 항암화학요법을 받는 폐암환자의 불확실성은 평균 평점 2.61(${\pm}0.46$)점으로 다른 질병을 가진 환자의 불확실성 정도보다 높았다. 항암화학요법을 받는 폐암환자의 불확실성과 질병의 심각성, 증상의 일관성, 사건의 친숙성, 의료인에 대한 신뢰, 일상 활동 능력, 자기 효능감, 사회적 지지와의 관계를 분석한 결과 불확실성과 질병의 심각성 간의 상관계수는 .74(<.01), 불확실성과 증상의 일관성 간의 상관관계는 .27(<.01)이었다. 질병에 대한 심각성이 불확실성에 가장 영향을 미치는 변수로 나타났으며, 전체 설명력은 54%이었다. 이상에서 항암화학요법을 받는 폐암환자의 불확실성을 감소시키기 위한 간호중재가 필요할 뿐만 아니라 폐암 환자의 간호중재에는 질병의 심각성을 고려한 간호중재가 이루어져야 할 것이다.

  • 다발성 원발성 악성 종양은 한 환자에서 2개 이상의 원발성 악성 종양이 각각 독립적으로 발생하는 경우를 말한다. 저자들은 78세 남자 환자에서 동시에 발생한 유방의 점액성 선암과 유방외 림프종의 증례를 경험하여 보고하고자 한다. 환자는 2개의 만져지는 덩이를 주소로 내원하여 외과적 생검을 통해 좌측 유방의 점액성 선암과 우측 서혜부의 미만성 거대 B세포 림프종을 확진하였다. 이후 수술 전 시행한 PET/CT에서 좌측 혀편도의 우연종이 발견되었고, 절제 생검을 통해 미만성 거대 B세포 림프종을 확진하였다. 유방암 환자에서 불특정한 림프절 비대가 발견되는 경우 전이성 병변으로 간주되기 쉬우나, 이 증례의 환자와 같이 고령의 환자군에서는 림프종을 감별 진단으로 함께 고려함으로써 오진 및 치료 지연을 방지할 수 있을 것이다.

  • This review summarizes the epidemiology of cancer of the female reproductive system and associated lifestyle factors. It also assesses the available evidence for occupational factors associated with these cancers. Cervical, endometrial, and ovarian cancers are relatively common, and cause significant cancer morbidity and mortality worldwide, whereas vulvar, vaginal, fallopian tube cancers, and choriocarcinomas are very rare. As several lifestyle factors are known to play a major role in the etiology of these cancers, very few published studies have investigated possible relationships with occupational factors. Some occupational exposures have been associated with increased risks of these cancers, but apart from the available evidence on the relationships between asbestos fibers and ovarian cancer, and tetrachloroethylene and cervical cancer, the data is rather scarce. Given the multifactorial nature of cancers of the female reproductive system, it is of the utmost importance to conduct occupational studies that will gather detailed data on potential individual confounding factors, in particular reproductive history and other factors that influence the body's hormonal environment, together with information on socio-economic status and lifestyle factors, including physical activity from multiple sources. Studies on the mechanisms of carcinogenesis in the female reproductive organs are also needed in order to elucidate the possible role of chemical exposures in the development of these cancers.
