근골격계와 소화기계에 동반된 다발성 원발성 종양은 매우 드물다. 52세 남자 환자에서 전완부의 점액섬유육종과 직장의 선암이 동반된 동시성 이중성 원발성종양이 발견되었다. 환자는 1년전부터 발생한 전완부의 통증 및 부종을 주소로 내원하였다. 전완부의 병변은 조직학적으로 점액섬유육종으로 확진되었다. 전신적 검사상 결장경 검사에서 직장의 선암이 발견되었으며 CT 검사상 폐로의 전이와 심장내 종양이 발견되었다. 병리학적 확정진단 후에 전완부의 수술적 절제술과 술 전,후 항암화학요법을 시행하였으며, 환자는 술 후 2달 후에 종양 색전에 의한 폐동맥혈전색전증으로 사망하였다. 저자들은 매우 드문 근골격계와 소화기계에 동반된 다발성 원발성 종양 1례를 경험하였기에 이를 문헌고찰과 함께 보고하고자 한다.

Purpose: Double primary colorectal cancer (CRC) and gastric cancer (GC) represent the most common multiple primary malignant tumors (MPMT) in Korea. The recognition and screening of hidden malignancies other than the primary cancer are critical. This study aimed to investigate the clinicopathologic characteristics and survival rates in patients with synchronous or metachronous double primary CRC and GC. Methods: Between January 1994 and May 2018, 11,050 patients were diagnosed with CRC (n=5,454) or GC (n=5,596) at Gil Medical Center. MPMT and metastatic malignant tumors were excluded from this study. A total of 103 patients with double primary CRC and GC were divided into two groups: the synchronous group (n=40) and the metachronous group (n=63). The incidence, clinicopathologic characteristics, and survival rate of the two groups were analyzed. Results: The incidence of synchronous and metachronous double primary CRC and GC was 0.93%. Double primary CRC and GC commonly occurred in male patients aged over 60 years with low comorbidities and minimal previous cancer history. There were significant differences between the synchronous and metachronous groups in terms of age, morbidity, and overall survival. Metachronous group patients were 6 years younger on average (P=0.009), had low comorbidities (P=0.008), and showed a higher 5-year overall survival rate (94.8% and 61.3%, P<0.001) in contrast to synchronous group. Conclusion: When primary cancer (CRC or GC) is detected, it is important to be aware of the possibility of the second primary cancer (GC or CRC) development at that time or during follow-up to achieve early detection and better prognosis.

Cytologlc evaluation of cerebrospinal fluid(CSF) is an effective mean for diagnosing many disorders involving the central nervous systems(CNS). One of the most important reasons for cytologic examination of CSF is to detect metastatic or primary neoplasms of the CNS. We did a retrospective study of 1,438 CSF specimens obtained between 1992 and 1996. A total of 1,205 adult and 233 pediatric CSF specimens from 947 patients were accessed at the Department of Pathology of Seoul National University Hospital and Children's Hospital, respectively. Among 1,438 CSF cytology specimens, 169 cases(11.8%, 77 patients) including 135 adult cases(59 patients) and 34 pediatric cases(18 patients) were positive for malignant cells. Diagnoses included 50 metastatic carcinomas(adult, 60; pediatric, 0); 46 malignant lymphomas(adult, 44; pediatric, 2); 21 leukemias(adult, 20; pediatric, 1); 4 retinoblastomas(adult, 0; pediatric 4); 2 rhabdomyosarcomas(adult, 0; pediatric, 2); 1 multiple myeloma(adult, 1; pediatric, 0), and 35 primary CNS neoplasms(adult, 10; pediatric, 25). The most commonly identified metastatic carcinomas in adults were adenocarcinoma. Their primary sites were the lung, gastrointestinal tract, and breast in order of frequency. The most common primary CNS neoplasm in children was medulloblastoma.

소위 다형선종이라 불리는 혼합종은 주로 침샘에 기원하며 폐에서 발생한 예는 세계적으로 보고된 예가 극히 드물다. 이 신생물은 저악성도를 나타내기도 하나 재발이나 원격전이와 같은 공격적인 성향을 보이는 경우도 있다. 우리는 종양의 완전 절제후 병리학적으로 폐의 일차성 악성 다형선종임을 확인하였고 술 후 다발성 전이와 같은 악성 신생물의 소견을 보이는 증례를 경험하여 이를 보고하는 바이다.

다발성 원발성 악성종양은 두개 이상의 암이 동일 개체내에서 각각 독립해서 발생하는 것을 말한다. 저자들은 국내에서는 보고된 바가 없는 폐암, 악성 흉선종 및 방광암이 동반된 3중암 1례를 치험 하였다. 환자는 60세 남자로 호흡 곤란,흉부 불쾌감을 호소하였으며, 3개월전에 방광암 진단하에 Bricker식 수술을 받았다. 당시 시 행한 흉부 단순 사진과 전산화 단층 촬영상 대동맥 전부, 흉골 후부에 종격동 종괴와 폐의 좌하엽 후부에 폐종괴가 보였다. 수술시 좌하엽에서 폐종괴가 촉진되었으며 주위조직으로 이미 침입한흉선종이 발견되어 폐의 좌하엽 절제술및 흉선 절제술을시행하였다. 술후 1차례의 화학요법을 받았으나 더이상의 치료를 거부하고 자의 퇴원하여 약 1년 후에 사망하였다.

Solid pseudopapillary tumor (SPT) of the pancreas is a rare neoplasm with low malignant potential, which has a good prognosis with more than 95% survival at 5 years. Only approximately 10% to 15% cases of SPTs are malignant. This report presents a case of a 38-year-old woman who developed malignant SPT of the pancreas with synchronous multiple hepatic metastases. She underwent a successfully complete surgical resection for multiple hepatic metastatic tumors in addition to primary tumor.

Context: Patients diagnosed with a cancer have a life time risk of developing another de novo malignancy depending on various inherited, environmental and iatrogenic risk factors. Of late the detection of new primary has increased mainly due to refinement in both diagnostic and treatment modalities. Cancer victims are surviving longer and thus are more likely to develop a new metachronous malignancy. Aims: To report our observed trend of increase in prevalence of both synchronous and metachronous second malignant neoplasms among cancer victims and to review the relevant literature. Settings and Design: A hospital based retrospective collection of prospective data of patients diagnosed with second denovo malignancy. Materials and Method: The study was conducted over a 5 year period from July 2008 to June 2012. All patients diagnosed with a histologically proven second malignancy as per Warren Gate's criteria were included. Various details regarding sex, age at presentation, synchronous or metachronous, treatment and outcome were recorded. Conclusions: The occurrence of multiple primary malignancies is not rare. Awareness of the possibility alerts the clinician in evaluation of patients with a known malignancy presenting with unusual sites of metastasis. Individualizing the treatment according to the stages of the primaries will result in durable cancer control particularly in synchronous double malignancy.

흉막의 종괴는 다양한 양성과 악성 종양이 있고 종양은 아니지만 종양 같은 질환들에 의해 발생한다. 일차 흉막 종양에는 고립섬유종양, 악성중피종, 그리고 원발성 흉막 비호지킨 림프종이 있다. 흉막에 발생하는 가장 흔한 종양은 전이성 질환이며, 림프종, 백혈병, 다발성 골수종 등의 혈액 종양을 가진 환자에서 드물게 나타난다. 흉수는 주로 흉막의 악성 질환과 연관이 있다. 드물지만 흉막 종양이 만성 농흉에서 생길 수 있으며, 그중 가장 흔한 것은 비호지킨 림프종이다(농흉과 연관된 림프종). 종양이 아닌 흉막 종괴로는 다양한 양성 질환에서 보일 수 있으며, 여기에는 결핵, 석면 흉막판, 그리고 흉막 유리체가 포함된다. 이 임상화보에서 저자들은 흉막의 다양한 양성과 악성 종양 및 종양성 질환들에 대한 특징적인 전산화단층촬영 소견에 대해 알아보고자 한다.

Plasmacytoma is a plasma cell neoplasm that locally infiltrates a bone or spreads to extramedullary areas. A new World Health Organization criterion defines solitary plasmacytoma of bone as a localized bone tumor consisting of plasma cells identical to those seen in plasma cell myeloma, which is manifested as a solitary osteolytic lesion in a radiological evaluation. Primary tumors of the sternum are generally malignant, and solitary plasmacytomas of the sternum are very rare tumors. We present herein the case of a patient who had a primary sternal tumor with solitary plasmacytoma and no evidence of multiple myeloma.

From May 1965 to December 1990, 78 patients with chest wall tumors were operated on. The mean age of the patients was 31.5 years with 50 male and 28 female patients. Forty-nine cases[62.8%] were developed at bony or cartilaginous wall and 29 cases[37.2%] at soft tissue of chest wall. Thirty-two of them[41.0%] were malignant, either primary or metastatic, and 46 tumors[59.0%] were histologically benign. For 55 patients who were operated on since 1982, 6 surgical biopsies. 39 tumor excisions, and 11 wide excisions with chest wall reconstruction were done. Preoperative factors favoring diagnosis of malignant neoplasm were; 1] old-aged male patient, 2] bone or cartilaginous tumors, 3] involvement of multiple ribs, 4] complaint of pain, 5] large size on palpation[larger than 4cm]. With proper diagnosis and management plan, we think, operations of chest wall tumors can give good results.
