The major categories of neuroendocrine tumors of lung are typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma, and small cell carcinoma. The histologic classification criteria of neuroendocrine tumors are well documented in the "WHO Classification of Tumors" based on mitotic figures and necrosis. Cytologic characteristics of neuroendocrine tumors are trabecular, acinar, and solid arrangement of tumor cells and occasional rosette formation. Nuclear chromatin patterns are characteristically described as "salt and pepper chromatin pattern". Many of cytologic classifications documented in the literature are before the "WHO Classification". In this review, the cytologic features of pulmonary neuroendocrine tumors are documented according to the WHO classification, and recent concepts of neuroendocrine tumors of lung are discussed.

흉선에 발생하는 신경내분비 종양은 매우 드문 질환으로 재발이나 전이가 많아 예후가 좋지 못하다. 절반에서 내분비 증상을 보이며, 이 중 33%에서 쿠싱 증후군을 동반한다. 치료로는 수술적 절제가 우선이며, 방사선 치료나 항암치료는 아직 논란의 여지가 많다. 저자들은 쿠싱 증후군을 동반한 흉선의 신경내분비 종양 2례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Background: Neuroendocrine tumors have widespread and different clinical presentations and prognoses. This study was conducted to assess their survival time and prognostic factors in Iran. Materials and Methods: In a retrospective cohort study, 189 patients diagnosed of having neuroendocrine carcinoma were chosen. The tumor and clinical characteristics of the patients were modeled with a Cox proportional hazard approach. Survival was assessed using Kaplan-Meyer curves. Results: Crude median survival time was 30 months. Women survived longer than men (the median survival time for women was 40 and for men was 24 months). Age (<60 vs >60 years old with hazard ratio (HR) of 2.43, 95% CI 1.3-4.5), primary pathology report (carcinoid vs. others with HR 5.85 cm, 95% CI 2.4-14.3), tumor size cm (for 5-10, HR of 3.1, 95% CI 1.6 and for >10 HR of 8.2, 95% with 95% CI 3.1-21.9), and chemotherapy with single drug (taking vs. not taking with a HR 2.2, 95% CI 1.1-4.8) had significant effects on overall survival of patients. Conclusions: Survival time in patients with neuroendocrine carcinomas is related to demographics, clinical characteristics, tumor histology, and subtype specific treatment.

배경 및 목적: 기관지 유암종은 전체 폐암의 약 2%를 차지하며 전형적 유암종과 이형성 유암종으로 나누어진다. 이형성 유암종은, 신경 내분비성 폐암의 범주에서 양끝을 차지하는, 낮은 악성도의 전형적 유암종과 높은 악성도의 소세포 폐암의 중간형으로 여겨지고 있다. 이형성 유암종의 수술 범위, 수술 후 전신적인 치료의 필요성에 관해서 상반되는 주장이 있다. 이에 본원에서 수술 받은 기관지 유암종 환자들을 대상으로 후향적 연구를 시행하였다. 대상 및 방법: 1990년부터 2000년까지 연세의료원에서 15명의 기관지 유암종 환자가 수술 치료를 받았다. 그중 전형적 유암종이 10명, 이형성 유암종이 5명이었다. 병리학적 진단은 WHO/IASLC(1999)의 기준에 따랐다. 결과: 수술은 전폐 절제술 3예, 폐엽절제술 11예, 구획 절제술 1예였다. 전형적 유암종의 경우 1명(10%)에서 국소 림프절 전이를 보였고, 이형성 유암종의 경우 3명(70%)에서 종격동 림프절 전이를 나타내었다. 수술 후 원격 전이는 전형적 유암종에서는 1명(10%)이었으나, 이형성 유암종에서는 4명(80%)에서 나타났다(p=0.017). 수술 후 5년 생존율은 전형적 유암종에서는 100%인 반면, 이형성 유암종에서는 20%로 통계학적으로 유의하게 전형적 유암종의 생존율이 높았다(p=0.0039). 결론: 이형성 유안종의 경우 진단 당시부터 종격동 림프절 전이가 많고 수술 후 생존율도 낮으므로, 비소세포성 폐암에 준하여 폐엽절제술 이상의 수술을 시행하고 종격동 림프절 전이가 있는 경우에는 수술 후 항암화학 요법이 필요할 것으로 생각된다.

Among medical claims review, decision of malignancy is very important. According to the pathologic report may be ordinary pathway. Some tumors are not completely studied especially malignancy. Wheather malignancy or benign is the important thing in medical claims review. We here disscuss on the debatable tumors such as carcinoid tumor, gastrointestinal stromal tumor (GIST), desmoid tumor, MALToma, and pseudomyxoma peritonei. Another controversial subject in the medical claims review is selection of pathologic report. If the result of the pathologic report is not same in one patient, We prefer the selsection of the report from more professional hospital. We have called this professional hospital l as "third hospital" or 'refferal hospital".

Bronchial carcinoid tumors are relatively uncommon neoplasms that are considered to be malignant tumors of low to intermediate grade. They are classified by pathologic features as typical or atypical carcinoids and have distinctly different prognoses and therapeutic options. Surgery is the treatment of choice in typical and atypical carcinoid tumors but the approach has been changing. Recently, several studies have described experiences using other technologies as adjuncts to bronchoscopic resection, technologies such as laser and cryotherapy with curative intent in endoluminal typical carcinoids. Here we present a case of atypical bronchial carcinoid that was treated with bronchoscopic cryotherapy.

흉선 유암종은 전중격동 종양의 2.5-4%를 차지하는 매우 드문 종양으로 1972년 Rosai와 Higa에 의해 처음 기술되었다. 흉선 유암종은 악성의 임상경과, 조직학적 소견 및 불량한 예후등이 흉선암과 구별되며, 병리학적 진단은 광학 현미경 소견과 조직 생화학 검사 및 전자현미경 소견에 바탕을 둔다. 이 종양은 국소 침범과 다발성 전이가 흔하며, 종양의 절제와 방사선 조사를 치료의 근간으로 한다. 국내에서는 1983년 이 등이 보고한 이례 총 8예가 보고되었으나, 골수를 포함한 다발성 전이는 없었다. 저자들은 이화여자대학교 의과대학 부속병원 내과에서 62세의 남자에서 골수침범 및 폐, 늑막, 심낭, 복부대동맥 주위 임파절 및 피하 임파절 전이로 악성경과를 나타낸 흉선 유암종 1예를 경험하였기에 문헌고찰과 아울러 보고하는 바이다.

Small cell neuroendocrine carcinoma of the uterine cervix is a distinct subtype of cervical cancer that appears analogous to oat cell carcinoma and carcinoid tumors of the lung. It has been assumed to be derived from the neural crest via argyrophilic cells in the normal endocervix. We have recently encountered a case of small cell neuroendocrine carcinoma of the uterine cervix coexisting with adenocarcinoma which was argyrophil negative. A 66-year-old multiparous woman was admitted because of vaginal bleeding for 2 months. Cervicovaginal smear revealed several scattered clusters and sheets of monotonous small cells with some peripheral palisading in the background of hemorrhage and necrosis. Radical hysterectomy specimen revealed an ulcerofungating tumor on endocervical canal which was composed of two components. Major component of the tumor was made up of monomorphic population of small oval-shaped tumor cells arranged in sheets and partly in acinar structures or trabecular fashion. Other component was adenocarcinoma, endocervical well-differentiated type. Argyrophilia was present on the Grimelius stain and immunohistochemical studies revealed diffuse positivity to neuron-specific enolase and carcinoembryonic antigen. Electron microscopic examination showed clusters of small round to oval cells, which had a few well-formed desmosomes and several membrane-bound, dense-core neurosectetory granules.

In case of neoplasm claims, it is important to make a decision of differentiating malignant and benign. In Korean insurance market, there are many insurance products that cover cancer. In the insurance claims adjustment, differentiation between malignant and benign is according to histologic findings. However there are many neoplasms of bad clinical course in spite of benign histopathologic classification. In this article; astrocytoma, thymoma, gastrointestinal stromal tumor, colonic intramucosal carcinoma, gastric high grade adenoma/dysplasia, carcinoid tumor, MALT lymphoma, revision of Korean Classification of Disease-6th edition, and bladder tumors are reviewed in terms of differentiation between malignant and benign in the insurance claims. It may be helpful for claims staff to review important neoplasms in terms of differentiation between malignant and benign.

Paraganglioma is a relatively rare, generally benign and slow growing tumor arising from widely distributed paraganglionic tissue thought to originate from the neural crest. In the head and neck region, paraganglionic tissue is distributed in the superior and inferior paraganglia such as the carotid body, the vagal body, and the jugulotympanic region. Approximately 10% of patients with paraganglioma have a family history of such tumors. Multiple lesions can be found in 26% of patients with family history. It is important to distinguish between paraganglioma and atypical carcinoid tumor and medullary thyroid cancer. This can be done with histopathologic evaluation and immunohistochemical markers. Complete excision is recommended for the treatment of this tumor. Paraganglioma is particularly aggressive and rapid recurrence of paraganglioma is common after local resection. We present a case of malignant paraganglioma in the neck which recurred 2 months after local resection. We suppose that radiation therpay could be the last option for the treatment in this clinical setting.
