췌장에 생기는 종양 중에 adenosquamous carcinoma는 드물지만, 예후가 좋지 않으며 더 흔한 adenocarcinoma보다 다른 곳으로 전이할 확률이 높다. 이 증례 보고는 pancreas에 생긴 adenosquamous cell carcinoma와 liver로 전이한 병변이 서로 다른 영상소견을 보이는 드문 예로, 기존의 문헌들을 참고해 pancreas에 생기는 드문 질병인 adenosquamous cell carcinoma에 대한 이해를 돕기 위함이다.

Adenosquamous carcinoma of the lung is a rare disease entity and its clinical characteristics, treatment, and prognosis are poorly described. Stage I disease are amenable to operation as in bronchogenic carcinoma of non-small cell type, but stage III adenosquamous carcinoma shows highly aggressive behavior with rapid progression. We have experienced a case of stage III adenosquamous carcinoma of the lung in a 38-year-old male with a large mass in the right upper lobe with multiple metastasis in the mediastinal lymph nodes. Interestingly, all of the metastatic lymph nodes proved to be adenous component histologically. After right pneumonectomy and extensive lymph node dissection, the patient had received one cycle of chemotherapy. However, clinical signs of distant metastasis to bone and brain were discovered within 5 months postoperatively.

Fine needle aspiration (FNA) cytological examination is an appropriate method for the evaluation of pulmonary nodules. In major types of lung cancer, Its diagnostic accuracy is quite high. However, it is sometimes difficult, using this technique, to differentiate between some unusual phenotypes including adenosquamous carcinoma, bronchioloalveolar carcinoma (BAC), neuroendocrine tumor, mucoepidermoid carcinoma, and sclerosing hemangioma. Here, we present a case involving extremely well differentiated adenosquamous carcinoma, mimicking benign lesions, such as pulmonary scar and adenomatoid malformation with squamous metaplasia. The patient was a 68-year-old man presenting with a solitary pulmonary nodule$(1.6\times1.6cm)$, which was incidentally found at the periphery of the right lower lobe. FNA revealed some clusters of glandular cells with minimal atypia, in addition to squamous cells at a nearly full maturational state. Histological examination verified the cytological diagnosis on a lobectomy specimen. The tumor exhibited a well differentiated adenocarcinoma component, mimicking the bronchioles in scarred lung tissue. and a well differentiated squamous cell carcinoma component, mimucking the squamous cell nests of adenoacanthoma, in the other organs. In the present case, the possibility of adenosquamous carcinoma should have been considered if squamous cells were seen in the FNA from the peripheral pulmonary nodule, even though they appeared to be benign.

Background: This study used receiver operating characteristic curve to analyze Surveillance, Epidemiology and End Results (SEER) adenosquamous carcinoma data to identify predictive models and potential disparities in outcome. Materials and Methods: This study analyzed socio-economic, staging and treatment factors available in the SEER database for adenosquamous carcinoma. For the risk modeling, each factor was fitted by a generalized linear model to predict the cause specific survival. An area under the receiver operating characteristic curve (ROC) was computed. Similar strata were combined to construct the most parsimonious models. Results: A total of 20,712 patients diagnosed from 1973 to 2009 were included in this study. The mean follow up time (S.D.) was 54.2 (78.4) months. Some 2/3 of the patients were female. The mean (S.D.) age was 63 (13.8) years. SEER stage was the most predictive factor of outcome (ROC area of 0.71). 13.9% of the patients were un-staged and had risk of cause specific death of 61.3% that was higher than the 45.3% risk for the regional disease and lower than the 70.3% for metastatic disease. Sex, site, radiotherapy, and surgery had ROC areas of about 0.55-0.65. Rural residence and race contributed to socioeconomic disparity for treatment outcome. Radiotherapy was underused even with localized and regional stages when the intent was curative. This under use was most pronounced in older patients. Conclusions: Anatomic stage was predictive and useful in treatment selection. Under-staging may have contributed to poor outcome.

Adenosquamous carcinoma (ASC) of the larynx is very rare malignancy which has well defined two distinctive pathological features, an adenocarcinoma and a squamous cell carcinoma (SCC). Diagnosis of ASC by endoscopic biopsy is challenging due to small amount of harvested tissue. ASC has a worse prognosis than SCC with an early lymph node metastasis and a distant dissemination. We experienced a rare case of vocal fold ASC which was initially misdiagnosed as atypical squamous cell proliferation at frozen biopsy. We reported this case with a literature review.

One case of an unusual form of carcinoma involving the submucosal gland and duct of tongue was reported and reviewed. According to Gerughty et al(1968) four distinct component parts were classified : ductal carcinoma in situ(involvement of the ductal epithelium by in situ carcinomatous changes), squamous cell carcinoma, and a mixed carcinoma(combination of glandular and squamous characteristics and occasionally consisted of large nests composed of "glassy" cell). This tumor was fond to be extremely aggressive and highly malignant. The histopathologic features and the clinical behavior of this tumor were sufficiently distinctive to warrant the designation adenosquamous carcinoma : exhibit concomitant glandular and squamous neoplasm. The mode of therapy was evaluated and the treatment of choice appears to be radical surgery. So, we has done the radical neck dissection and partial glossectomy. However, the limited number of cases indicated that collection and subsequent analysis of additional cases must be performed before any definitive conclusion can be drawn.

10년령의 잡종견이 2개월 전부터 지속적인 기침, 혈액성 비루 및 개구호홉을 주증으로 내원하였으며 혈액검사, 두부 X-ray촬영 및 두부 MRI촬영을 실시한 결과 빈혈소견과 함께 MRI 촬영에서 두개내강으로 파급되지 않은 비강종양으로 추정되는 큰 mass가 비강쪽에서 발견되었다. 그러나 축주의 요청에 의해 이틀 후 안락사하여 부검 후, 병리조직 검사를 실시한 결과 비강 선편평세포암종임을 확인하였다. 본 증례를 통하여 비강종양과 같이 두경부 병변에 있어서 자기공명영상진단법(MRI)은 고전적 방사선학적 검사법에 비교하여 종괴의 침습성과 파급정도를 정확히 평가함으로써 치료방향의 설정과 그 예후를 평가함에 있어 뛰어난 검사법임을 확인할 수 있었다.

Lung cancer is one of the most disastrous of all the current cancers in Korea. In 1990 it was projected that there would be 5, 500 new lung cancer patients in Korea and that 5, 000 would die of their disease. This is a mortality rate of 91 percent. We reviewed the surgically treated 153 bronchogenic cancer patients from January 1987 to December 1991 in St. Mary`s Hospital of Catholic University Medical College. There were 121 men and 32 women ranging in age from 18 to 83 years, with a mean of 56 years. Of the 153 patients, resection was possible in 138 patients and the resectability was 90.1 percent. Squamous cell carcinoma was present in 48 percent of patients, adenocarcinoma in 29 percent, adenosquamous carcinoma in 7 percent, large cell carcinoma in 6 percent, salivary gland tumor in 5 percent, and small cell carcinoma and carcinoid in 3 percent respectively. Postoperative cancer staging was grouped stage I 33 percent, stage II 21 percent, stage IIIa 35 percent, and stage IIIb 10 percent. Lobectomy was performed in 70 percent, pneumonectomy in 17 percent, and segmentectomy in 14 percent. Three and 5-year postoperative survival in resectable 138 patients were 47 and 29 percent respectively.

Glassy cell carcinoma is an unusual neoplasm of the uterine cervix that accounts for $1{\sim}2%$ of all cervical malignancy. It is a rapidly progressive and biologically aggressive disease with poor response to therapy. This tumor is considered to be a poorly differentiated mixed adenosquamous carcinoma. The cytologic findings are characterized by tumor cells arranged predominantly in syncytial like aggregates and an inflammatory background. The tumor cells have moderate amounts of eosinophilic or amphophilic cytoplasm, which is often finely granular. The nuclei are relatively large and have fine chromatin with prominent eosinophilic nucleoli. Cytologically, glassy cell carcinoma is most likely to be confused with large cell nonkeratinizing squamous cell carcinoma and with atypical reparative cells. Herein, we report three cases of glassy cell carcinoma of the uterine cervix diagnosed by cervicovaginal smear and confirmed by histologic section with review of literatures.
