An example of lymphoblastic lymphosarcoma was diagnosed in a 7-year-old male brown bear (Ursus arctos) that died after having a 7-month history of depression, anorexia and watery diarrhea. Grossly the mesenteric lymph nodes were enlarged to approximately 4 to 6 times their normal size and histologically diagnosed as lymphoblastic lymphosarcoma. The small intestinal mucosa was corrugated and had severe mural thickening due to infiltrated neoplastic cells. Hepatic metastasis was also noted. the mother of this bear which died at the age of 20 also had similar gross changes on necropsy, but histological examination was not performed at that time and therefore the exact type of neoplasm remained to be determined. Since the daughter also died of neoplasm, genetic factor could be suspected in this family. This is the first reported case of lymphosarcoma in Ursidae in Korea. As an incidental finding, endogenous lipid pneumonia was noted in the lung.

The most common cause of treatment failure in oral cavity cancer is when it is found to have local recurrence, usually occurring in the ipsilateral cervical lymph node. On the contrary, it is extremely rare to find local recurrence in soft tissue metastasis (STM) in the contralateral neck. Furthermore, lung cancer and malignant lymphoma are most commonly confined to their primary sites. The poor general condition increases the likelihood of STM, which indicates bad prognosis. A 72-year-old man with a hard and fixed mass on the right submandibular space visited our clinic. He had received a wide excision with local flapreconstruction for squamous cell carcinoma in the left corner of lower lip 18 months ago. We performed the wide excision with bilateral selective neck dissection (I-III), and he was finally diagnosed as STM from contralateral lip cancer. We report this unique and rare disease entity with a literature review.

Oncocytic neoplasm of the head and neck region accounts for approximately 1% of all salivary gland tumors, but only 5% of oncocytic neoplasm is malignant. Oncocytic carcinoma arising in the submandibular gland is exceedingly rare. We encountered a sixty seven-year-old male patient who presented with multiple mass in the right neck. Fine needle aspiration biopsy revealed a salivary gland tumor of predominantly oncocytic form, and a differential diagnosis included oncocytic adenoma or mucoepidermoid carcinoma. A right submandibular gland resection and modified radical neck dissection were performed. Histologically, the tumor cells showed nuclear pleomorphism, and stromal invasion, which were compatible with oncocytic carcinoma. After surgery, the entire neck region was irradiated. Seventeen months after the initial surgery, multiple metastases to the bone and lung were detected from the incidental pathologic bone fracture of the right humerus; palliative chemotherapy was performed to resolve this. We report a case of oncocytic carcinoma in the submandibular gland with a review of literature.

Background: Photodynamic therapy (PDT) is effective in managing small superficial early lung cancer patients who were deemed nonsurgical candidates. However, we do not have any previous report on the usefulness of PDT in early lung cancer in South Korea. Thus we report here our experience of PDT in early lung cancer patients. Methods: 10 patients who underwent PDT for managing early lung cancer between June 2006 and July 2010 were analyzed. PDT was carried out 48 hours after photosensitizer injection. Re-bronchoscopy was carried out 48 hours after PDT in order to remove a necrotic tissue from the PDT site. For evaluation of PDT response, bronchoscopy and chest computed tomography (CT) were performed after 3 months. Results: The median age of patients was 69 (49~77) and all patients were male. The smoking history of patients was 48 (20~75) pack-year and the median follow up of patients was 25 (11~52) months. Complete remission was observed in 10 patients and the recurrence of lung cancer was observed in 3 patients. Out of 10 patients, 3 patients died (one case of lung cancer progression and two cases of pneumonia). Conclusion: The PDT is a safe and effective treatment in early lung cancer patients who are not suitable for surgical resection. The PDT in clinical practice is an attractive option in the treatment of early lung cancer.

Objectives: This study aimed to ascertain what should be considered in the "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer" by analyzing the existing guidelines and clinical trials. Methods: The committee searched guidelines and clinical trials about herbal medicine for lung cancer. The searched trials were analyzed in terms of inclusion and exclusion of participants, intervention, comparator, outcomes and trial design. Then, we compared the results of our analysis with the guidelines to identify the issues we will have to consider when making the "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer". Several guidelines for anti-tumor agents and clinical trials with herbal medicine were searched on the national institution homepage. The search terms were as follows: 'lung neoplasm', 'herbal medicine', 'Medicine, Korean traditional', 'Medicine, Chinese Traditional' etc. Results: There was no guideline for clinical trial with herbal medicine for lung cancer. In addition, 7 articles were searched through database searching. All the participants had non-small cell lung cancer. The type of intervention was decoction. Comparators included conventional treatments such as chemotherapy. The outcome measurements used in the studies were quality of life, tumor response, and survival duration, etc. Safety was evaluated by recording adverse events and blood test. Conclusions: Findings were made by reviewing existing guidelines and comparing them with clinical trials for lung cancer and herbal medicinal products. These results will be utilized in the development of "Guideline for Clinical Trials with Herbal Medicinal Products for Lung Cancer".

흉벽에 발생하는 전이성 악성 종양은 드문 질환이며 주위 장기로부터 전이되는 경우가 대부분으로 유방, 폐, 흉막, 그리고 종격동 등으로부터 주로 전이되는 것으로 알려져 있다. 특히 흉부가 아닌 먼장기로부터 전이되는 경우는 더욱 드문 것으로 알려져 있고 원발성 악성 종양이 없이 흉벽 전이에 의해 발현되는 예는 몇몇의 보고만이 있을 뿐이다. 환자는 51세 남자로 전흉벽 좌상부에 촉지되는 종괴로 절제 수술을 시행 후 전이성 간세포암종으로 진단 받았고 당시 검사상 간에 원발성 간세포암종의 증거는 없는 상태였다. 이에 원발성 종양의 증거 없이 간세포암이 흉벽으로 전이된 예를 치험하였기에 보고하는 바이다.

폐전이 골 연부조직 육종에 대한 폐절제 및 합병치료의 성적을 분석하였다. 1986년부터 1996년까지 14례 (남자 11례, 여자 3례)에서 15회의 폐절제술을 시행하였는데, 1례에서는 폐전이 육종의 재발로 2회의 폐절제술을 시행하였다. 절제된 폐전이 육종의 수는 1∼5개였다. 폐전이 육종의 병리조직학적 소견상 4례는 골육종 이었으며, 10례는 연부조직 육종이었다 폐절제술후 평균 생존기간은 29.2개월이었으며, Kaplan-Meier식에 의 한 5년생존율은 33.2%였다. 14례중 3례의 종양 자유기간이 3년이상으로 평균 생존기간은 52.6개월이었으며, 3년 이하의 11례는 추적기간중 모두 사망하여 이들의 평균 생존기간은 17.3개월이었다. 결론적으로 폐전이 육종에 대한 폐절제술은 뚜렷한 수명 연장 효과가 있을 것으로 생각된다.

고립성 섬유성 종양은 주로 흉막에서 발생하는 드문 종양으로 중피하 중간엽에서 기원하며 드물게 흉막 외에서 발생하기도 한다. 많은 경우에서 증상이 없이 우연히 발견되나 다른 중요 장기를 침범하거나 종양의 크기가 커질 경우 증상이 나타나기도 한다. 일반적으로 진단은 영상의학적 검사와 세침흡인을 통한 생검으로 하며 면역조직화학검사를 시행하여 더 정확히 판별할 수 있다 대부분의 경우 양성의 경과를 보이며 병변의 완전한 제거 여부가 가장 중요한 예후 인자가 된다고 알려져 있다. 저자들은 우하엽에 발생한 폐실질 내에 생긴 고립성 섬유성 종양을 채기 절제술로 치험하여 이에 보고하는 바이다

다발성 원발성 악성종양은 최근 발생 빈도가 증가하고 있으며 이는 암의 진단 방법의 개선 및 인구의 고령화, 유해물질에 대한 노출증가에 기인한다. 국내에서도 다발성 원발성 악성종양에 대한 연구가 진행되어왔으며, 김등, 윤등이 보고하였다. 그러나 삼중복암의 발생하는 빈도는 매우 낮은 것으로 보고되어있다. 저자들은 이화여대 동대문 병원 내과에 입원한 다발성 원발성 위암, 후두암, 폐암 환자의 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
