  • Background and Objective : Papillary thyroid microcarcinoma(PTMC) is known as slow growing cancer with good prognosis. However, extrathyroidal extension may increase the risk of cervical lymph node metastasis and local invasion to surrounding structures. The aim of this study was to assess the characteristic features of the tumor invading the posterior thyroid capsule. Material and Methods : We made a retrospective review of 123 PTMC patients with thyroid capsule invasion, pathologically staged as T3 or T4. 74 patients (60.2%) had invasion to posterior thyroid capsule (group A) while 49 patients (39.8%) had invasion to-anterior thyroid capsule or anterior wall of trachea (group B). We assessed the clinicopathologic factors of the patients according to the location of capsular invasion of PTMC. Results : There was no difference regarding age, gender, T and N classification and incidence of lymph node metastasis between two groups. Local invasion rate to recurrent laryngeal nerve was 6.8% in patients with posterior thyroid capsule invasion, while the incidence was zero in those with capsular invasion to other locations Conclusion : Increased risk of local invasion to the recurrent laryngeal nerve should be considered in patients with PTMC presenting invasion of the posterior capsule.

  • Compared to Early Chosun Dynasty, the spatial structure of most local Eupseongs of Korea had a standardized change with the expansion and spread of the Rye-hak(禮學:a study of confucius Rite). Meanwhile in the process of rebuilding Eupseongs there was a tendency of relocation of the local government offices(官衙) and its attached facilities in terms of functions and use. Although it was PyeongSanseong Miryang Eupseong had an unreasonable spatial structure locating Gaeksa(客舍; accommodation house for visitors) in the middle of the local government office complex, and Dongheon(東軒;main office building) in the east of it before the Japanese Invasion of Korea in 1592. However with the reorganization of spatial Structure of local Eupseongs after the Japanese invasion Gaeksa was moved to the foot of Adongsan where commanded a fine view of river. Dongheon was moved to the center of Eupseong for the effective management of its auxiliary organizations. It was because road system and administrative efficiency had a serious effect on deciding the location of the local government office and its attached facilities. After the Japanese invasion Hyangchoeng(鄕廳), having been out of Eupseong, also was moved to the independent location within Eupseong separate from Dongheon and Gaeksa. It seemed to take into account the autonomy of Hyangchoeng. Dongheon, Gaeksa, and Hyangchoeng which are the crucial facilities of Milyang Eupseong were arranged at each angular point of big triangle. In order to enhance the administative efficiency, the attached administrative facilities were arranged surrounding Dongheon and Hyangchoeng. The spatial structure of Milyang Eupseong in the late Choseon dynasty was of great difference from that of uniformly organized system of early Choseon Period. It was because the development of administrative function, the pursuit of efficiency, and commercial progress had a great impact on the change of urban space.

  • This study collected and intensively analyzed the works and remains in Namwon(南原) province by Liu Ting(劉綎) of Ming Dynasty during the Imjin War (the Japanese invasion in 1592-1598; 壬辰倭亂). Liu Ting engraved characters on the rocks as passing by the Yeowon hill(女院峙) twice. A local official of Namwon built a memorial stone at the guest residence of Namwon district to appreciate the contribution of Liu Ting to care for the local people. During the second Japanese invasion in 1597-1598(丁酉再亂), Liu Ting often climbed up the Yongdu pavilion(龍頭亭) located at Mt. Yongtu(龍鬪山) and fell in love with the splendid scenery while enjoying fishing at Jogi(釣磯). Immediately after the war, Liu Ting renovated the Guanwang Shrine(關王廟) in Namwon and built the memorial stone claiming that he defeated the Japanese army with the divine power from Guanyu(關羽).

  • Overexpression of several aquaporins (AQPS) has been reported in different types of human cancer but roles in human carcinogenesis have yet to be clearly defined. Here, we up-regulated expression of the AQP8 gene in SiHa human cervical cancer cells with a lentivirus transfection system and investigated its effects as a potential therapeutic target for cervical cancer. Results showed AQP8 overexpression did not affect their substrate adherence and proliferation, but accelerated migration as assessed by transwell migration and wound healing assays. Moreover, AQP8 overexpression significantly enhanced local invasion of SiHa cells in nude mice. These findings altogether indicate that AQP8 overexpression increases migration of SiHa cells and probably participates in the process of tumor local invasion.

  • Purpose: Dermatofibrosarcoma protuberans(DFSP) is a moderate - degree malignant tumor of soft tissue from dermis to fat layer with high recurrences(11% to 73%) due to its local infiltrative characteristic. Many debates and controversies in deciding accurate surgical margin were presented before, but references about depth of invasion and appropriate surgical excision level were not properly made out. Therefore, we tried to identify the degree of tissue invasion of DFSP. Methods: Twenty patients, including 8 patients with recurrent lesions, over last 10 years were reviewed retrospectively. Different surgical margins were applied according to the location and based on histopathologic result, we have defined as a 'deep tissue invasion' if there were infiltration of tumor cell into fascia or underlying muscle layer was present. All invaded tissue including dermis, fat, fascia and muscle were excised until no tumor cell was found during intraoperative frozen section biopsy. And comparative analysis of deep tissue invasion according to age, primary site, duration of disease and recurrence was done. Results: Thirteen patients(65%) showed deep tissue invasion and incidence was found to be increasing with age(over 30 years old). All patients with DFSP on head and neck region revealed deep tissue invasion followed by trunk(54%) and lower extremities(50%). There was no relationship between duration of disease and deep tissue invasion. Conclusions: It is clear that many cases of DFSP had a deep tissue invasion. And high prevalence of deep tissue invasion with age, primary site was intimately associated. So, underlying deep tissue must be completely examined and excised sufficiently throughout the operation for clear resection of DFSP with no recurrences, especially when age is over 30s and on head and neck region.

  • Purpose: We evaluated treatment outcomes of thymic carcinomas to determine prognostic factors for survival. Materials and Methods: Between May 1988 and May 2009, 41 patients had pathologic diagnosis of thymic carcinoma in Seoul National University Hospital, Seoul, Korea. Of these, 40 patients were followed up to 188 months after treatment. The mean age of all patients was 58.3 years and male to female ratio was 23 to 17. Results: Among 30 patients who underwent surgical resection, 26 achieved R0 resection and postoperative radiotherapy (PORT) was performed in 22 patients (73%). Various chemotherapeutic regimens were given with local treatment modalities, surgery and/or radiotherapy, in 12 patients. The 5-year locoregional control (LRC), distant metastasis-free survival, progression-free survival (PFS), and overall survival were 79.4%, 53.0%, 42.6%, and 63.6%, respectively. Patients with Masaoka stage I or II showed excellent prognosis of 5-year PFS around 90%. In advanced stages, invasion of the great vessels or atrium by thymic carcinomas was negative prognostic factor for PFS in univariate analysis. Lymph node involvement was statistically significant factor for LRC and PFS. Local or regional recurrence was infrequent after surgical resection followed by PORT, while distant metastasis was the major component of treatment failure. Conclusion: Complete resection followed by PORT provided remarkable local control without severe acute toxicities in patients with stage II and favorable stage III thymic carcinoma. Invasion of the great vessels or atrium was statistically significant prognostic factor for PFS.

  • Adenoid cystic carcinoma (ACC) in the lacrimal gland is a very rare disease with poor overall prognosis. Its primary treatment is surgical excision, including orbital exenteration and radical orbitectomy, which is combined with radiotherapy and chemotherapy. Age, histopathologic type, bone invasion, and tumor extent are known factors that affect the prognosis of ACC. Furthermore, perineural invasion is highly associated with local tumor recurrence and tumor base invasion. Here, we report a rare case of ACC in the lacrimal gland with superior sagittal sinus invasion that repeatedly recurred after the surgical excision.

  • A 14-year-old, 7.4 kg, neutered male mongrel dog presented with vomiting, anorexia, and hematuria starting 3 days prior to admission. Serum biochemical profiles indicated severe azotemia. Computed tomography revealed loss of normal left kidney structure. The organ was 1.5 to 2 times larger than the right kidney with mixed attenuation. Histopathologic examination was performed after nephrectomy. The renal mass and mesenteric membrane were positive for vimentin and stained blue with Masson's trichrome. In conclusion, this was a rare occurrence of primary renal fibrosarcoma, most likely originated from the renal capsule, with local invasion into the mesenteric membrane.

  • Pilomatrix carcinoma originates in the matrix cell and is marked by exophytic growing and common local recurrence. There is no established treatment for wide local invasion and metastasis of the pilomatrix besides wide surgical resection. We report a case of rapidly progressive pilomatrix carcinoma, which arose around an Eloesser open window with direct invasion to the adjacent tissue.
