Diffuse sclerosing papillary carcinoma(DSPC), a variant of papillary carcinoma of the thyroid, is characterized by diffuse involvement of one or both thyroid lobes, and histologic features such as prominent sclerosis, intense lymphocytic infiltrate, numerous psammoma bodies, and squamous metaplasia together with the characteristic cytoarchitectural pattern of classical papillary carcinoma. We experienced a case of fine needle aspiration cytologic(FNAC) findings of DSPC, which was confirmed by histologic examination of the thyroidectomy specimens. The patient was 26 years old female who presented with diffuse firm enlargement of the thyroid gland with enlargement of many cervical lymph nodes. FNAC smears showed numerous psammoma bodies, many lymphocytes, metaplastic squamous cells, absence of stringy colloid, and epithelial cells showing classical features of papillary carcinoma, such as nuclear grooves, intranuclear unclusions, and ground glass chromatin pattern.

There have been few reports on the survey of pathological findings of cetaceans stranded on the coast of Japan. This is partly because of lack of the procedures and/or network of systemic sampling of fresh tissues for the pathological study of stranded marine mammals. In contrast, there are a numbers of reports on the cause of illness and death in wild, free-living cetaceans examined in other countries; the commonest cause of death was parasitic and bacterial pneumonia except for entanglement in fishing gear. Anthracosis, lung and hilar lymph nodes polluted by suspended particulate matter in the air, has been recently found in some cetaceans stranded on the coast of Japan. In addition to the data from the chemical analysis of tissues, scientific data obtained from pathological study of stranded marine mammals would be also one of the useful base for the assessment of global environment. Usefulness of metallothionein in the hepatopancreas of crabs as a biomarker of marine pollution monitoring was also discussed in this study.

Background: The relation ofsurvivin gene expression to survival and surgical prognostic factors in the patients with endometrial carcinoma is unclear. Materials and Methods: In this study, 62 cases who were operated due to endometrial carcinoma were investigated between 2003 and 2011 in the the gynecological oncology clinic of Female Disease Training and Investigation Hospital of Etlik Zubeyde, Hanim, Turkey. Clinical and surgical prognostic factors were investigated by screening the records of these cases. With the standard streptavidin-biotin immune peroxidase method, cytoplasmic and nuclear expression of survivin was investigated in sections with specific antibodies (1:100, diagnostic Bio Systems, USA) primer. The aim was to elucidate any relation between survivin expression and defined prognostic factors and survival. Results: There was no statistically significant relationship between cytoplasmic and nuclear indexes identified for survivin and age, body mass index, the levels of preoperative hemoglobin, platelet and Ca 125, stage, grade, lymph node meastasis, the number of meta statical lymph nodes (total, paraaortic and pelvic), myometrial invasion, serosal invasion, adnexal involvement, the presence of acid in the first diagnosis, the involvement of omentum, the adjuvant treatment application of the cases, the presence of recurrence and rate of mortality (p>0.05). Statistical significance was noted for the presence of advanced stage lymph node metastasis (pelvic, paraaortic, pelvic and paraaortic), serosal involvement, positive cytology, lymph vascular space invasion, intra abdominal metastasis, and omentum involvement. When investigated the relation between cytoplasmic and nuclear survivin indexes and total survival, the result was not statistically significant (p>0.05). Conclusions: In our study, there was no statistically significant relationship between the rates of cytoplasmic and nuclear survivin expression with identified prognostic factors and total or non-disease survival.

Purpose: Pre-operative lymph node (LN) size is a valuable parameter for determining treatment strategy for gastric cancer. However, a correlation between LN size and metastasis has not been established. Materials and Methods: Thirty-six LN-positive (LNP) and matched 36 LN-negative (LNN) patients were included, and pathology slides of the LNs of these patients were reviewed. All the LNs were measured along the long-axis (LA) and short-axis (SA), manually. Results: Average retrieved LNs were $37.3{\pm}19.8$ and $40.5{\pm}11.6$ in the LNN and LNP groups, respectively. In total 2,800 LNs, including 136 metastatic LNs (MLNs) and 2,664 non-metastatic LNs (nMLNs), were evaluated. Mean length was significantly more in MLNs along both, the LA and SA (MLN_LA vs. nMLN_LA: $4.97{\pm}3.84$ vs. $3.37{\pm}2.40mm$, MLN_SA vs. nMLN_SA: $3.86{\pm}3.19$ vs. $2.43{\pm}1.59mm$; P<0.001). However, 92.6% (126/136) and 95.6% (130/136) of MLNs were <10 mm along the LA and SA, respectively. In addition, only 22.2% of the LNP group exhibited an MLN as the largest LN. Conclusions: Pre-operative multi-detector computed tomography has limited ability in estimating the presence of metastasis in LNs because most MLNs are less than 10 mm, and only a small proportion of the LNP group exhibits an MLN as the largest MLN.

A pathologic review was made of 1547 cases of thyroid nodule during the 20 years from 1970 to 1989 at the department of Head and Neck surgery of Presbyterian Medical Center in Chonju. 1547 cases were analysed in regard to cancer incidence of thyroid nodule, correlation of preoperative diagnosis with pathology and of frozen section diagnosis with final pathology, surgical procedures employed in managing thyroid itself, location of metastatic nodes, further definite procedure in cnacer cases, effectiveness of prophylactic neck dissection with lymph node pathology. The results are summarized as follows: 1) The cancer incidence of thyroid nodule was 21.7%. 2) The incidence of thyroid cnacer in total neoplasms increased from 1.6% to 2.9%. 3) The thyroid cancer was prevalent in female(5.9:1) and in fifth, fourth and sixth decade of life. 4) The incidence of solitary cold nodule in thyroid cancer was 72.7% (210/289). S) The incidence of thyroid cancer in solitary cold nodule was 28.7% (210/782). 6) The false negative of frozen section (1240 cases) was 19.8%. 7) Histologically, well differentiated carcinoma comprises about 94% of all cases and papillary carcinoma was 78.5% of all cases 8) The most frequent lymphatic metastasis was pre- & paratrachel nodes(63.3%), followed by Level III(50%) and Level II(47.7%). 9) 47.7% among 130 cases of papillary adenocarcinoma and 12.5% among 16 cases of follicular adenocarcinoma, each group treated with prophylactic neck dissection, were confirmed to be occult cervical node metastasis.

Background: Prognostic biomarkers in breast cancer are routinely investigated in the primary tumors to guide further management. However, it is proposed that the expression may change during the disease progression, and may result in a different immune profile in the metastatic nodes. This work aimed to investigate the expression of breast prognostic biomarkers in primary tumors and in its axillary nodal metastasis, to estimate the possible discordant expression. Materials and Methods: 60 paired primary and axillary nodal metastasis samples were collected from patients with primary breast cancer with positive nodal deposits, diagnosed at the Maadi Military Hospital, Cairo, Egypt, during the year 2013. ER, PR and HER2 expression was assessed by immunohistochemistry in all samples Results: 48.3% of the included cases showed concordant results for both ER and PR receptors between the primary tumor and its nodal metastasis while 51.7% showed discordant results and the discordance level was statistically significant. On the other hand, 70% of the cases showed concordant Her2 results between the primary tumors and the nodal deposits, 30% showed discordant results and the difference was significant. Conclusions: The study indicated that the discordance in ER and PR receptor expression between the primary breast tumor and their nodal metastasis may be significant. The possible switch in the biomarker status during the disease progression is worth noting and may change the patient therapeutic planning. So, whether the treatment selection should be based on biomarkers in the lymph node is a topic for further studies and future clinical trials.

Purpose: To evaluate the diagnostic accuracy of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography/computed tomography (PET/CT) in predicting pelvic lymph node (LN) metastases in patients with cervical cancer. Materials and Methods: From January 2009 to March 2015, 114 patients with FIGO stage IA1-IIB uterine cervical cancer who underwent hysterectomy with pelvic lymphadenectomy and took CT, MRI, and PET/CT before surgery were enrolled in this study. The criteria for LN metastases were a LN diameter ${\geq}1.0cm$ and/or the presence of central necrosis on CT, a LN diameter ${\geq}1.0cm$ on MRI, and a focally increased FDG uptake on PET/CT. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for pelvic LN metastases were estimated. Results: The sensitivity, specificity, PPV, NPV, and accuracy for detection of pelvic LN metastases were 51.4%, 85.9%, 41.3%, 90.1%, and 80.3% for CT; 24.3%, 96.3%, 56.3%, 86.8%, and 84.6% for MRI; and 48.6%, 89.5%, 47.4%, 90.0%, and 82.9% for PET/CT, respectively. The sensitivity of PET/CT and CT was higher than that of MRI (p=0.004 and p= 0.013, respectively). The specificity of MRI was higher than those of PET/CT and CT (p=0.002 and p=0.001, respectively). The difference of specificity between PET/CT and CT was not statistically significant (p=0.167). Conclusion: These results indicate that preoperative CT, MRI, and PET/CT showed low to moderate sensitivity and PPV, and moderate to high specificity, NPV, and accuracy. More efforts are necessary to improve sensitivity of imaging modalities in order to predict pelvic LN metastases.

Gastric metastasis from ovarian carcinoma is extremely rare and the prognosis for patients is poor. We report a case of multimodal treatment improving the survival time of a patient with gastric metastasis from ovarian cancer. A 73-year-old woman with known serous ovarian cancer was admitted to the hospital due to epigastric pain and dyspepsia. On esophagogastroduodenoscopy, a protruding mass was noted at the gastric antrum. She underwent distal gastrectomy with Billroth I anastomosis and lymph node dissection, including the para-aortic lymph nodes. The final pathology revealed gastric metastasis from ovarian serous adenocarcinoma. In this case, after cytoreductive surgery, chemotherapy was performed each time a recurrence was diagnosed, and remission was accomplished. She survived for 108 months after the first diagnosis of the metastatic tumor in the stomach. Multimodal treatment of metastatic lesions since the first diagnosis allowed the patient to survive longer than those in previous reports.

Castleman's disease (CD) is an uncommon benign lymphoproliferative disorder of unknown etiology. Histopathologically, it is divided into three types: hyaline-vascular, plasma cellular, and multicentric CD. The mass usually presents asymptomatically; however, it can cause non-specific symptoms such as fever and fatigue. Although CD can be found wherever lymph nodes are present, 75% of cases are reported in the mediastinum, and occurrence in the head and neck is rare. Herein, we report a rare case of CD presenting as a superficial mass in the temporal region. To the best of our knowledge, this is the first report of temporal CD in Korea involving a young patient.
