Calcification of gastric carcinoma is unusual and most of the reported cases were of the mucinous type. This report describes two cases of papillo-tubular adenocarcinoma of the stomach with psammomatous calcification confined only to the papillary portion. Calcification was so heavy that specimen X-ray was able to clearly delineate its distribution. Microscopically, the calcification was confined to the papillary carcinoma area and was not found in the area of the tubular adenocarcinoma. Polymorphic calcific bodies were found in the supportive stroma of papillae and extrapapillary spaces as concentrically laminated psammoma bodies. They were also found in tumor cells as minute corpuscles. The mechanism of neoplastic mineralization in these cases seemed different from ontogenic calcification of mucinous gastric carcinoma and we postulated the mechanism of psammomatous calcification which is referred as intracellular calcification.

OBJECTIVETo evaluate the prognostic significance of micropapillary pattern (MPP) in adenocarcinoma of lung.
METHODSNinety-one consecutively excised cases of pulmonary adenocarcinoma, including follow-up data, were retrospectively studied. These tumors were divided into 2 major groups: those with MPP and those without MPP. The former was further subdivided according to extent of the micropapillary component, as follows: MPP + (constituting 1% to 10% of the tumor), MPP ++ (constituting 11% to 30% of the tumor) and MPP +++ (constituting more than 30% of the tumor).
RESULTSThe overall 5-year survival rate was 64.8%. The 5-year survival rates were 88.9% for stage I tumors, 46.2% for stage II tumors, and 23.8% for stage III tumor respectively (P = 0.000). The extent of micropapillary component showed no correlation with tumor stage, size and 5-year survival rate (P = 0.065, 0.358 and 0.206, respectively). On the other hand, the 5-year survival rate was 41.5% for patients in the MPP-positive group (number = 41) and 84.0% for patients in the MPP-negative group (number = 50). The percentage of nodal metastasis in MPP-positive group was also higher than that in MPP-negative group (P = 0.000). In pulmonary adenocarcinoma, this characteristic histology correlated with tumor stage and size, but not with patient's gender and smoking history. Within the same stage, the 5-year survival rates of MPP-positive and MPP-negative groups were as follows: for stage I, 78.6% versus 92.6% (P = 0.1548), for stage II, 30.0% versus 100% (P = 0.0598), and for stage III, 17.7% versus 28.6% (P = 0.4045).
CONCLUSIONSMPP in primary pulmonary adenocarcinoma, even when only constituting a minor component, predicts an aggressive clinical behavior and is associated with poor prognosis. Although it may not be an independent prognostic factor, presence of this histologic pattern should alert clinicians for more active treatment and closer follow up.

Compared with other types of cancers, pancreatic cancer is one of the most dreadful malignancies and is fifth leading cause of cancer-related death in Korea. It is difficult to expect early diagnosis or improvement in prognosis due to lack of specific early symptoms and effective diagnostic methods. Whereas cystic neoplasm of the pancreas is a rare type of pancreatic tumor, surgical resection provides good prognosis because of its low possibility of local invasion or distant metastasis. In case of pancreatic cystic tumor, radiologic differentiation between benign and malignant lesions is crucial for the selection of appropriate treatment and the prediction of prognosis. And ductal adenocarcinoma of pancreas presenting in cystic form is an uncommon type of cystic tumor, making it extremely rare among all pancreatic malignancies. We report two cases of atypical pancreatic ductal adenocarcinoma presenting as solid pseudopapillary tumor and intraductal papillary mucinous neoplasm, respectively.

7.Analysis of lymph node metastasis factors in papillary thyroid microcarcinoma.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2007;21(15):679-682
OBJECTIVE:
To analyze the factors of lymph node metastasis in papillary thyroid microcarcinoma and to evaluate the significance of the selective neck dissection.
METHOD:
Records of 82 patients with papillary thyroid microcarcinoma were retrospectively analyzed. Sixty patients were received a selective neck dissection (Group 1), while twenty-two were not (Group 2).
RESULT:
In Group 1, 13 patients were found metastasis. The incidence of metastasis was 21. 67% (13/60). The frequency of nodal metastasis with a carcinoma < 0.7 cm was 4.76%, while > or = 0.7 cm was 30.77% (P < 0.05). All patients were followed-up from 9 to 14 years (mean 59.8 months). No patients relapsed or died, and no one was found distant metastasis.
CONCLUSION
The papillary thyroid microcarcinoma had a high tendency to metastasize. It is more significant to perform selective neck dissection in tumors > or = 0.7 cm.

OBJECTIVE:
To investigate the value of sentinel lymph node of papillary thyroid carcinoma exploring and measuring in the metastasis of the cervical lymph node of thyroid carcinoma.
METHOD:
The sentinel lymph node were investigated by injecting the methylene blue around 25 cases of thyroid tumors. The lymph nodes dyed in blue and obtained from selective lymph node dissection were examined by pathology, respectively. The value of the sentinel lymph nod were evaluated.
RESULT:
The sentinel lymph nodes dyed in blue were identified in 22 cases which account for 88.0% of all the 25 cases. Nineteen cases of the sentinel lymph node were positive by pathology, of whom 13 cases were verified positive in other area. Six cases were negative.
CONCLUSION
It is of great value that sentinel lymph node of thyroid carcinoma can indicate the metastasis of the cervical lymph node of thyroid carcinoma.

OBJECTIVETo explore a cosmetic incision in the neck dissection for differentiated thyroid carcinoma.
METHODSAn extended collar incision was used for neck dissection in 82 consecutive patients with thyroid carcinoma from May 1999 to December 2006. The incision was designed to start as a conventional thyroid collar incision, and then to extend it along the skin crease to the anterior border of trapezium, so to avoid the vertical limb of conventional hockey stick incision. There were 60 females and 22 males in this series, with a median age of 40.5 years (range, 10 to 80 years). Ninety-six procedures of neck dissection were performed in 82 patients, including one radical neck dissection, one type I modified neck dissection, 8 type II modified neck dissections, and 86 type III modified neck dissections.
RESULTSThe average time of anesthesia was 197 minutes. The average dissected lymph nodes were 37.5, with average metastasis in 8.8 nodes. Eight patients (9.8%) developed complications related to neck dissection. The follow-up period in these patients were 1 to 96 months with a median follow-up time of 23 months. Cervical recurrence was found in only one patient (1.2%). Neither death nor distant metastasis was observed in this series.
CONCLUSIONIt is feasible to perform a modified neck dissection for differentiated thyroid cancer through the extended collar incision. The preliminary results show that the above described incision is not only oncologically safe, but also offers a cosmetic benefit for the patient with thyroid carcinoma.

OBJECTIVETo study the surgical management of metastatic disease in the conjunctive area between the neck and thorax and its efficacy.
METHODSFourteen cases with metastatic node disease in the area between neck and thorax were collected and analysed. Eleven tumors were from the thyroid cancer, and the other three were from the hypopharyngeal cancer, esophagual cancer and malignant pheochromocytoma, respectively. The clavicle was displaced or resected, and the upper half of the manubrium might also be resected when necessary. The recurrent laryngeal nerve and phrenic nerve were exposed and protected. The metastatic disease was completely removed with the internal jugular and/or the brachiocephalic vein resected or spared, depending on the disease condition.
RESULTSIn 10 cases with metastases from the thyroid, no local recurrence was found within the follow-up period from 2 to 5 years. In contrast, no patient with metastatic disease from hypopharyngeal or esophageal cancer survived more than 11 months. No serious complications were found in this group.
CONCLUSIONSThe surgical treatment of node metastases in the conjunctive area between neck and thorax from the well-developed thyroid cancer has promising effect and is comparatively safe.
