Adenocarcinomas (AC) are the most frequently encountered carcinomas. It may be quite challenging to detect the primary origin when those carcinomas metastasize and the first finding is a metastatic tumor. This study evaluated the role of sex hormone binding globulin (SHBG) positivity in tumor cells in the subclassification and detection of the original organ of adenocarcinomas. Between 1994 and 2008, 64 sections of normal tissue belonging to ten organs, and 116 cases diagnosed as adenoid cystic carcinoma and mucoepidermoid carcinoma of the salivary gland, lung adenocarcinoma, invasive ductal carcinoma of the breast, adenocarcinoma of stomach, colon, gallbladder, pancreas and prostate, endometrial adenocarcinoma and serous adenocarcinoma and mucinous adenocarcinoma of the ovary, were sent to the laboratory at the Department of Pathology at the Yuzuncu Yil University School of Medicine, where they were stained immunohistochemically, using antibodies against SHBG. The SHBG immunoreactivity in both the tumor cells and normal cells, together with the type, diffuseness and intensity of the staining were then evaluated. In the differential diagnosis of the adenocarcinomas of the organs, including the glandular structures, impressively valuable results are encountered in the tumor cells, whether the SHBG immunopositivity is evaluated alone or together with other IHC markers. Further extensive research with a larger number of cases, including instances of cholangiocarcinoma and cervix uteri AC [which we could not include in the study for technical reasons] should be performed, in order to appropriately evaluate the role of SHBG in the differential diagnosis of AC.

Eleven patients with esophageal diverticulum were operated on between August 1982 and August 1992 at the Department of Thoracic and Cardiovascular Surgery of Chonnam National University Hospital have been studied. 9 patients were male and 2 were famale and the age distribution was between 20 and 55 years. Various subjective symptoms were noticed preoperatively. Diagnosis was confirmed by esophagography. The types of esophageal diverticulum were traction type in 6 cases and pulsion type in 5 cases. There were nine cases of midesophageal diverticula, 1 cases of upper-thoracic esophageal diverticulum and 1 cases of epiphrenic diverticulum. Diverticulectomy alone in 10 cases and diverticulopexy was performed in 1 case. Fistulectomy in 5 cases, lobectomy in 1 case, segmentectomy in 1 case, and Eloesser`s procedure in 1 case were performed with associated procedures. There were no death or morbidity and all patients have achieved marked improvement of symptoms except three patients who had a concomitant mucoepidermoid tumor, had a complicated postoperative pyothorax, and had a postoperative recurrence of midesophageal diverticulum. Recurrence of symptoms were not noticed during follow up except 1 recurrence of diverticulum confirmed by esophagogram.

Epithelial-myoepithelial carcinoma(EMC) is a rare low grade malignant salivary gland neoplasm that most commonly occurs in the parotid gland but can also arise in minor salivary glands. It is a distinct neoplasm characterized by tubular and solid growth patterns and a dual cell population including an inner larger of cuboidal to columnar epithelial cells which are peripherally bounded by a layer of myoepithelial cells with distinctly clear cytoplasm. The clinical course is characterized by a high incidence of local recurrence and not infrequent distant metastasis. The differential diagnosis included acinic cell tumor, adenoid cystic carcinoma, mucoepidermoid carcinoma, sebaceous carcinoma and pleomorphic adenoma. We report a case of EMC of left parotid gland in a 55-year-old woman.

Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor which compromises about 6$\sim$8% of all tumors followed by the adenoid cystic carcinoma (ACC) and adenocarcinoma. Most deaths from salivary carcinomas are caused by recurrent or metastatic lesions that are resistant to conventional therapy. Therefore, knowledge of cellular properties and tumor-host interactions that influence the vascular metastasis is important for the design of more effective therapy of salivary carcinomas. Neoangiogenesis is essential for tumor growth, which is postulated to be fundamentally dependent on the induction of stromal neovascularization. However, how neovascularization takes place in live tissue has not been fully established, especially in recruitment and differentiation of endothelial cells in the salivary gland tumors. Vascular endothelial growth factor (VEGF) is a heparin-binding, dimeric polypeptide growth factor known to exert its mitogenic activity specifically on endothelial cells. VEGF has been shown th be directly involved in angiogenesis, which in essential for the pathogenesis of many solid tumors. von Willebrand factor (vWF) is a large multimeric protein synthesized by megakaryocytes and endothelial cells that enable platelets to adhere to exposed subendothelium and, as well, to respond to changes in the blood flow. Recent studies suggest that increased levels of vWF correlate with progression of disease, metastasis, or survival time and thus may have a prognostic significance. vWF is explained as an acute phase proteins which is increased in cancer or as a result of increased endothelial cell synthesis associated with tumor-induced angiogenesis. Due to adhesive properties of vWF, its increased concentrations may also contribute metastasis of tumor. In this study, we determined the mRNA expression of VEGF and vWF in salivary ACC, MEC and pleomorphic adenoma by in situ hybridization. As a result, stronger expression of VEGF and vWF was seen in salivary ACC and MEC which has more invasive nature than the salivary benign tumor.

Objectives: The best treatment for the malignant parotid tumor still remains to be defined, and a better knowledge about the tumor features that predict the treatment result is needed. The aim of this study is to evaluate the treatment outcomes and to suggest the optimal treatment modality for the parotid cancer. Materials and Methods: The clinicopathologic characteristics of 113 patients who were treated for parotid cancer from January 1990 to December 2002 were retrospectively analysed. Univalate analyses were performed to establish the prognostic influence of pateint age, gender, tumor size, histologic grade and lymph node metastasis. Results: The mean age was 46.4 years old (15-81 years) and. The male to female ratio was 1 : 1.1. The chief complaint was a palpable mass in 85%, pain was in 12.4% and facial nerve palsy was accompanied with 2.7%. The mean tumor size was 3.5cm in diameter. The most common malignant tumor was mucoepidermoid carcinoma (33.6%), followed by acinic cell carcinoma (15%), adenoid cystic carcinoma (11%), carcinoma expleomorhpic adenoma (11%), basal cell carcinoma (7%). The most common operative procedure was total parotidectomy (47.8%) and various types of cervical lymph node dissection were added in 69.9%. Postoperative radiotherapy was done in 61.1 %. Postoperative complications developed in 54 cases (47.8%), including 46 cases (40.7%) of facial nerve palsy and 9 cases (8%) of Frey's syndrome. Recurrences developed in 21 cases (18.6%) and deaths in 15 (13.3%). Cumulative survival at 5 year was 75.4%. Univariate analysis of clinical factors showed that histologic grade and positive cervical lymph node significantly influenced survival (p<0.05). Conclusion: These results suggests that the radical resection with lymph node dissection and postopertaive XRT would be necessary to improve the survival of the patients with high grade cancer or positive lymphnode metastasis.

The authors reviewed 106 cases of parotid gland tumor at Presbyterian Medical Center seen during the past 10 years between January, 1986 and December, 1995. The results were obtained as follows; 1) 86 cases(81.1%) were benign tumors and 20 cases(18.9%) were malignant tumors. 2) Overall male and female sex ratio was 1 : 1.4. 3) For benign tumors, the mean age was 47.9 and for malignant tumors, the mean age was 43.4. 4) Clinical manifestations in benign tumors were palpable mass in 86 cases(100%), pain in 6 cases(6.9%), facial nerve palsy in 2 cases(2.3%), lymphadenopathy in 1 case(1.2%); and in malignant tumors, palpable mass in 20 cases(100%), pain in 7 cases(35%), facial nerve palsy in 2 cases(10%) and lymphadenopathy in 3 cases(15%). Thus, the presence of pain, facial nerve palsy and lymphadenopathy suggest malignant tumors. 5) Operative procedures in benign tumors included superficial parotidectomy in 53 cases(61.6%), total parotidectomy in 10 cases(11.6%), local excision in 23 cases(26.7%); and in malignant tumors, superficial parotidectomy in 3 cases, total parotidectomy in 1 case, local excision in 1 case, superficial parotidectomy with supraomohyoid neck dissection in 6 cases, total parotidectomy with supraomohyoid neck dissection in 8 cases, total parotidectomy with radical neck dissection in 1 case. 6) Postoperative complications in benign tumors were transient facial nerve palsy in 14 cases, Frey's syndrome in 2 cases. In malignant tumors complications included transient facial nerve palsy in 3 cases and permanent facial nerve palsy in 1 case. 7) Pleomorphic adenoma was the most common benign parotid tumor and mucoepidermoid carcinoma was the most common malignant tumor. 8) In our review of 20 patients with malignant parotid tumors, all patients who received supraomohyoid neck dissection and postoperative radiation therapy remain alive from 1986 to 1995 years. Two deaths in this series were adenoid cystic carcinoma patients who failed to receive postoperative radiation therapy. These series of cases have been studied in order to determine whether supraomohyoid neck dissection and postoperative radiation therapy may have further therapeutic effect.
