RESUMEN

BACKGROUND AND OBJECTIVES: Diversity of opinion regarding the impact of fine needle aspiration biopsy (FNAB) on clinical decision-making has persisted, mostly because of its high false-negative rate and lower sensitivity in salivary gland diseases when compared to other head and neck tumors. The objectives of this study are to evaluate the utility of FNAB in the diagnosis of salivary gland pathologies and to assess its capacity to provide an accurate medical and surgical treatment. MATERIALS AND METHODS: From June 1989 through January 2000, FNABs were carried out on 50 patients with salivary gland diseases. Among them, 34 patients were confirmed histologically after surgery and others clinically. RESULTS: Regarding the capacity of FNAB to discriminate between neoplastic (malignant and benign) and non-neoplastic lesions, FNAB correctly diagnosed 87% (41/47) of lesions. The values for sensitivity, specificity and accuracy of differentiation for neoplastic lesions were 17%, 95% and 87%, respectively. FNAB's diagnostic accuracy, sensitivity and specificity to Warthin's tumor was higher than to those of pleomorphic adenoma. CONCLUSION: Fine needle aspiration biopsy of salivary gland diseases is a helpful adjunctive test for diagnosis and treatment planning.

RESUMEN

OBJECTIVES: To investigate the relationship between the Helicobacter pylori (H. pylori) colonization and the grade of gastritis in the antrum and in the body of patients with duodenal ulcer (DU) or benign gastric ulcer (BGU). METHODS: This study was performed in H. pylori-positive 220 DU patients and 180 BGU patients. H. pylori density was evaluated by modified Giemsa staining and CLO test, and gastritis grade was graded by H+ACY-E staining in the antrum and in the body. RESULTS: H. pylori grade by Giemsa staining was 1.24 in the antrum and 0.82 in the body for DU group (p +ADw- 0.01), and those of BGU group were slightly reversed, 0.83 and 0.87, respectively, but without statistical significance. Similarly H. pylori grade by CLO test was 3.1 in the antrum and 2.8 in the body for DU group (p +ADw- 0.01), and those of BGU group 2.3 and 2.6 (p +ADw- 0.05), respectively. In contrast, gastritis grade was 1.7 in the antrum and 1.2 in the body for DU group (p +ADw- 0.01), and those of BGU group 1.6 and 1.3 (p +ADw- 0.01), respectively, similar to those of DU. However, there was a correlation between H. pylori grade and gastritis grade in the antrum and in the body, not only in DU but also in BGU group (p +ADw- 0.01). CONCLUSION: In spite of different distribution patterns of H. pylori between DU group and BGU group, gastritis grade of the antrum was significantly higher than that of the body in both DU and BGU. However, gastritis is correlated with H. pylori density not only in DU but also in BGU patients. It looks like the inflammatory reaction to H. pylori is stronger in the antrum than in the body.

RESUMEN

Granular Cell Tumors(GCT) were originally described as myoblastic myomas. Subsequent scientific investigations elucidated the origin of this tumor as Schwann cells . Usually they have a predilection for head and neck, but also can occur in many other organs. This tumor is believed to originate from Schwann cells based on subsequent scientific investigations. Although it usually appears in the head and neck, it can also appear in other organs, as well. Endobronchial granular cell tumors are rather rare and should be differentiated from other common diseases of endobronchial location endobronchial diseases such as bronchogenic carcinoma and endobronchial tuberculosis, especially in Korea . We report a A case of a patient with an extremely rare condition of endobronchial granular cell tumor concurrent with malignant mediastinal tumor in a patient (delete) is reported.

RESUMEN

The appendiceal mucocele is a rare disorder, usually found incidentally during ultrasonography or radiologic studies. Mucoceles of the appendix include benign or malignant disease. Both of benign cystadenoma and malignant cystadenocarcinoma are characterized by an obstructed, mucin-filled appendix displacing the cecum. We experienced a case of partial obstruction of large bowel who had a cystadenoma at appendix and a colon cancer at other site on operation field. Here in, we report a case of appendiceal mucocele and concominant colon cancer with the review of literatures.

RESUMEN

The appearance of a tumor in the chest wall is rare compared to that in any other part of the body. It can be classified into benign and malignant types and can be located in the rib, clavicle, sternum, cartilage and soft tissues. Tumors that are metastatic are commonly located in the lung, breast, bone and pleura. But, the soft tissue mass of anterior chest wall is rarely metastasized from a distant organ that is not confined to the thoracic cavity. This and thus has rarely been described. A 68-year-old man was admitted to our hospital with a chief complaint of resting dyspnea. A huge non-tender mass of about 10*15 cm in size was visible on his left lower anterior chest wall. We pathologically confirmed that the mass was a metastatic renal cell carcinoma of clear cell type by incision biopsy. Through an incision biopsy, the mass was pathologically confirmed as a metastatic renal cell carcinoma of the clear cell type.

RESUMEN

Mucormycosis is an infection caused by fungi of the class Zygomycetes, order Mucorales. These are usual ubiquitous saprophytes but occasionally cause opportunistic infection in immunocompromised patients. Typically, these fungi invade blood vessels, and produce thrombosis and tissue infarction, so causing host fatality. These infections can be categorized into rhinocerebral, pulmonary, widely disseminated, gastrointestinal, cutaneous and miscellaneous form. Most of mucormycosis cases reported in Korea were rhinocerebral form except for three cases, which were gastrointestinal mucormycosis, accompanied with hematologic malignancy or immunosuppressing treatment. We experienced a 58-year-old male with gastric mucormycosis, who had diabetes and mild uremia without hematologic malignancy and immunosuppressive treatments. His chief complaints were abdominal pain and melena, and gastroscopy showed a 3 3 cm irregular edged ulcer considering malignancy. Its histological findings showed large, thin-walled, non-septate and right-angled branching fungal hyphae in necrotic tissue, diagnosed as mucormycosis. Finally he was dead due to severe hematemesis.

RESUMEN

PURPOSE: In gastric cancer, metastasis to the paraaortic lymph nodes had been regarded as an incurable factor, but many cases of long term survival have been reported with dissection of metastatic paraaortic nodes. And several reports suggested survival benefit with paraaortic lymph node dissection (D4) in advanced gastric cancer. In patients with advanced gastric cancer who underwent paraaortic lymph node dissection we tried to evaluate the factors predisposing metastasis in these nodes and survival data. MATERIALS AND METHODS: The authors analyzed retrospectively pathological features of 95 patients who underwent paraaortic lymph node dissection for advanced gastric cancer at Kangnam General Hospital Public Corporation from May 1991 to Feb. 1998. And we also analysed survival results of 72 cases among them. We excluded 18 cases of distant metastasis (3 liver metastasis, 15 peritoneal seeding), 2 operative mortalities, 1 other disease mortality, and 2 unknown causes of death in survival analysis. RESULTS: The frequencies of paraaortic lymph node metastasis were 0.0% (0 of 32 cases) in T2, 19.2% (10 of 52 cases) in T3, 18.2% (2 of 11 cases) in T4. And those of paraaortic lymph node metastasis were 5.8% (3 of 52 cases) in antrum, 14.3% (3 fo 21 cases) in body, 20.0% (3 of 15 cases) in cardia, and 42.9% (3 of 7 cases) in whole area. The five-year survival rates (5 YSR's) in relation to the paraaortic lymph node (No16) status was 0.0% in No16 , and 57.8% in No16 with D4 of advanced gastric cancer. The 5 YSR's were 78.1%, 40.8% and 0% in T2, T3 and T4, respectively and 93.8%, 64.2%, 24.2% and 0.0% in n0, n1, n2 and n3, respectively and 88.9%, 80.5%, 57.9% and 0.0% (47.6%) and 0.0% in stage IB, II, IIIA, IIIB and IV, respectively. CONCLUSION: The depth of gastric wall invasion and the location of primary tumor were significant predisposing factors to para-aortic lymph node metastasis in multivariate analysis (p<0.05). Survival of No16 metastasis was very poor. And three factors of T stage, n stage, and Borrmann type were also prognostically significant in terms of five year survival in cases of D4 of advanced gastric cancer in multivariate analysis (p<0.05).

RESUMEN

The assessment of epithelial changes in gastric mucosal biopsies has been one of the major problems caused by inconsistencies in and disagreements about nomenclature and interpretation. To resolve these issues, members of the Study Group for Pathology of Digestive Diseases reviewed microslides of 50 gastric lesions showing varying degrees of mucosal abnormality and reached the following consensus; 1) the proliferating gastric epithelium can be divided into hyperplastic and neoplastic; 2) the term "dysplasia" is reserved for the microscopic epithelial changes that are unequivocally neoplastic; 3) Biopsy specimens can be categorized as regenerative(negative for dysplasia), indefinite(questionable dysplasia), positive(positive for dysplasia) and overt carcinoma; 4) The positive category can be divided into two subgroups, high grade dysplasia and low grade dysplasia. Criteria for each grade are presented and discussed. We offer these guidelines for establishing the correct diagnosis of the gastric mucosal biopsy specimens and for prospective studies.

RESUMEN

The hyaline membrane disease is not a common disease in Korea. Only a few reports of small scale are avaiable in the literature. We have experienced 5 cases of HMD during approximately 1 year period. The diagnosis was made either on characteristic clinical and roentgenological features or postmortem examination. The birth weights of these cases were in the range of 1,000-1,500gm in 2 cases and 2,000-2,500gm in 3 cases. And their gestational age was 28-34 weeks in most of the cases. Three cases were delivered by C-section. There was 1 case of placenta previa. Four of these 5 cases died after average 18 hours postnatum. Postmortem findings in two cases were characterized by typical hyaline membrane lining th respiratory bronchioles and alveolar ducts. Other prominent findings were atelectasis, interstitial edema and congestion and lymphatic dilatation. One case complicated with multifocal bronchopneumonia and perinatal telencephalic leukoencephalopathy. The other case showed acute subarachnoid hemorrhage probably from germinal matrix hemorrhage.
