1.Enteric Cyst in the Tongue.
Korean Journal of Pathology 1997;31(11):1237-1239
A case of enteric cyst in the anterior two-thirds of the tongue is reported. The patient, a 42 day-old female infant, presented with a protruding tongue mass since birth. Under the impression of ectopic thyroid gland or leiomyoma, complete resection was performed. The mass proved to be an enteric cyst, lined by small intestinal mucosa with an underlying coat of smooth muscle. Enteric cysts arising in the tongue is rare and only 8 such cases have been reported in the literature.

Angiogenesis depends on the net balance between positive and negative angiogenic factors. Tumor cells are angiogenic resulting from increased production of positive factors and decreased production of negative factors. Among these, vascular endothelial growth factor and glioma- derived angiogenesis inhibiting factor are related to glioblastoma multiforme. The p53 gene is more frequently mutated than any other known oncogene or tumor suppressor gene in human tumors including glioblastoma multiforme. Angiogenesis is reported to be controlled by p53 regulation in recent studies. To examine the effect of p53 overexpression on angiogenesis in glioblastoma multiforme, we performed immunohistochemical staining in 51 cases of glioblastoma multiforme, using monoclonal antibodies to p53 protein and factor VIII. 20 cases of low grade astrocytoma were used as control. p53 overexpression was present in 15(75%) of 20 cases of low grade astrocytoma and the mean vessel count was 37.7+/-9.9 at x200 field and 17.5+/-5.8 at x400 field. p53 overexpression was present in 35(68%) of 51 cases of glioblastoma multiforme and the mean vessel count was 91.9 45.8 at x200 field and 40.7 19.1 at x400 field. Mean vessel count in low grade astrocytoma with p53 overexpression was 39.4 10.2 at x200 field and 18.9 5.7 at x400 field, while in cases without p53 overexpression it was 32.4+/-7.6 at x200 field and 13.2 3.5 at x400 field. Mean vessel count in glioblastoma multiforme with p53 overexpression was 94.5+/-51.8 at x200 field and 42.1+/-16.8 at x400 field, while in cases without p53 overexpression it was 86.1+/-29.5 at x200 field and 37.1+/-16.8 at x400 field. The mean survival time was 12.4 months in the 39 cases of glioblastoma multiforme in which follow-up studies were possible. Significant prognostic factors were age, p53 overexpression and adjuvant therapy. These results show that p53 gene mutation is one of the many contributing factors to angiogenesis in glioblastoma multiforme. In addition, other oncogenes and tumor suppressor genes, as well as growth factors may be involved. Age, p53 overexpression and adjuvant therapy proved to be significant prognostic factors, while microvessel density was not.

Unstable microsatellite repeat sequences or DNA replication errors(RER) due to defective mismatch repair genes have been reported in a subset of sporadic colorectal tumors and in most tumors of patients of hereditary nonpolyposis colorectal carcinoma(HNPCC). To elucidate the clinicopathological correlation of these RER-positive cancers, we examined 16 cases of colorectal carcinoma of different histologic subtypes(6 cases of carcinoma with no gland formation, 5 cases of mucinous carcinoma and 5 cases of gland forming carcinoma). We detected RER in five cases. The patients with RER-positive cancers had a marked preponderance of carcinoma with no gland formations out of 6 carcinomas with no gland formation were RER-positive cancers) and of cancers proximal to splenic flexure(all of the RER-positive cases were proximal colon carcinomas). We conclude that RER-positive cancers have wiique pathologic features that may be useful for the screening and counselling of patients with hereditary colon cancers.

Two strains of vancomycin-resistant Leuconostoc species were isolated from blood cultures in two compromised patients. The isolates produced gas from Lactobacillus MRS booth, hydrolysed esculin, and produced no ammonia from arginine, thus fulfilling the major criteria as Leucorostoc spp. We recommend that clinical laboratories should perform susceptibility test to vancomycin for clinical isolates (especially from cerebrospinal fluid and blood) which resemble streptococci so as not to confuse Leuconostoc spp. with more commonly isolated pathogens such as streptococci.

Barrett's esophagus is a metaplastic process in which the squamous epithelium of the lowet esophagus is replaced by columnar epithelium. Most cases are believed to be related to prolonged gastroesophageal reflux. Detection of Barretts esophagus is important in that it results in adenocarcinoma in about 10% of patients. We report a case of adenocarcinoma arising from Barrett's esophagus in a 56 year-old man, diagnosed incidentally at a physical check-up. Grossly, the esophagogastric junction was irregular and there were two small ulcers in the lower esophagus. Microscopically, ihe squamous epithelium of the lower hagus was replaced by specialized intesinal mucosa with a small focus of adenocarcinona confined to the submucosa in one area. Many separate dysplastic foci were also present in the nearby esophageal mucosa.

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

Carcinosarcomas of the female genital tract have generally been regarded as a type of sarcoma. Recent studies, however, suggest the tumor may be more closely related to carcinoma and may represent metaplastic carcinoma in histogenesis. We analyzed clinicopathologic and immunohistochemical features of 10 carcinosarcomas to evaluate the relative importance of the carcinomatous and sarcomatous components in metastasis and recurrence. The primary tumor originated in the uterine body in seven cases, the uterine cervix in two and the ovary in one. Patient,s ages ranged from 54 to 71 years (mean, 64). The most common symptom of the uterine mass was vaginal bleeding. The median survival time was 21 months following diagnosis in five cases. Surgico-pathologic FIGO stages of five patients who received an operation were stage III and IV, but clinical FIGO stage of three patients (60%) among them were I. Lymphovascular invasions were identified in seven areas; five vascular invasion lesions showed the carcinomatous component alone, one the sarcomatous component alone, and remained one admixture of both components. Metastatic and recurrent lesions to the paraaortic lymph node, ovary, pelvic wall, or vaginal vault showed characteristically carcinomatous component only. Immunohistochemically, positive reactions for cytokeratin and epithelial membrane antigen were noted in the sarcomatous component of five cases. Vimentin positivity was detected in carcinomatous component of three cases. We conclude that the dominant element in carcinosarcomas of the female genital tract is the carcinomatous component. The survival rate of carcinosarcoma is extremely poor. The surgico-pathologic stage is better indicator of survival than the clinical stage. Immunohistochemical findings suggest that carcinosarcoma may represent a metaplastic carcinoma in histogenesis.

The clinicopathologic features and the comparative analysis of diagnostic methods in 42 patients having intestinal tuberculosis were studied. In all the cases, clinical and colonoscopic diagnosis was confirmed by histological examination. Abdominal pain was the most common symptom (54%). Twenty nine patients had active pulmonary tuberculosis which was confirmed by a chest X-ray, or an AFB smear and a culture of sputum. A transverse ulcer with surrounding hypertrophic mucosa and multiple erosion was the usual colonoscopic findings. The granulomas were usually located in the just upper and lower portion of muscularis mucosa. The direct smear and culture of the fresh biopsy material showed AFB in 11 (32.4%) and 12 cases (36.4%) respectively. Ziehl-Neelsen staining in serially sectioned slides from formalin-fixed, paraffin- embedded tissue revealed AFB in 15 cases (35.7%). An immunohistochemical stain for Mycobacterium bovis was done in all cases and 13 cases were positive (31%). A polymerase chain reaction (PCR) was done and showed positivity in 4 out of 20 cases of fresh biospy material and 12 out of 40 cases in paraffin embedded tissue. For the conclusive diagnosis of intestinal tuberculosis, a Ziehl-Neelsen stain is the most sensitive, fast, and cost-effective method. The diagnostic accuracy will be increased when other diagnostic methods such as tissue culture and PCR are coupled with this simple staining method.

We present a case of pulmonary artery catheter (PAC) placement through the right internal jugular vein, bridging vein and coronary sinus in a patient with previously unrecognized persistent left superior vena cava (LSVC) and diminutive right superior vena cava. A 61-year-old male patient was scheduled for mitral valve repair for regurgitation. Preoperative transthoracic echocardiography revealed dilated coronary sinus, but no further evaluations were performed. During advancement of the PAC, right ventricular and pulmonary arterial pressure tracing was observed at 50 and 60 cm, respectively. Transesophageal echocardiography ruled out intracardiac knotting and revealed the presence of the PAC in the LSVC, entering the right ventricle from the coronary sinus. Diminutive right superior vena cava was observed after sternotomy. The PAC was left in place for 2 days postoperatively without any complications. This case emphasizes that the possibility of LSVC and associated anomalies should always be ruled out in patients with dilated coronary sinus.
