Hyperkeratosis of the renal pelvis and ureter is a rare condition and is explained by the metaplastic change from transitional to cornified squamous epithelium. This lesion is frequently associated with, and perhaps caused by chronic urinary infection, but potentially premalignant, accompaning with carcinoma in about 10 to 20 per cent of the cases at the time of diagnosis. A case of hyperkeratosis of renal pelvis & ureter which was clinically suspected of carcinoma in a 49-year old woman with a long history of chronic pyelonephritis is presented with review of literature.

Adenosquamous carcinoma of stomach is a mixed glandular-epidermoid tumor where both components are neoplastic. Its incidence is extremely rare. The five theories on the origin of squamous components are 1) island of ectopic squamous epithelium in the gastric mucosa, 2) squamous metaplasia of gastric epithelium, 3) squamous differentiation in a preexisting adenocarcinoma, 4) endothelial cell differentiated toward squamous elements, and 5) totipotential undifferentiated cells of the gastric mucosa. We experienced three cases of adenosquamous carcinoma. Case 1 was a 71-year-old female patient; an ulcerative lesion was present in the pylorus, measuring 5 cm in diameter. Case 2 was a 57-year-old male patient; an ulcerative lesion is present in the pylorus, measuring 6 cm in diameter. Case 3 was a 58-year-old female patient; an ulcerative lesion was present in the body and fundus, measuring 10 cm in diameter. Microscopic examination revealed a mixed malignant squamous and adenomatous component.

or =50 years), there was a significant association between oral cancer risk and high BMI in female subjects younger than 50 years of age (OR=3.92, 95% CI 1.03~14.9, P for trend=0.04), but not in older (> or =50 years) female subjects (OR=1.11, 95% CI 0.55~2.24, P for trend=0.76). There was no significant relationship between BMI and oral cancer risk in any of the male age subgroups.CONCLUSION: Our study provides the first epidemiological evidence supporting an association between obesity and an increased risk of oral cancer.]]>

Midtrimester genetic amniocentesis has been a gold standard for prenatal diagnosis in antenatal care since last 25 years. After the triple serum marker test was introduced as a prenatal screening method for Down syndrome, the frequency of genetic amniocentesis was increased. OBJECTIVE: To determine the complication, risk of amniocentesis and detection rate of chromosomal abnormality. MATERIAL AND METHODS: A retrospective clinical analysis of 1,064 midtrimester genetic amnicentesis in IL Sin Christian Hospital antenatal clinic from Jan 1995 to Dec 1997. Chi square test was used for the statistical analysis and p value < 0.05 was considered significant. RESULTS: Amnicentesis were significantly increased in the age of 35-39 yrs and 40yrs over. And also the incidence of chromosomal abnormality was higher than younger age group. The indications of amnicentesis were screen positive of triple marker test(43%), advanced maternal age(20.8%), abnormal beta-hCG level, past history of chromosome abnormality or malformed baby and abnormal alpha-FP level in order. Total number of chromosomal abnormalities was 30 and the incidence of chromosomal abnormalities was 2.8%(30/1,064). The complications were developed in 13 cases and fetal loss rate was 0.78%(9/1,064). CONCLUSION: The detection rate of chromosomal abnormality in midtrimester amnicentesis for prenatal diagnosis was high and relatively safe procedure but, we should be attention to more careful manipulation.

Because melanocytes are found throughout the leptomeninges, primary melanotic pigmented tumors such as pigmented meningioma, malignant melanoma, melanoblastosis, and melanocytoma can arise from this region. Melanocytomas have been described in the literature as isodense or hyperdense compared with brain parenchyme, as seen on noncontrast-enhanced CT, and as showing relatively homogeneous enhancement. MR imaging demonstrates a high signal on T1-weighted images, and an iso to hypointense signal on T2- weighted images. We report the imaging findings of a melanocytoma that showed hyperdense attenuation on precontrast CT with homogeneous enhancement and hyperintense signal intensity on T1-weighted images and dark signal intensity enhancement on T2-weighted images, and also review the literature.

Splenic abscess is uncommon, but often fatal entity characterized by high mortality rate which ranges from 60 to 100%, due to nonspecific clinical presentation and failure to preoperative definitive diagnosis. Clinical symptom or simple X-ray was not helpful in diagnosing splenic abscess. Perhaps the most useful information was obtained from the scanning and computerized tomography. Emphasis is placed on the necessity for prompt diagnosis and surgical intervention when splenic abscess was suspected. We have experienced three cases of splenic abscess. Case 1 was a 59 year-old male patient; the cause was possibly direct spreading from pancreatitis; The culture demonstrated klebsiella oxytoca. Case 2 was a 42 year-old female patient; the abscess was produced by preceding infarct. Case 3 was a 64 year-old female; metastatic adenocarcinoma was identified in the soft tissue around spleen, that suggest causative factor. All three cases showed multiple abscesses.
