A 62-year-old man with a complaint of back pain lasting 2 months was admitted. He also presented a huge abdominal tumor. Diagnostic imaging showed metastatic tumors in the liver, lumbar vertebrae and bilateral lung. An ultrasound-guided needle biopsy revealed a lung tumor containing melanic tissue. Subsequently, there was an evident elevation in uric acid, phosphoric acid, potassium and lactate...

To clarify the relationship between morphological changes in the corneal endothelium and ultraviolet (UV) radiation, specular microscopic examinations were performed on both eyes of 118 welders and 85 controls. The results showed: a decrease in the hexagonal cells in welders (20-29 years) in comparison with the controls (20-29) (p less than 0.05); an increase in the mean cell size of the endoth...

Ultrastructural and immunohistochemical studies of the small intestine are described in a Japanese patient with alpha heavy chain disease who had a history of colonic ulcers. Endoscopic examinations revealed multiple gastric erosion, duodenal ulcer, and a thickened, cobblestone-like pattern composed of small nodules in the duodenum and jejunum, which was similar in appearance to Crohn's disease...

This paper aims to present both intraosseous and extraosseous variant of dentinogenic ghost cell tumor as well as a review of the literature. An 11-year old female patient presented a swelling and pain in the molar area of the mandible and a 15-year-old female patient reported a complaint of swelling in the right vestibular region of teeth 12 and 13(FDI 2-digit classification system). Microscop...

The patient was a 36-year-old woman who manifested no remarkable abnormalities except headache, which suggested elevated intracranial pressure. Serum human chorionic gonadotropin and alphafetoprotein values were normal. CT and MR examinations were performed (Figs. 1 A-1 D). CT revealed a solid tumor with punctate calcification on the pineal region. MR distinctly marked the presence of the tumor...

G astrointestinal stromal tumours (GISTs) are rare and specific tumours of the gastrointestinal system that originate from Cajal cells located in different sites of the digestive tract. They may originate from the omentum and peritoneum, but are commonly located in the stomach and small bowel. These tumours are frequently small, asymptomatic and found incidentally; they may be benign or cancero...

pathological examinations of the respiratory tract of young hamsters infected with Mycoplasma pneumoniae by inhalation of aerosol were carried out for up to a maximum of 98 days after infection. Mycoplasma pneumoniae organisms were found mainly in the pharynx and larynx for the first two weeks, then they con tinued to proliferate in the main bronchi or intrapulmonary bronchi for up to 98 days. ...

cases (400). Browne dealt very fully with his subject, describing minutely the microscopic findings in a large number of postmortem examinations. There are many here to-night who will remember these addresses; but in so far as some five years have elapsed since Browne's work was last discussed, we trust that this fresh series of cases will not be devoid of interest. We have not attempted to inv...

Mantle cell lymphoma (MCL) is an aggressive type of lymphoma with frequent involvement of the gastrointestinal (GI) tract. The spectrum of GI involvement is highly variable, from clinically overt disease to the insidious disease which can be diagnosed with multiple biopsies and even electron microscopic examinations. Here a case with MCL and accompanying colon cancer without GI symptoms has bee...
