1.Cystic Struma Ovarii Mimicking Adenomatous Goiter of the Thyroid.
Korean Journal of Pathology 1997;31(7):692-694
Struma ovarii, the most common monodennal teratoma of the ovary, causes diverse problems in differential diagnosis. The literature on the pathology of struma ovarii has focused principally on the problem of formulating criteria of malignancy. In contrast, unusual gross and microscopic features of struma ovarii and its resultant problems in differential diagnosis have received relatively little attention. We report an ovarian teratoma which was almost entirely cystic, causing the diagnosis of struma to be overlooked. The removed ovarian tumor showed all the features of adenomatous goiter of the thyroid gland. The lining epithelium of the cysts was frequently flattened, and the follicles in the cyst wall were few and atrophic. The patient was a 58-year-old woman who was found to have an ovarian tumor by routine monographic examination

Sarcomatoid renal cell carcinoma is an uncommon tumor that has to be distinguished from renal carcinosarcoma. We have described three cases of sarcomatoid renal cell carcinoma showing different clinical and light microscopic features. An ultrastructural study of the tumor cells from the sarcomatoid area revealed frequent desmosomal junction, confirming the epithelial nature of the neoplasm. All three cases showed an aggressive clinical course and tended to invade adjacent organs or tissues. We believe that an histological and immunohistochemical examination in conjunction with an electron microscopic examination are necessary to diagnose sarcomatoid renal cell carcinoma.

Cerebral amyloid angiopathy (C.A.A) is characterized by the extracellular amyloid protein deposition in the vessel walls of the brain and meninges. It has been estimated to account for 5 to 10% of all primary, nontraumatic brain hemorrhage. We report two cases of C.A.A causing nontraumatic intracerebral hemorrhage in the frontal lobe. The first case was a 60-year-old female who was admitted for the left hemiplegia and dysarthralgia. Brain CT revealed right frontal lobe hemorrhage. The second case was a 72-year-old male who was admitted for amnesia and gait disturbance. Clinical impression was Alzheimer's disease. Brain MRI revealed multifocal small hemorrhage in the right frontal lobe. Microscopically, both cases showed dilated small arteries of superficial cortex and meninges with hyalinization. Some vessels showed microaneurysm and fibriniod necrosis. Congo-red stain also exhibited birefringence under polarized light. There was no evidence of Alzheimer's disease.

PURPOSE: Emphysematous pyelonephritis is a rare, life threatening infection of kidney and the pennephric space, characterized by the production of gas within the renal parenchyma. The aim of this study is to analyze the clinical and radiologic characteristics of emphysematous pyelonephritis. MATERIALS AND METHODS: We reviewed 7 cases of the emphysematous pyelonephritis. Six patients had plain abdominal radiographs, ultrasonograms and abdominal CT scans. Only one patient had plain radiograph and ultrasonogram. In 5 operated cases, CT findings were compared with surgical records. RESULTS: Plain radiographs showed characteristic diffuse mottling of gas in renal fossa. On sonogram, intrarenal gas was identified as echogenic loci with dirty shadows. CT scan showed inflammatory mass with gas and fluid levels in adjacent to the kidney. CT findings corresponded relatively wall with the surgical findings in regard to disease extent. CONCLUSION: lntrarenal gas in appropriate clinical setting is highly specific for emphysematous pyelonephritis. CT is the most sensitive method for demonstrating the disease extent as well as specific diagnosis.

Laser in situ keratomileusis[LASIK]for myopia reduces the risk of corneal haze but adds to the risk of flap complications. We assessed the incidence of flap complications overall, the management, the impact of the complications on best corrected visual acuity[BCVA], and the trend in these complications during the surgeon's learning curve in the series of 621 eyes undergoing LASIK.Twenty[3.2%]of 621 eyes had flap-related complications.The incidence of intraop-erative complications was fourteen eyes[2.2%], and it included irregular keratectomy in ten eyes[1.6%], incomplete keratectomy in four eyes[0.6%].The incidence of postoperative complications was six eyes[1.0%], and it included epithelial ingrowth in five eyes[0.8%], and diffuse lamellar keratitis in one eye[0.2%].There weren't grave complications such as infectious keratitis or corneal perforation.There was no change between preoperative and postoperative BCVA in seventeen eyes[85%].No eye lost 2 or more lines of BCVA because of flap complications. In conclusion, flap complications after LASIK were relatively uncommon, and rarely lead to a permanent decrease in visual acuity.Physician experience with the microkeratome and the careful handling of the corneal flap may be important to decrease the incidence of flap mplications.But even though it occurs, proper management and treatment will result in good surgical outcomes without grave visual impairment.
