We report a case of a morphologic variant of dermatofibroma. A coin sized, brownish, shinny, somewhat fibrotic pedunculated tumor in a 39-year-old male was diagnosed as a sclerosing hemangioma, a type of dermatofibroma histopathologically. Its dome shape morphology was unusual in comparison with the typical morphology of dermatofibroma that we know.

We report a pigmented follicular cyst (PFC) in a 40-year-old male manifestated clinically as pigmented nevus. Histopathologic findings revealed an infundibular cyst in the mid dermis containing a small amount of keratinous material. The cystic wall consisted of four or five layers of squamous epithelium with a granular layer with abundant keratohyaline granules and the cyst wall contained one hair follicle. It must be differentiated from other pigmented lesions of over-lying skin such as eruptive vellus hair cyst, apocrine hydrocystoma and melanocytic nevus coexistance of an epidermoid cyst. Surgical excision and histopathological examination are necessary for an accurate diagnosis in pigmented lesions.

Bartter's syndrome is a rare tubular disorder characterized by hypokalemic, hypochloremic metabolic alkalosis, hyperreninemic, hyperaldosteronism, hyporesponsiveness to pressor agents and juxtaglomerular apparatus heperplasia. We report a case of Bartter's syndrome of a 5 month-old male infant with subdural hematoma who was confirmed by characteristic clinical, laboratory findings and kidney biopsy.

Hypertrophic cardiomyopathy has been a well-known genetical transmitted disease entity with the advance of echocardiography. We have recently experienced a family with hypertrophic cardiomyopathy proved by noninvasive methods including chest x-ray,, electrocardiography and echocardiography. The propositus of this family was a 21 year-old solier who was admitted because of exertional dyspnea during military exercise. Both he and his sister had severely affected hearts with typical echocardiographic findings, asymmetrical septal hypertrophy(ASH) and systolic anterior motion of the anterior mitral leaflet(SAM). The clinical study is reported with the concerned literatures.

Avascular necrosis of the carpal lunate (Kienbock's Disease) was first described by Peste in 1843. It's etiology is still unknown. Since Lippman, in 1949, there have been many operative treatments for this disease but they had many complications and technical difficulties. The treatment of Kienbock's disease by resection of the lunate and replacement with fascia lata through the dorsal approach is very simple in operation method and its results were satisfactory in follow up study for postop 12, 18 months. We report two cases of Kienbock's disease with brief review of literature.

In order to study the regional distribution and relative frequency of the immunoreactive endocrine cells in the pancreatic islets of the Mongolian gerbil, pancreatic sections of Meriones unguiculatus were immunostained using an immunohistochemical (PAP) method with four types of specific antisera against insulin, glucagon, somatostatin and human pancreatic polypeptide (PP). The pancreatic islets were subdivided into three portions (central region, mantle zone and peripheral region) according to their composition of immunoreactive cells. Spherical to spindle shaped insulin, glucagon, somatostatin and PP-immunoreactive cells were observed in this study. Insulin-immunoreactive cells were present in the central regions with high frequency, and a few of these cells were also demonstrated in the mantle zones. Glucagon-immunoreactive cells were mainly restricted to the mantle zones. However, rare examples were found in the peripheral regions. As for the glucagon-immunoreactive cells, somatostatin-immunoreactive cells were detected in the mantle zones and peripheral regions with moderate and rare frequencies, respectively. PP-immunoreactive cells were found in the mantle zones and peripheral regions with rare and moderate frequencies, respectively. In the mantle and the peripheral regions, cytoplasmic process of glucagon-, somatostatin- and PP-immunoreactive cells were intermingled. In conclusion, the regional distribution of endocrine cells in the pancreatic islets of Mongolian gerbil was found to be similar to that of other mammals, especially other rodents, except for the topographical different distribution of somatostatin which differs that of other rodents.

The regional distribution and relative frequency of some endocrine cells in the principal pancreatic islets of two teleosts, Silurus asotus Linne (Siluridae) and Siniperca scherzeri Steindachner (Centropomidae), which have similar feeding habits, were observed using specific antisera against insulin, glucagon, somatostatin and bovine pancreatic polypeptide (bovine PP) using the peroxidase antiperoxidase (PAP) method. Spherical to spindle shaped cells were demonstrated in the principal pancreatic islets in both species of teleost fishes. However, they were not detected in the exocrine portions nor the pancreatic ducts. Insulin-immunoreactive cells were located in the central regions of the principal pancreatic islets at high frequency in both species. Glucagonimmunoreactive cells were restricted to the peripheral regions of the principal pancreatic islets in both species. They formed a mantle zone in the peripheral regions of Silurus asotus with moderate frequency, and occupied a narrower mantle zone in Siniperca scherzeri with moderate frequency. In addition, glucagonimmunoreactive cell cores were also found in the peripheral zone of some principal pancreatic islets of Siniperca scherzeri. Somatostatin-immunoreactive cells were dispersed in the central zone of the principal pancreatic islets of Silurus asotus with moderate frequency, but were located in the peripheral regions with low frequency in Siniperca scherzeri. Bovine PPimmunoreactive cells were found in the peripheral region and the mantle zone of the principal pancreatic islets with low and rare frequency, respectively in both species. In conclusion, the regional distribution and relative frequency of endocrine cells in the principal pancreatic islets of Silurus asotus showed general patterns similar to those of other teleostean fishes. But, some speciesdependent distributional patterns and/or relative frequencies, particularly in glucagon-, somatostatin- and bovine PP-immunoreactive cells, were detected in the principal pancreatic islets of Siniperca scherzeri

PURPOSE: Three-dimensional(3D) magnetic resonance(MR) projection imaging was evaluated as a noninvasive alternative to direct cholangiography for the assessment of its reliability in patients with obsructive jaundice. METHODS AND MATERIALS: A heavily T2-weighted gradient-echo sequence(PSIF) was used for 3D MR projecion imaging of the biliary system in five healthy volunteers and 25 patients with obstructive jaundice. The 3D images of the bile ducts were formed by stacking consecutive coronal MR images obtained with a fast imaging method to a maximum-intensity projection algorithm. RESULTS: In the volunteers, MR cholangiography could demonstrate the anatomy of the biliary tract in only two subjects. The extrahepatic and intraheparic bile ducts were well visualized in 23 patients with obstructive jaundice. The leve of obstruction and the grade of dilatation were dipicted with MR cholangiography in all cases. And the cause of obstruction could be determined with MR cholangiography in 18 cases, MR cholangiography was successful in two patients in whom ERCP failed. The gallbladder or dilated pancreatic duct not demonstrated by means of direct cholangiography was demonstrated with MR cholangiography in six cases.
