Xanthogranulomatous cholecystitis is a rare form of inflammatory disease of the gall bladder and was first described in 1970 by Christensen and Ishak as fibroxanthogranulomatous inflammation of the gall bladder. Recently authors experienced three cases of xanthogranulomatous cholecystitis, two of which were erroneously diagnosed as malignant tumor in preoperative clinical and radiological examinations. Grossly, the gallbladders were enlarged and the walls were thickened with yellowish granular necrotic areas ranging from a few millimeters to 1.0 cm in diameter. Microscopically, all of three cases showed diffuse infiltration of the foamy histiocytes containing bile pigments and mononuclear leukocytes associated with fibroblastic proliferation and foreign body reactions. The pathogenesis of the xanthogranulomatous cholecystitis is uncertain, but opinion favours an inflammatory response to extravasated bile probably, from ruptured Rokitanky-Aschoff sinuses. Three cases of xanthogranulomatous cholecystitis with brief review of literature are presented.

Meningiomas are usually thought of as firm solid tumors and most standard references make no mention of cystic meningiomas. Although several cases of cystic meningioma have been reported in the literature and their neuroradiological features discussed, the rarity of this entity makes its preoperative diagnosis difficult. Recently, the authors encountered a case of cystic meningioma, which was thought as ependymal cyst or infarction, preoperatively. In this report the authors discussed its clinical, neuroradiological and pathological characteristics with brief reviews of the literature.

Cutaneous leiomyoma is a benign tnmor originating from smooth muscle fibers which are derived from arrector pili muscle, media of blood vessels and dartoic muscle of scrotum, vulvar, or nipple. It is classified into 3 types according to the site of origin, namely pilar leiomyoma, angioleiomyoma and genital leiomyoma. Leiomyoma of the nipple is the less kquent type of cutaneous leiomyoma. We report a case of cutaneous leiomyoma on the nipple in a 53-year-old man.

Plasma cell cheilitis is a rare inflammatory disorder which shows a dense, band-like infiltrate of plasma cells in the upper dermis. Although the histological picture is shared with other diseases of the lips, plasma cell cheilitis is not associated with any known dermatoses. Some authors have shown the effectiveness of topical or intralesional corticosteroids; however, there have been many reports describing poor therapeutic response to topical steroids. We de-scribe two patients with plasma cell chielitis whose clinical condition responded rapidly to the intralesional injection of corticosteroids.

It is the existence of a polarized distribution of ion transporters and channels which is thought to underlie the vectorial salt movement. The present study was performed to examine the expression and polarized distribution of Na+-K+-ATPase isoforms believed to be essential for salivary secretion in the rat salivary gland using immunohis-tochemistry. Na+-K+-ATPase alpha1 subunit immunoreactivity was prominent in the granular convoluted duct of the submandibular gland, and striated and excretory duct of three major salivary glands. The submandibular ganglion and postganglionic nerve fiber exhibited moderate immunoreactivity, whereas the intercalated duct and acinar cells of major salivary gland were weakly labeled. Na+-K+-ATPase beta1 subunit immunoreactivity was prominent in the granular convoluted duct of the submandibular gland, intercalated duct of the sublingual gland, acinar cells of the parotid gland, and striated and excretory ducts of major salivary gland. The submandibular ganglion, intercalated duct of the submandibular gland, and acinar cells of the sublingual gland exhibited moderate immunoreactivity, whereas acinar cells of the submandibular gland and intercalated duct of the parotid gland were weakly labeled. In these segments, alpha1 and beta1 immunoreactivity was expressed at the basolateral pole, and no apical expression was detected. These results suggest that major salivary glands are comprised of at least two structurally unique Na+-K+-ATPase isoforms, which are participated in primary saliva formation and transport.

Collateral ligament injury of the IP joint of the fingers are common and almost always occurs at the PIP joint. But the rupture of collateral ligament is often miss-diagnosed as sprain and it's seriousness is often underestimated, of such injuries frequently result in prolonged and even permanent disability of the injured fingers. During the period of Sept. 1986 to Aug. 1988, 16 collateral ligament injuries in 15 patients were treated surgically at Holy Family Hospital, Bu Cheon and following results were obtained: 1. Among 15 patients, 14 were male and the age was 32.1 years on an average. 2. The 7 cases had associated injuries in the same fingers. 3. In 6 cases ligaments were ruptured at the proximal attachment, in 5 at the distal attachment, and in 5 at the ligament substance. 4. Average range of joint motion at the final observation was 69.2°. The average flexion contracture was 9.3°, and the average further flexion was 78.5°. 5. The flexion was limited more than the average when the ligament was ruptured at the insertion(66°) and when there were other associated injuries in the same finger(58.1°). The extension was limited more than the average when the ligament was ruptured at the substance(18°) and when patients were over the age of 31 years(12.5°).

Magnetic resonance imaging has been recognized as more suitable method than radiography and bone scan for the early detection of avascular necrosis of the femoral head. Segmental collapse is the most important factor in the prognosis of patient with avascular necrosis. The authors studied the appearance of avascular necrosis with both radiography and magnetic resonance imaging and then determined which lesions remained unchanged, progressed or led to collapse, as determined wih follow-up radiography in the 61 radiographically negative avascular necrosis of the femoral heads. 1. The necrosis-progression rates according to the extent were 36% in Extent A, 83% in Extent B, and 93% in Extent C. The necrosis-progression rate was significantly correlated with the extent of necrosis initially involved. 2. The necrosis-progression rates according to the location were 37% in Type I, 70% in Type II, and 95% in Type III. The necrosis-progression rate was significantly correlated with the weight bearing area of necrosis initially involved. 3. There was no correlation between necrosis-progression rate and signal intensity. 4.All of the cases which had combinations of the Extent C, and Type III location showed progression. 5. None of the femoral heads that had been treated at the radiographically negative stage was collapsed, but 35% of the femoral heads those had been treated at the radiographically positive stage were collapsed. 6. In the cases which were treated early, all of the Extent C, Type III were collapsed, but none of the Extent A, Type I were collapsed. In conclusion, magnetic resonance imaging is useful for evaluation of the risk of collapse or for anticipation of the prognosis of the affected hip joint as well as for the early diagnosis of radiographically negative avasular necrosis of the femoral head.
