We report a case of pseudosarcomatous variant of transitional cell carcinoma of the renal pelvis which showed grossly and microscopically the distinct biphasic growth patterns. Grossly, most part of the tumor showed solid growth protruding into the renal pelvic cavity as well as infiltrating into the parenchyma of lower pole. The overlying pelvic mucosa was replaced by a diffuse, papillary transitional cell carcinoma, and the solid mass was composed of pleomorphic spindle cell sarcomatoid component with frequent myxoid change and a few foci of osteoid deposit. Ultrastructural study of the spindle cells revealed epithelial differentiation featured with rich cytoplasmic organelles, basal lamina and basement membrane-like structures, although immunohistochemistry failed to detect epithelial differentiation.

Twenty cases of polypoid lesions of the gallbladder were reviewed. Seven were benign lesions. Among them, there were 4 (20%) adenomas and 3 (15%) adenomatous hyperplasias. All of the benign lesions were less than 1 cm in diameter. Thirteen cases involved a carcinoma of the gallbladder, of which 92% were more than 1 cm in diameter, 76.9% were over 60 years of age, and 38.5% were associated with gallstones. The accuracy of the preoperative ultrasonographic diagnosis of the polypoid lesions of the gallbladder was 80%. The spread and the size of the tumor showed a close correlation. Therefore, the size of the tumor is a vital indicator for the treatment of polypoid lesions of the gallbladder; lesions between 0.6~1 cm in diameter should be followed up by ultrasonography. An operation may be considered if stones are present. Lesions bigger than 1 cm should be resected since malignancy can not be excluded.

BACKGROUND: Hypertrophic scars and keloids are prevalent and emotionally debilitating dermatologic diseases. Various treatment modalities have been advocated to treat hypertrophic scars and keloids. OBJECTIVE: This study prospectively assessed the safety and efficacy of using intense pulsed light (IPL) on scars that originate from surgery. METHODS: A total 22 patients with surgically induced hypertrophic scars and keloids were treated with IPL. Treatment was administrated at 4-week intervals, with an average of 3.5 sessions (range=1~10). The scars were evaluated for pigmentation, pliability, height, vascularity, pain and pruritus by using the modified Vancouver Scar Scale (MVSS). The subjective assessment of satisfaction was scored by the patients on a 25% increment of satisfaction scale. Evaluations were performed monthly during the follow-up period. RESULTS: There was overall clinical improvement for the appearance of the scars. Although statistically significant improvement was not shown (p=0.47), the average MVSS showed a trend for favorable effects on the scars with the successive IPL treatments. The patients who had higher baseline MVSS (> or =10) demonstrated statistically significant improvements with the successive IPL treatments (p<0.05). The degree of the patient's satisfaction also improved with the treatment for all of the patients (p<0.05). The adverse effects were negligible. CONCLUSION: IPL is one of the effective, safe methods to improve the clinical appearance of surgically induced hypertrophic scars and keloids and this treatment had high patient satisfaction and relatively few side effects.

A pancreatic pseudocyst is a relatively rare complication of pancreatitis. Various factors, such as inflammatory process or trauma, are among the possible cause of pancreatitis. A pancreatic pseudocyst is often defined as a localized collection of pancreatic juice in the retroperitoneal area surrounded by a fibrous membrane devoid of an epithelial lining. The hospital records of 52 cases of pancreatic pseudocyst treated at Kyungpook National University Hospital from 1976 through 1994 were reviewed and analysed. The results are as follows : 1) The age distribution of these cases showed that 57.7% occurred in the 3rd and the 4th decades. The male to female ratio was 3.7 : 1 2) The etiology of the pseudocysts was pancreatitis in 46.2% of the cases and trauma, unknown etiology, pancreatic cancer and hyperlipidemia, in that order, in the other cases. 3) Abdominal pain was the most common symptom (86.4%); a palpable mass (65.4%), abdominal tenderness (65.3%) also occurred. 4) Abdominal C.T. and Ultrasonogram has a diagnostic accuracy as 100%, and U.G.I. showed a diagnostic accuracy of 76.5%. 5) Among the 52 cases, 30 cases received surgical treatment 13 cases were treated by percutaneous catheter drainage. 6) With respect to the operative procedure, internal drainage was performed in 18 cases (60%), external drainage in 8 cases (26.7%), excision in 3 cases (10.0%), and O & C in 1 case (3.3%). 7) Thirteen percutaneous catheter drainage procedures were performed, and the success rate was 92.3%.

Carcinoid tumor of stomach continue to interest clinician because of the rarity and difficulty in diagnosis clioically with infrequent classical carcinoid syndrome. Recently, we experienced a case of gastric carcinoid with hemetemesis and melena. We feel that this case is an instructive example of the fascinating variety of entities which can result in massive upper gastrointestinal bleeding. So we present this case with s review of relevant literatures.
