To investigate the heterogeneity of fibroblast proliferation rate depending on the depth of dermis in the psoriatic skin lesions, fibroblasts were obtained from the upper and lower dermis of the forearm skin lesions in 9 psoriatir, patients and of the comparable sites in 7 healthy persons respectively, and were cultured. The in vitro proliferation rates of the fibroblasts were calculated by measuring the efficiency af cell attachment, cell numbers on varying days of culture and the population doubling time during the 3rd passage of subculture. The results were as follows: 1, The efficiencies of cell attachment at 24 hours after seeding were not statistically different between the upper derrnal fibroblasts and the lower ones in both psoriatic skin lesions and normal skins. 2. By rneasuring the cell numbers and the population doubling times, the prolifeatior rate of the upper der mal fibroblasts was greater than that of the lower ones in both psoriatic skin lesions and normal skins and that the fibroblastic proliferation rate was significantly inereased in the psoriatic skin lesion compared to the normal skin.

We herein present a case of bullous lichen planus in a 56-year-old female. She had had a generalized eruption of lichen planus with violaceus papules and plaques. many of which had been surmounted by vesicles and bullae. The histopathologic findings of a bulla revealed hyperkeratosis, irregular acanthosis, subepidermal bulla and upper dermal band-like cell infiltration. The patient had been treated with dapsone but the lesions had not been significantly improved.

We herein presented a case of persistent variant of Grovers disease in a 83-year old male. He had a rather extensive eruption of erythematous scaly papules, which had been profusely grouped but discretely distributed over 2 years or more. The histopathologic findings of two lesions in the same patient revealed mixture of various histologic patterns, patterns resembling Dariers disease, pemphigus vulgaris, Hailey-Hailey disease and spongiosis. The ultrastructural findings of Darier pattern should be essentially similar to those of Dariers disease and also be common to those observed in the early stages of other causes of focal acantholytic dyskeratosis. The patient had been treated with topical and intralesional steroid and oral 13-cis-isotretinoin, however, the lesions had been persisted only with partial improvement of clinical appearance and reduction of pruritus.

Hepatolithiasis is said to exist when stones are present in the right or the left hepatic ducts or their tributaries. Although it is a pathophysiologically benign disease, it causes frequently serious problems-recurrent cholangitis, liver abscess, obstructive jaundice, liver cirrhosis, and sepsis - and has challenged surgeons. Until recently, its fundamental pathogenetic mechanisms have not been elucidated, but bile duct stenosis, bile stasis, and secondary infection are considered as important pathogenetic factors. Therefore, the ultimate goal of the treatment is directed to the correction of these factors. We were retrospectively reviewed 119 cases of patients with hepatolithiasis treated by various surgical methods from Jul. 1989 to Dec. 1996 at the Department of Surgery of Maryknoll Hospital, Pusan. There were 72 women and 47 men, and the mean age was 45.5 years. Thirty-nine patients (32.8%) had previous histories of operations related to biliary stone diseases - cholecystectomy (n=13), T-tube choledocholithotomy (n=21), choledochoduodenostomy (n=9), Roux-en-Y choledochojejunostomy (n=6), and transduodenal sphincteroplasty (n=1). Operative procedures were 24 (20.2%) lithotomy, 60 (50.4%) drainages, and 35 (29.4%) hepatectomies and determined by the location of the stones, the general condition of the patient, and the anatomical change (stenosis or cystic dilatation) in intrahepatic duct. Postoperative complications occurred in 33 (27.7%) patients : wound infection (n=23), atelectasis (n=5), intra-abdominal bile collection (n=3), choledochocutaneous fistula (n=2), hemobilia (n=1), and adhesive ileus (n=1). Residual stones were detected in 39 (32.7%) patients by T-tube cholangiography, ultrasonography, computed tomography. The instances of residual stones was the lowest (17.1%) for hepatectomy compared to 45.8% for a lithotomy and 39.3% for a drainage. The follow-up study showed symptom improvement in 91.5% of the patients with a hepatectomy compared to 58.3% for a lithotomy and 71.7% for a drainage which was statistically significant(P<0.05). Since incomplete stone removal in hepatolithiasis and presence of stenosis in intrahepatic duct frequently require a repeat operation or other invasive management, the authors conclude that a hepatectomy, as an initial treatment for hepatolithiasis, is a safe, satisfactory treatment where possible.

Tuberculosis of the duodenum is rare event in patients with pulmonary or intestinal tuberculoais. It is very difficult to diagnose duodenal tuberculosis because of inconaiatent symptoms and nonspecific duodenal lesioa. Although fiberoptic endoscopy has been used, there is the limitation of fiberoptic endoscopy ia diagnosingthis disease and the diagnoais require laparotomy with biopsy. Recently we experienced a case of duodenal tuberculosis with duodenoscopic findings of the submucosal tumor of duaidenum. We report a case with review of literatures.

We reviewed clinical records and histologic materials of 96 cases of metastatic skin cancer in Seoul National University Hospital from January 1973 to July 1986. The metastatic skin cancers of male were twice as many as that of female and they occurred most frequently in male at their fifties, female, forties. The most frequent primary cancers in men were carcinoma of the stomach, lung, colorectum and pancreas; in women, carcinoma of the breast, stomach, lung and uterine cervix. Cutaneous metastases from the carcinomas of the liver, uterine cervix and stomach which were many in Korea were smaller in number than that from the carcinomas of the lung and breast. Metastatic lesions were recognized before the primary tumor relatively often in carcinoma of the lung, pancreas and rarely in carcinoma of the uterine cervix, stomach. Though localizations of cutaneous metasta.sis were widespread over all body surfaces, regional areas of primary tumor were predisposed to metastasis. Metastatic carcinoma usually produced nonspecific nodules in the skin. Less commonly, some lesions of metastasis showed inflammatory or sclerotic plaque. The histologic findinga of cutaneous metastases generally mimicked that of primary tumors; nevertheless, in most instances, it was not possible to recognize the original tumor from a histologic examination of metastatic skin cancer and it was possible to classify the metastatic carcinoma only as an adenocarcinoma, a squamous cell carcinoma or an undifferntiated carcinoma.

To evaluate the prognostic predictor and clinicopathologic characteristics of the gastrointestinal (GI) mesenchymal neoplasm, we examined 75 cases of GI mesenchymal tumors surgically resected during 8 years from 1983 to 1990. Various histological parameters referrable to the prognosis, including the Ag-NORs count, were analysed. Fifty cases were followed-up for 1 to 7 years. Sixteen out of these fifty cases died during this period. The location of tumor was the stomach in 33 cases, the small intestine in 31 cases and the large intestine in 11 cases, and the tumor size was variable from 2 to 35 cm in diameter. The GI mesenchymal neoplasm appeared as an extraluminal mass in 50 cases, an intramural mass in 17 cases, and an intraluminal mass in 8 cases. Each tumor was composed of spindle or epithelioid cells, the former cell type being more common than the latter (45 vs 30 cases). Mitotic count of the tumor showed the best correlationship with the survival of patients(p<0.05), although the tumor size and necrosis appeared to have some values. The Ag-NORs count was variable and was not significantly correlated with the patient's prognosis(p>0.05). These results indicate that the mitotic count is the most valuable pathological predictor for the prognosis in GI mesenchymal neoplasms.
