BACKGROUND: Generally, there are few problems in the diagnosis of Paget's disease(PD) using the H&E stain. However, the differentiation of PD from the clonal type of Bowens disease and superficial spreading melanoma in situ that shows pagetoid spreading of tumor cells, may present diagnostic difficulties. In addition, the specia1 stains used for demonstrating the presenee of Pagets cells, such as PAS and mucicarmim, are non-specific and not always sensitive. So, inenunohistochemical stains with monoclonal antibodies against various antigens may be helpful for differentiating PD from ather morphologically similar skin lesions. OBJECTIVE: The purpose of this study was to investigate the diagnostic accuracy of immunohisto- chemical staining for diagnostic use in PD. METHODS: Immunohistochemical stains used in the biotin streptavidin amplificxl technique with monoclonal antibodies to several low rnolecular weight cytokeratin(CK)s, EMA and CEA, were performed on formalin-fixed, paraffin-embedded tissue. Twelve cases of PD(10 cases of extranmmmary PD and 2 cases of mammary PD), five cases of superficial spreading melanoma in situ and five cases of Bowens disease were investigated. RESULTS: The results were as follows. 1. Positive reactions with variable intensity using CK7, CKS, CK19 were seen in all cases(100%) of PD and the. staining intensity tor CK7 or CK19 was stronger than that of CKS. 2. Of the 12 cases of PD, both CK18 and CAM5.2 staining showed positivity in 11 cases(92%). 3. EMA and CEA staining showed positivity in 10(83%) and 9(75%) of 12 cases, respectively. 4. Some Pagets cells were negative for CK8, CK18 and EMA, although other positive cells were observed in the same sections. 5. All antigens were consistently negative in all cases of Bowens disease and superficial spreading melanoma in situ. CONCLUSION: The results show that moaoclonal antibodies to low molecular weight CKs are more sensitive than EMA or CEA in the demonstration of Pagets cells. Moreover, among the low molecular weight CK series, CK7 and CK19 are most useful for their high sensitivity and intensity.

The frozen section technique is a means of intraoperative pathological diagnosis, and a procedure of great value to the surgeon. This method should be accurate, rapid and reliable. This method serves useful purposes, such as determining the presence of tumor, its type (especially whether it is benign or malignant), the adequacy of a biopsy of a suspected lesion, and the conditions of the surgical margins. But, it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations, and the accuracy of the frozen section method and the materials studies was total of frozen section diagnosis of 809 cases was 98.1% with 0.5% of false negative, 0% of false positive 0.5% of incorrect histological diagnosis or grading errors, and 0.9% of deferred cases. The tissues submitted were lymph node, gastrointestinal tract, skin subcutaneous tissues in decreasing oder of frequency. The false positive case is not present, while the false negative cases were 4.

This study was carried out to investigate the intricate mechanisms of intraalveolar fibrosis, leading to the alveolar structural remodeling, of rat lungs treated with paraquat. Sixty-three male Sprague-Dawley rats, maintained on a stock diet, weighing 200.0 gm, average, were divided into 4 experimental groups. Group 1. Control group (10 rats). Intraperitoneal injections of 2-4 ml normal saline only. Group 2(13 rats). 10, 20, 25, 30 and 40 mg per kg of body weight was administered intraperitoneally. Animals were sacificed 5 hours. 1 and 3 days after paraquat treatment. Group 3(16 rats). 20, 25, 30 and 40 mg per kg of body weight was administered to the animal, and animals died 2-5 days after paraquat administration. Group 4(24 rats). The same amount of paraquat was administered to the animal as in the group 2. Animals were sacrificed 1, 2, 6, 8 and 10 weeks after paraquat treatment. Sacrificed animal lung was examined by gross, light-microscopic, immunohistochemical, ultrastructural observation, along with cellular and chemical analyses of bronchoalveolar lavage fluid. The results were as follows: Grossly, 6 rats of chronic stage (1-10 weeks survival) developed multiple wedge-shaped scars on both lungs. These scars were situated mainly along the bronchial trees, blood vessels and subpleural regions. Light microscopically, the salient features found of the chronic stage lungs were intraalveolar fibrosis. Intraluminal buds or polypoid masses projecting into the alveolar lumen and ducts. Elsewhere, loose connective tissue masses were found to fuse together to alveolar wall, obliterating the alveolar spaces with resultant severe alveolar structural remodeling. Immunohistochemically, fibronectin was found in the center of intraalveolar buds and polypoid mass, projecting into the alveolar lumen, and in the adjacent proliferating alveolar macrophages. An attempt to measure the amount of fibronectin in the bronchoalveolar lavage fluid failed. Electron microscopically, the chronic stage lung revealed marked proliferation of both alveolar macrophages and fibroblasts in the alveolar spaces, the latter containing actin-like microfilaments and collagen fibers arranged in bundles and spirals. In areas, myofibroblasts and smooth muscle cells also present. Cellular analysis of the bronchoalveolar lavage fluid in chronic stage lungs revealed no significant findings. It can be concluded, therefore: That intraalveolar fibrosis of the paraquat-treated lungs of the rat is probably mediated by intraalveolar migrations of the interstitial cells, the main task force being the connective tissue cells, passing through the defects created in the epithelial lining surface to its basement membrane, which were inflicted upon the alveolar wall by paraquat toxicity. Fibronectin, released by activated alveolar macrophages, may be responsible for the migrations of fibroblasts and myofibroblasts into the alveolar spaces to form the intraalveolar fibrosis with subsequent alveolar structural remodeling,

Infantile myofibromatosis is an uncornmon, benign, self-limiting, localized or generalized process, probably of hamartomatous origin, which consists to a large degree of cells having the characteristics of myofibroblasts and sometimes of pericytes. Both solitary and multicentric forms occur. Most lesions are present at birth or in early infancy, and some are familial in origin. A female newborn presented with a firm, round, red colored, 3 x 3 cm sized tumor with central necrosis on the left chest. Histological examination revealed well-circumscribed nodules consisting of short bundles of plump, spindle shaped cells displaying staining characteristics intermediate between fibroblasts and smooth muscle cells. The tumor was immunoreactive for actin but did not stain for desmin. A Follow-up examination at the age of 3 months revealed a moderate degree of spontaneous regressior of the lesion.

BACKGROUND: The high level of susceptibility of patients with liver cirrhosis (LC) to septicemic infection is thought to be due to decreased reticuloendothelial function and irnpairment of several components of cell mediated and humoral immunity. It is well known that LC may cause many characteristic skin changes including jaundice, spider angioma, palmar erythema, xanthelasrna and nail changes such as clubbing and white nails. OBJECTIVE AND METHODS: During a 7 month period frorn April to October 1995, 100 patients who had been diagnosed as having LC were evaluated for the duration of their LC, the associated diseases they had apart from LC and various skin manifestations. Also, we performed the tuberculin test in 20 patients with LC and evaluated the correlation of the tuberculin test with severity of LC divided into 3 groups according to the Childs classification. RESULTS: The results are summarized as follows ; 1. The most frequent duration of LC was under 5 years (74%). 2. The most common associated disease of patients with LC was upper GI bleeding including esophageal varix (24 cases). Also, diabetes mellitus (13 cases) and hepatic coma (11 cases) were observed. 3. Jaundice (82 cases) was the most frequent skin rnanifestation of patients with LC. In addition, vascular changes (81 cases) and various nail changes (69 cases) were observed. Onychomychosis was the most common nail change of patients with LC. 4. 60% of the patients who were given the tuberculin test showed anergy, and the frequency of anergy increased in proport on to the severity of LC. However, it was not significant statistically (p> 0.05 ). CONCLUSIONS: Some of the skin manifestations help in the diagnosis of LC. Also, increased frequency of tuberculin test anergy in proportion to the severity of LC is thought to be related to decreased cell mediated immunity, although statistically it is not significant.
