Summary To obtain information about the role of local proliferation in the pathogenesis of dermal infiltrate in malignant cutaneous lymphomas, we determined the percentage of 3H-thymidine-labeled infiltrating cells (3H-index).A linear correlation was found between proliferative activity and clinical stage in mycosis fungoides, i.e., the 3H-index is moderately elevated in stage I and high in stage III.The 3H-index is within normal range in dermal infiltrate of Sézary syndrome, diffuse lymphocytic lymphoma, as well as in lymphocytoma benigna cutis.In parapsoriasis en plaques two groups can be distinguished: in the smallplaque variant (chronic superficial dermatitis) the 3H-index is low, whereas the large-plaque variant (prereticulotic poikiloderma) shows strong proliferative activity.Thus, determination of proliferative activity seems to give new insights into the pathogenesis of dermal infiltrate in cutaneous lymphomas.Zusammenfassung Um die Bedeutung der lokalen Zellproliferation im dermalen Infiltrat bei cutanen malignen Lymphomen zu untersuchen, bestimmten wir den Prozentsatz der 3H-Thymidin-markierten Infiltratzellen (3H-Index.Zwischen dem klinischen Stadium der Mycosis fungoides und der Proliferationsaktivität des dermalen Infiltrats besteht eine lineare Beziehung; im Stadium I ist die Proliferation niedrig, im Stadium III sehr hoch.Nicht erhöht ist der 3H-Index im dermalen Infiltrat beim Sézary-Syndrom, diffusen lymphocytischen Lymphom sowie bei Lymphocytoma benigna cutis.Bei der Parapsoriasis en plaques müssen zwei Formen unterschieden werden: bei der kleinfleckigen Form (chronic superficial dermatitis) ist der 3H-Index niedrig, während die großfleckige Form (Präretikulotisches Poikiloderm) eine starke Proliferationsaktivität aufweist.Die Untersuchung des Proliferationsverhaltens gibt neue Einblicke in die Pathogenese des dermalen Infiltrats cutaner Lymphome. 相似文献

Lymphomatoid papulosis (LyP) is a cutaneous eruption that is clinically benign but histologically malignant. To date, more than 300 cases have been published. About 10–20% of the patients develop a lymphoma. The purpose of this study was to make a clinicopathological study of 18 patients diagnosed with LyP in our hospital from 1973 to 1990, to characterize cellular infiltrates in the lesions, to find clonal populations of T-cells and to look for predictive factors of malignant lymphoma in LyP patients. Mean age was 48.7 years. The most frequent clinical lesions were papules (88.8%) followed by plaques (38.8%). The localizations were on extremities (100%), trunk (88%), face (22%), palms or soles (11%), perigenital (11%) and scalp (5%). Two patients have been free of disease for more than 5 years. IgA levels are increased in LyP patients. Neither HTLV I nor III can be considered as a cause of the LyP in any of our patients. Associated diseases were found in 6 cases (1 mycosis fungoides, 1 Hodgkin's disease, 2 anaplastic large-cell lymphoma and 2 large plaque parapsoriasis). Some types of parapsoriasis should be included in the ‘spectrum of Ki-1 lymphomas’. 52 skin biopsies were studied. 17% were type A of Willemze, 67% were type B and 15% were transitional. In 12 of the samples follicular or perifollicular infiltration was found. Follicular LyP should not be considered as a distinct type of LyP. Vasculitis is an uncommon finding in LyP. In all the cases studied, large atypical cells were CD30 +; 5/7 cases had lost CD5 and 4/5 cases had lost CD7. In one case, all T-cell antigens were negative. Cerebriform mononuclear cells were always recognized by T-cell antibodies and they were CD30 positive in only two cases. In one case there were more CD8 + than CD4 + cells. In 5 patients skin and blood samples for genetic rearrangement (beta-T) were taken. Only germinal line was found. We did not find any significant difference between those cases in which malignant lymphoma developed and those in which it did not. 相似文献

Zusammenfassung An Hand einer eigenen Beobachtung, einem 14jährigen Buben mit epileptischem Anfallsleiden, wird das Pseudolymphomsyndrom beschrieben. Dieses stellt ein eigenständiges, hydantoininduziertes Krankheitsbild dar, das mit septischen Temperaturen, pseudoneoplastischen Lymphknotenschwellungen, Hepatosplenomegalie und polymorphen Exanthemen einhergeht und weiters besonders durch eine Leukocytose mit Eosinophilie sowie Hypergammaglobulinämie charakterisiert ist. Pathogenetisch liegt ihm eine allergisch-hyperergische Reaktion auf Hydantoine zugrunde.
Pseudolymphoma Syndrome
A 14-year-old boy with an infrequently observed pseudolymphoma syndrome is reported. This syndrome consists of fever, polymorphic skin eruptions, generalized lymphadenopathy, hepatosplenomegaly, nephropathy and arthralgia. Laboratory findings include leucocytosis with eosinophilia and hypergammaglobulinaemia. It is induced by hypersensitivity to hydantoins; all abnormalities resolve on withdrawal of the offending drug.相似文献

Reactive lymphoid hyperplasia(RLH), also known as pseudolymphoma or nodular lymphoid lesion of the liver is an extremely rare condition, and only 51 hepatic RLH cases have been described in the literature since the first case was described in 1981. The majority of these cases were asymptomatic and incidentally found through radiological imaging. The precise etiology of hepatic RLH is still unknown, but relative high prevalence of autoimmune disorder in these cases suggests an immune-based liver disorder. Imaging features of hepatic RLH often suggest malignant lesions such as hepatocellular carcinoma and cholangiocarcinoma. In this report, we discuss two cases of hepatic RLH in patients with autoimmune hepatitis. We also present pathologic and magnetic resonance imaging findings, including one case utilizing a hepatocellular contrast agent, Eovist. Definitive diagnosis of hepatic RLH often requires surgical excision. 相似文献

Pseudolymphoma of the liver associated with primary biliary cirrhosis: A case report and review of literature 总被引:1,自引:1,他引:0
Toshihide Okada Hiroshi Mibayashi Kenkei Hasatani Yoshiaki Hayashi Shigetsugu Tsuji Yoshibumi Kaneko Masashi Yoshimitsu Takashi Tani Yoh Zen Masakazu Yamagishi 《World journal of gastroenterology : WJG》2009,15(36):4587-4592
We report a case of two pseudolymphomas of the liver in a 63-year-old Japanese woman with primary biliary cirrhosis. One of the lesions was found incidentally during a medical examination, presenting as a 10 mm hypodense nodule that revealed hyperdensity in the early phase and hypodensity in the late phase in computed tomography (CT) after injection of contrast medium. Retrospectively, the 10 mm nodule had first been discovered as a 4 mm nodule during CT 4 years previously. Superparamagnetic iron oxide-enhanced MRI revealed another 4 mm hyperintense nodule in segment 6 in addition to the 10 mm hyperintense nodule in segment 7. CT during arterial portography revealed two hypointense nodules. Findings with other imaging modalities such as ultrasonography, magnetic resonance imaging, and hepatic angiography were consistent with hepatocellular carcinoma. A right posterior segmentectomy was performed, and the lesions were microscopically diagnosed as pseudolymphoma. To the best of our knowledge, only 31 other cases of this disease have ever been reported, with a highly asymmetrical male:female ratio of 1:9.7. Although we could find only one case of transformation of hepatic pseudolymphoma into lymphoma in the liver, the exact nature of development from benign pseudolymphoma to malignant lymphoma is still not fully understood and cases of hepatic lymphoma need to be followed carefully. 相似文献

We report a rare case of nodular lymphoid hyperplasia in the lung. An 18-year-old woman had an abnormal shadow found on chest
radiography images. Positron-emission tomography showed an uptake of 18F-fluorodeoxyglucose in the mass lesion, with a maximum standardized uptake value of 2.4. The lesion gradually enlarged, and
surgical removal was performed. Histopathological examination of the resected lung revealed polyclonal proliferation of lymphoid
tissue, leading to a diagnosis of nodular lymphoid hyperplasia. 相似文献

A case of a 53-year-old female patient with reactive lymphoid hyperplasia (RLH), clinically designated as pseudolymphoma of the liver is described in this article. The patient was admitted to our hospital for further evaluation of hepatic tumors incidentally discovered at another hospital. Various diagnostic methods, including ultrasonography (US), computerized tomography (CT), magnetic resonance imaging (MRI) and hepatic angiography displayed three small lesions in the liver with outstanding findings consistent with hepatocellular carcinoma (HCC). Surgical resection was performed and the three lesions were microscopically diagnosed as RLH of the liver. The lesions comprised a massive infiltration of lymphoid cells with follicles and hyalinized inter- follicular spaces. Immunohistochemical examination revealed that infiltrating lymphocytes had no prominent nuclear atypia and polyclonality. RLH of the liver is a very rare condition and only twelve cases have been reported in the English literature. Majority of the reported cases were middle-aged women and about half of them had some immunologic abnormalities such as autoimmune thyroiditis, Sjogren's syndrome, primary immunodeficiency, primary biliary cirrhosis. Since they are olden clinically misdiagnosed as HCC, surgery is the choice of treatment for these patients. Although their pathology resembles malignant lymphoma, the clinical course is completely benign. The authors propose that RLH of the liver can be discriminated from HCC by its clinical features. 相似文献
