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

Lymphocytoma Cutis is a rare pathology affecting mainly the head and neck. Because of its rarity, the authors describe a
clinical case in which the face was severely affected. Histological examination was conducted, and surgical management for
functional eyelid improvement was prescribed. 相似文献

Summary A 47-year-old male patient suffered from recurrent myalgia, induced by fasting or physical exercise. Later, he developed progressive muscular weakness. Serum levels of creatine phosphokinase (CPK) were elevated to approx. 400 U/l. Muscle biopsies showed lipid storage myopathy and signs of acute fiber necrosis, muscle carnitine was decreased to below 20% of controls, carnitine palmitoyl transferase (CPT) activity was normal. Carnitine was also moderately decreased in a liver biopsy and in plasma. Urine excretion of carnitine was low, no elevation of short-chain dicarboxylic acids could be found. The patient was also found to suffer from a lymphocytic malignant non-Hodgkin lymphoma, a monoclonal immunoglobulin (Ig) G-k in plasma and lymphocytic infiltration of bone marrow were demonstrated. At that time no evidence had been obtained to indicate that these two diseases could be related to each other. Autoantibodies against skeletal muscle could not be demonstrated. Absorption of L-carnitine p.o. was normal, however, plasma levels of carnitine fell again rapidly. Administration of 3 × 2 g L-carnitine per day normalized the patient's plasma carnitine levels and led to an increase of plasma short-chain acylcarnitine and ketone bodies, particularly-hydroxybutyrate (B-HOB). However, no significant clinical improvement could be seen. Additional application of prednisone led to normalization of CPK serum levels.Abbreviations AST
