Autoimmune findings resembling connective tissue disease in a patient with Castleman's disease.

Multicentric angiofollicular lymphnode hyperplasia (multicentric Castleman's disease) may be associated with acute phase reaction and several autoimmune features. Since lymphadenopathy is a common feature in connective tissue disease, a clear distinction between the different disease entities may be difficult. We describe a 26-year-old male patient with predominant cervical lymphadenopathy, hepatosplenomegaly and polyserositis, diagnosed as collagen disease. He showed several autoimmune features including autoimmune haemolytic anaemia, cryoglobulinaemia, positive antinuclear and anti smooth muscle antibodies, serum immune complexes and a sensorimotor polyneuropathy. Under immunosuppressive …

In-witro-NMR-Spektroskopie an gesunden, mastopathisch veränderten und karzinomatös befallenen Brustdrüsen-gewebsproben, korreliert mit histologischen Befunden

Es wurden bei 57 Patientinnen mit klinischem Verdacht auf Mammakarzinom 121 Gewebeproben entnommen und mittels der 1H-NMR-Spektroskopie bei 300 MHz in vitro nach Korrelation mit histologischen Befunden untersucht. Im interessanten Spektralbereich zwischen 2,7 und 4,1 ppm wurden starke Signale beobachtet, die Fett, (Phosphoryl-)Cholin, Kreatin(-phosphat) sowie Karnitin zugeordnet wurden. Weiterhin konnten mit hoher Regelmasigkeit 8 schwachere, zum Teil uberlappende Signale der Substanzen Glukose, Glyzin, Threonin, Serin, Inositol und Saccharose nachgewiesen werden. Hierbei wurden Linienintensitaten uber ein iteratives Fitprogramm bestimmt. Uber deren Quotienten konnten unterschiedliche Geweb…

Das basaloide Plattenepithelkarzinom (BSC) der Mundschleimhaut

The basaloid-squamous carcinoma (BSC) that was first described in 1986 by Wain et al. for the head and neck region is a rare distinct variant of squamous cell carcinoma (SCC). The cardinal histopathologic feature is a biphasic cellular pattern of basaloid and squamous components. BSC has been confused with solid adenoid cystic carcinoma (ACC). Although the number of reported cases is small, BSC appears biologically virulent, with a propensity to aggressive local behavior, early regional and distant metastasis, and subsequent poor survival. We report the clinicopathological characteristics of 4 new cases and compare their immunohistochemical features with those of solid ACC and conventional …
