Abstract

Einleitung: TP53 Genmutationen induzieren eine nukleäre Akkumulation von TP53, die immunhistochemisch(IHC) nachgewiesen werden kann. Bei anderen soliden Tumoren sind TP53 Mutationen aber nur in 50-65% der IHC positiven Tumore nachweisbar, während dieser Zusammenhang beim ACC bisher nur[for full text, please go to the a.m. URL], 128.

Abstract

A case of a 70-year-old man presenting with exsudative enteropathy due to light-chain-associated amyloidosis is reported. The diagnosis of systemic mastocytosis associated with IgG/lambda plasma cell myeloma and secondary generalised amyloidosis was carried out by morphological evaluation of bone marrow biopsy. The c-kit point mutation D816Y was detected by molecular analysis. Two years before, a cystadenolymphoma of the left parotid gland had been removed. A moderate increase of loosely scattered spindle-shaped mast cells, a subpopulation of them expressing CD25, an antigen that is not expressed by normal or reactive mast cells, was shown by retrospective analysis carried out on an intraparotideal lymph node. The c-kit mutation D816Y was shown by the molecular analysis of the lymph node. In summary, the notion that systemic mastocytosis may very rarely be associated with B cell neoplasms and that neoplastic mast cell infiltrates may be obscured because of only a minimal increase of atypical mast cells, which are outnumbered by other non-neoplastic cells in the same tissue, is supported by this case. This finding was preliminarily termed "occult" mastocytosis.

Abstract

Within a series of 22 irradiated GH-producing adenomas we studied by light microscopical and morphometrical means the grading of nuclear pleomorphism, the proportion of densely granulated cells, the number of mitoses, multinuclear cells, necrotic or necrobiotic cells, and the degree of fibrosis in comparison to non-irradiated tumours. By electronmicroscopical morphometry we investigated the changes in area, circumference, area percentage, and number of intracellular structures. The rate of necrobiotic cells and the grade of nuclear pleomorphism were significantly higher in the irradiated tumours. The fibrotic areas were larger. No differences were observed in the degree of granulation and the rate of multinuclear cells. Mitoses were found in only one tumour. Within the group of the well-differentiated adenomas the areas and circumferences of the nuclei, nucleoli, mitochondria, immature secretory granules, and secretory granules increased significantly. The area percentages of the nuclei, mitochondria, immature secretory granules, and secretory granules increased as well. The mitochondria, Golgi-fields, and the rough endoplasmatic reticulum decreased in number. The undifferentiated adenomas changed almost in the same significant way. To us most of these changes are a sign of irradiation damage. The enlargement of intracellular structures could be a sign of an increased rate of secretory activity.
