Resumo
A spindle-cell sarcoma (fig. 5) apparently originating from the dura (fig. 4) was found at the autopsy of a male, mulato, 17 years of age. The bones of the skull (occipital and both parietals) were penetrated and destroyed (fig. 1 and 2). The nervous tissue was not penetrated, the only change in the brain being a depressed area where the tumor was included. Metastatic nodules were found in the liver (fig. 3),hepatic lymphnodes (fig. 14), spleen (fig. 12) and suprarenal bodies (fig. 15). The structure, however, in all those different locations was that of a typical endothelioma (figs. 8, 11 and 13). The cells are of large and moderate size, of polyhedral form, with vesicular nuclei, diminutive nucleoli and clear cytoplasm. (Figs. 6 and 8). They are arranged about a central lumen which represents a rudimentary vessel (figs. 9 and 13). Other areas are composed of cells without concentric arrangement (figs. 4 and 10). In small areas, the colums of liver cells are marginated in one side by typical sinusoids, while in the other side tumor cells arranged about a narrow lumen are seen suggesting a pathological (neoplastic) sinusoid (figs. 7 and 9). The case is considered as a multiple diffuse endothelioma. The origin of the tumor is referred to the reticulo-endothelial apparatus of the liver, the spleen, the suprarenal bodies and the lymph nodes, the structure being rather uniform in those organs. In the dura, the endothelioma reproduces the structure and presents the general character of a fibroblastic sarcoma; in some places, however, the structure of endothelioma could be found (fig.6). It corresponds to the reticulo-endotheliomatosis maligna according to Puhr's grouping of progressive changes in the reticulo-endothelial apparatus which is a follows: 1. HYPERPLASTIC - 1. Mnnocytic leukemia. 2. a) Aleukemic reticulosis (Goldschmid and Isaac). b) Idiopathic sarcoma of skin (Kaposi). c) Cutaneous sarcoid (Spiegler). 3. Secretory reticulosis. a) Gaucher's disease. b) Generalized xanthomatosis. c) Spleno-hepatomegaly with lipoidic cells (Pick). II. BLASTOMATOSUS OR NEOPLASTIC - 1.
