Necrosis idiopática de la cabeza femoral : estudio histopatológico, radiográfico y de fluorescencia
A comparative study is made of the histopathology, radiology and fluorescence of tetracyclin uptake in 15 cases of idiopathic necrosis of the femoral head (Ficat and Arlet Degrees III and IV) treated with substitution arthroplasty. Necrosis was seen to be multifocal in 30% of the cases studied. The limits of necrotic bone were poorly defined in ali patients; the most peripheral necrotic area presented occupied osteocytic lacunae, with a significantly increased number of empty osteocytic lacunae within apparently healthy bone. These observations, together with scant histologyc and fluo1escent evidence of reparation activity, point to a metebolic bone disease involving the entire femoral head…

Ultrastructure of one Ewing's sarcoma of bone with endothelial character and a comparative review of the vessels in 27 cases of typical Ewing's sarcoma.
An atypical variant of Ewing's sarcoma, located in the left hip of a nine-year-old girl, is discussed at optical, histochemical and electron microscopical level. The endothelial appearing cells seem to play a main role in its histogenesis. Tumoral cells of an undifferentiated blastemic nature show round nuclei and bright lucent cytoplasm, being organized in solid sheets or vascular-like profiles. Alkaline and acid phosphatases are very prominent in all tumoral cells, and some of them also show PAS positive material. Its ultrastructure demonstrates an active pinocytic capacity, cytoplasmic filaments and Weibel-Palade bodies. Simultaneously a review is performed on 27 cases of typical Ewing's…
