The fine structure of capillary hemangiomas from the skin of six young adults was investigated. All the vessels had non-fenestrated endothelial cells. Their intercellular junctions had tight junctions, but desmosome-like structures were also present. Read More

Fibrous long-spacing (FLS) collagen is a distinct ultrastructural form of collagen present in normal tissue, various tumors, and tissues degraded by bacterial collagenases in vivo and in vitro. An association between FLS collagen and bacillary angiomatosis has not been previously described. Six cases of bacillary angiomatosis, including one autopsy case with disseminated disease, were examined ultrastructurally. Read More

Although the classification of "Ullman's universal angiomatosis" has not yet been completely defined, the authors estimed it interesting to report an observation which may fall into this denomination. This observation concerns a generalized cavernous angiomatosis differing from hereditary hemorrhagic telangiectasia (Rendu-Osler type) with its conventional skin and mucous membrane manifestations and its visceral forms. The patient presented cutaneous and probably digestive generalized cavernomatosis related to blue rubber bleb naevus. Read More

Weibel-Palade bodies were studied in endothelium in human tumours by transmission electron microscopy of ultrathin sections. In addition to individual Weibel-Palade bodies lying in the cytoplasm, one structure was observed which was interpreted as a Weibel-Palade body and in which the limiting membrane was in continuity with the plasmalemma, suggesting exocytosis. The interior of non-exocytosing Weibel-Palade bodies was generally rather dense and the microtubular inclusions well delineated. Read More
