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

Immunofluorescence staining of cultured human umbilical vein endothelial cells has shown the presence of von Willebrand protein in the perinuclear region, in small rodlike structures through the cytoplasm, and on filaments of the extracellular matrix. Nonendothelial cells showed no staining with anti-von Willebrand protein antiserum. At the light microscope level, immunoperoxidase treatment of endothelial cells revealed the same pattern and antibody specificity as the fluorescence staining. Read More
