Plaques (24) Morphology is variable; lesions may appear annular, ulcerated, hypopigmented, telangiectatic
, diffuse, and psoriasiform.
If the telangiectatic
vessels go on to form a retinal detachment, scleral buckling and drainage of sub-retinal fluid may also be required.
This differs from the telangiectatic
variant of KS in which KS lesions contain large, very congested, ectatic vascular spaces.
The MR and CT appearances may show fluid-fluid levels, which is a nonspecific finding and can be seen in other lesions, including chondroblastoma, giant cell tumor of bone, or telangiectatic
Coats disease is characterised by telangiectatic
retinal vascular abnormalities in association with lipid exudation.
Telangiectasia macularis eruptiva perstans, the rarest form of cutaneous mastocytosis, usually presents as multiple telangiectatic
, reddish brown macules on the trunk in adults (1).
It is the telangiectatic
hemorrhagic pattern that led to the morphologic classification of this tumor as a hemangioma.
9) These patients developed asymptomatic, telangiectatic
yellow-to-white plaques of the sclerae bilaterally.
Radiation colitis also shows hyalinization of the lamina propria, usually with telangiectatic
blood vessels and atypical endothelial cells and fibroblasts.
osteosarcoma shares many similarities with classic ABC, particularly on imaging studies and even on gross morphology.
Various subtypes of osteosarcoma have been described, including conventional, small-cell, parosteal, periosteal, intracortical, intramedullary, giant cell-rich, and telangiectatic
