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 osteosarcoma.
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.
Telangiectatic 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 sarcomas.
