Historically, the HA-I subtype was referred to as
telangiectatic focal nodular hyperplasia and was thought to belong to the FNH family.
17) The most frequently reported cytogenetic abnormalities include 1p11-13, 1q21-22, 11p14-15, 14p11-13, 15p11-13, and 19q13, and +1, -10, and -17 (18); however, cytogenetic differences among the various histologic subtypes (conventional,
telangiectatic, smallcell, giant cell, parosteal, and others) have not been systematically explored.
Grade 1 (Low Grade) Low-grade central osteosarcoma Parosteal osteosarcoma Adamantinoma Grade 2 Periosteal osteosarcoma Grade 3 (High Grade) Ewing sarcoma/PNET Conventional osteosarcoma
Telangiectatic osteosarcoma Mesenchymal chondrosarcoma Small cell osteosarcoma Secondary osteosarcoma High-grade surface osteosarcoma Dedifferentiated chondrosarcoma Dedifferentiated chordoma Malignant giant cell tumor
It has also been shown that FFA findings which may be evaluated as perifoveal vascular leakage and lead to unnecessary injections in clinical practice are due to
telangiectatic vessels in the deep vascular layer.
1) The category of cutaneous mastocytosis also includes diffuse cutaneous mastocytosis (characterized by generalized erythema and thickened skin), solitary mastocytoma (present as a solitary brown or red lesion), and telangiectasia macularis eruptiva perstans (diffuse
telangiectatic macules on the skin, usually in adult patients).
Deep inflammatory nodules, enlargement of the
telangiectatic vasculature, dilation of pores on the face, and hyperplasisa of the sebaceous glands and nasal tissue
Spider naevi or spider angiomas are small raised lesions with a central pulsatile punctum and radiating
telangiectatic vessels frequently present over the area drained by the superior vena cava.
Malignant lesions exhibit fast growth (often less than one year of evolution) and adhere to deep layers, with an ulcerated or
telangiectatic surface.
Telangiectatic osteosarcoma: a clinical pathological study of 41 patients at Rizzoli Institute.
Moreover, the vessels in that area appeared
telangiectatic and thin walled, with intimal hyperplasia (Figure 4).
Telangiectatic osteosarcoma, giant cell-rich osteosarcoma, and fibroblastic osteosarcoma should be included in differential considerations when aggressive giant cell tumor of bone is suspected, as these subtypes of osteosarcoma do not produce osteoid matrix [5].
