Vascular Mimicry Expression in Invasive Ductal Carcinoma; A New Technique for Prospect of Aggressiveness
Background & Objective: In vascular (vasculogenic) mimicry (VM), tumoral cells mimic the endothelial cells and form the extracellular matrix-rich tubular networks. It has been proposed that VM is more extensive in aggressive tumors. This study was designed to investigate the rate of VM expression in the stromal cells of invasive ductal carcinoma (IDC) and to find its relationsh...
متن کاملA novel imaging technique for experimental choroidal neovascularization.
PURPOSE Choroidal neovascularization (CNV) is the end point of several ocular diseases that lead to blindness. The authors developed an imaging technique for visualizing and quantifying morphologic changes associated with experimental laser-induced CNV. METHODS CNV was induced using laser energy to disrupt Bruch's membrane. Rats were euthanatized immediately after laser injury and at 1, 2, 3,...
متن کاملEx-PRESS shunt for choroidal fluid drainage in uveal effusion syndrome type 2: a potentially novel technique.
Uveal effusion syndrome (UES) was reported by Schepens and Brockhurst in 1963,1 and later described as a nanophthalmic disorderwith a scleral abnormality.2 Gass3 described idiopathicUES and hypothesized that the causewas a congenital anomalyof the sclera and vortex veins that was related to aging, hormonal changes, or impairment of the permeabilityof the sclera.Using histologicalmethods,Trelsta...
متن کاملTechnique for Robotic Stereotactic Irradiation of Choroidal Melanoma.
Radiotherapy has a long history in the organ-sparing management of choroidal melanoma. Joining plaque radiotherapy and proton irradiation, stereotactic robotic photon irradiation is a new tool in the radiation oncologist's armamentarium for ocular tumors. The non-coplanar fields with steep dose gradients are well suited to spare uninvolved retina, anterior chamber, and the optic nerve. In our p...
متن کاملMinimally invasive technique for curettage of chondroblastoma using endoscopic technique.
Chondroblastoma is a rare benign bone tumor. The treatment for chondroblastoma usually consists of curettage of the lesion and packing the tumor cavity with bone grafts or bone cement. However, chondroblastomas are known to recur in 10% to 20% of cases after excision, possibly because the incomplete removal of pathological tissue at surgery. We present a case of chondroblastoma in the distal fe...
