Histological findings in bilateral asymmetrical vasoproliferative retinal tumor.
Summary of "Histological findings in bilateral asymmetrical vasoproliferative retinal tumor."
We present a case of a bilateral vasoproliferative tumor of the retina in a young man. The first symptom was visual impairment due to vitreous hemorrhage. The right eye showed small tumors which were successfully treated by repeated cryocoagulation, photocoagulation and bevazicumab injection. The tumor in the left eye was larger and eventually led to a painful secondary glaucoma. After enucleation, this tumor was examined histologically and immunohistochemically. The clinical and histological differential diagnoses and therapeutic options are discussed.

A 50-year-old male patient presented with erectile failure and loss of libido. In the physical examination, there were stone-hard indurations in his bilateral testes. The ultrasonographic study demons...
Purpose:Optical coherence tomography (OCT) is an established diagnostic tool for retinal pathologies in human eyes and was adapted to small animal models. However, there are only few attempts to use O...
Urocortin 2 (Ucn 2) is a corticotrop releasing factor paralog peptide with many physiological functions and it has widespread distribution. There are some data on the cytoprotective effects of Ucn 2,...
Steroid cell tumors of the ovaries are rare sex-hormone secreting tumors which are usually benign and unilateral. One previous study has estimated the tumors to be bilateral in 6% of patients. We repo...
To evaluate the multimodal imaging findings in retinal deep capillary ischemia (DCI).
The inner retina is crucially dependent on an adequate retinal blood supply. When the retina becomes ischemic and hypoxic this results in severe vision loss due to retinal neovascularizati...
Hereditary Haemorrhagic Telangiectasia (HHT, also known as Osler-Weber-Rendu Syndrome) is an disease that leads to the development of dilated and fragile blood vessels. We propose to obtai...
The purpose of the study is to compare Multi-Slice Computer Tomography findings with histological and physiological changes observed in transplanted lungs with Progressive Graft Disfunctio...
Patients with bilateral heterogeneous pulmonary emphysema benefit to differing degrees from unilateral ELVR with complete lobe closure in comparison with incomplete bilateral treatment.
This randomized, single-blind study compares the effectiveness of bilateral training to unilateral training for individuals with moderate hemiparesis. We hypothesize that bilateral traini...
Medical and Biotech [MESH] Definitions
Congenital, often bilateral, retinal abnormality characterized by the arrangement of outer nuclear retinal cells in a palisading or radiating pattern surrounding a central ocular space. This disorder is sometimes hereditary.
An unusual and aggressive tumor of germ-cell origin that reproduces the extraembryonic structures of the early embryo. It is the most common malignant germ cell tumor found in children. It is characterized by a labyrinthine glandular pattern of flat epithelial cells and rounded papillary processes with a central capillary (Schiller-Duval body). The tumor is rarely bilateral. Before the use of combination chemotherapy, the tumor was almost invariably fatal. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1189)
In vivo method of screening investigative anticancer drugs and biologic response modifiers for individual cancer patients. Fresh tumor tissue is implanted under the kidney capsule of immunocompetent mice or rats; gross and histological assessments follow several days after tumor treatment in situ.
A group of rare, idiopathic, congenital retinal vascular anomalies affecting the retinal capillaries. It is characterized by dilation and tortuosity of retinal vessels and formation of multiple aneurysms, with different degrees of leakage and exudates emanating from the blood vessels.
A metalloflavoprotein enzyme involved the metabolism of VITAMIN A, this enzyme catalyzes the oxidation of RETINAL to RETINOIC ACID, using both NAD+ and FAD coenzymes. It also acts on both the 11-trans- and 13-cis-forms of RETINAL.
