Inflammatory or allergic sinonasal polyps are characterized by extensive growth of blood vessels and ectasia with pseudoamyloid precipitation in 5% of cases. Angiomatous nasal polyps (ANP) is a relatively rare benign lesion, which may be misdiagnosed as benign or malignant tumors. ANP characteristic pathological features expanded angiogenesis, extracellular accumulation of amorphous eosinophilic substance and atypical stromal cells.
This report aims to outline the ANP histological diagnosis. Through a full histopathological examination, we studied biopsies and resected specimens from five patients diagnosed with ANPS, including one with facial deformities. Gross findings demonstrate that tumors firm in consistency, lobulated surface, and lined by mucous membrane partially ulcerated. light microscopy showed the group widened, thin-walled blood vessels between eosinophilic substance congo red-negative with extensive necrosis and irregular spindle cell stroma.
The presence of myofibroblasts endothelial cells was confirmed by electron microscopy and immunohistochemistry. This is a report of four cases showed an extreme example ANPS really resected with endoscopic sinus surgery for all patients. Full histopathological examination is recommended to confirm the possible differential diagnosis for a better management plan
Clinical and Pathological Features of Angiomatous Nasal Polyps: A Report of Four Cases and Review of Literature.
We searched Medline from 1946 to 2019 for reports exploring differences between PNES and other comparable paroxysmal events using clinical instruments, few of which focused on the differential diagnosis using broad-based questionnaires covering multiple aspects of this condition. The majority investigated single items to highlight specific differences, either qualitative or quantitative, between groups and to elucidate some of the pathogenetic mechanisms of PNES.
We selected all variables that proved to be useful for differentiating PNES from other types of paroxysmal events and classified them by category, by instrument utilized and method of investigation. This body of data will constitute the basis for assembling a new set of evidence-based questionnaires for patients and eyewitnesses to facilitate the differential diagnosis of these disorders, especially in resource-poor clinical settings.
This will require a skillful translation of the content of each selected variable into clear and intuitive questions, appropriate for lay responders. Predictive variables found by more than one investigator, especially if using different approaches, have greater diagnostic weight and should be prominent in future questionnaires. However, even variables so far found to be predictive by one investigator will deserve consideration. Once the preliminary text of the questionnaires is consolidated, the instrument will need extensive testing and validation in large prospective studies before becoming available for clinical use in its definitive format.

Description: Alpha-tubulin Antibody: Alpha-tubulin belongs to the tubulin superfamily, which is composed of six distinct families. Along with beta-tubulins, alpha-tubulins are the major components of microtubules. These microtubules are involved in a wide variety of cellular activities ranging from mitosis and transport events to cell movement and the maintenance of cell shape. Alpha- and beta-tubulin dimers are assembled to 13 protofilaments that form a microtubule of 22-nm diameter. Tyrosine ligase adds a C-terminal tyrosine to monomeric alpha-tubulin. Assembled microtubules can again be detyrosinated by a cytoskeleton-associated carboxypeptidase. Another post-translational modification of detyrosinated alpha-tubulin is C-terminal polyglutamylation, which is characteristic of microtubules in neuronal cells and the mitotic spindle. Like GAPDH and beta-Actin, this antibody makes an excellent loading control in immunoblots.
