Angiofibromas are rare vascular tumors which originate predominantly in the nasopharynx and occur typically in male adolescents. Extranasopharyngeal sites such as nasal cavity and paranasal sinuses are less frequent. This review article was undertaken to evaluate the incidence, clinical features and management of extranasopharyngeal angiofibromas originating exclusivelly from nasal cavity structures. Our focus of interest was to evaluate the significance of immunohistochemical analysis in diagnosis of such extremely rare neoplasms. In the PubMed and Google Search, we found only 39 cases of nasal angifibroma, 27 males and 12 females from 1980 to 2012. The most prevalent site of origin was nasal septum, followed by inferior and middle turbinate. The commonest symptoms were nasal obstruction and epistaxis. Nasal angiofibromas are clinically distinct from nasopharyneal angiofibromas and can therefore be misdiagnosed. The differential diagnosis includes other vascular lesions, such as lobular capillary hemangioma and sinonasal-type hemangiopericytoma. Although immunohistochemistry is not necessary for differentiation between angiofibroma and capillary hemangioma, that diagnostic procedure may be helpful in distinction from sinonasal hemangiopericytoma. As an ilustration for immunohistochemical analysis, we presented a case of an elderly woman with tumor arising from the middle turbinate, diagnosed as angiofibroma. The staining was positive for CD34, CD31, factor VIII, vimentin and smooth muscle alpha-actin, and negative for desmin. and A. Perić, J. Sotirović, S. Cerović, L. Zivić
Autoři prezentují případ intramuskulárně lokalizovaného hemangiomu v podpaží u tříletého dítěte s náhle vzniklou poruchou hybnosti levé horní končetiny. Předmětem diskuse je přínos zobrazovacích metod v odlišení od jiných měkko tkáňových lézí, zejména sarkomů. Hlavním cílem práce je upozornit na podobnost různých měkkotkáňových lézí v zobrazovacích metodách a nezbytnost histologického vyšetření ke stanovení správné diagnózy., The authors present a case of intramuscular hemangioma localized in the armpit of a three-years old child with sudden onset movement disorders left upper extremity. The discussion is the contribution of imaging in the differentiation from other soft tissue lesions, particularly sarcomas. The main goal is to draw attention to the similarity of different soft tissue lesions in imaging methods and the need for histological examination to establish the correct diagnosis., Červinková I, Skotáková J, Pavlovský Z., and Literatura
Oncocytic Schneiderian papilloma (OSP) is one of the three morphologically distinct tumors that arise from Schneiderian membrane (the others include exophytic papilloma and inverted papilloma). OSP almost always occurs unilaterally in the paranasal sinuses, usually in the maxillary sinus, ethmoid cells or sphenoid sinus. We report a case of a 64-year-old woman with OSP arising from the left frontal sinus. In the report herein, we describe an OSP originating in the region of frontal sinus, which, to the best of our knowledge, represents the first documented example in English literature of OSP developing in this anatomical site. and D.

Uvedena kazuistika pětiletého chlapce s týden trvajícími bolestmi a výtokem z pravého ucha. Obtíže přetrvávaly i přes nasazenou antibiotickou léčbu. Otoskopický nález odpovídal polypózní mase obturující zevní zvukovod se sanguinolentní sekrecí. Chlapci bylo provedeno vyšetření hlavy počítačovou tomografií s vysokým rozlišením (HRCT) a magnetickou rezonancí (MR) s nálezem měkkotkáňové masy, vyplňující zevní zvukovod, středoušní dutinu a pneumatický systém mastoidního výběžku a s rozsáhlou destrukcí skeletu v oblasti mesotympana, protympana, hrotu pyramidy a stěny karotického kanálu vpravo. Konečnou diagnózu rhabdomyosarkomu stanovilo histologické vyšetření vzorku odebraného z polypózní masy ze zevního zvukovodu. Cílem sdělení je upozornit na možnost málo časté, ale závažné příčiny sekrece z ucha., We report a case of 5-year-old boy with a week lasting pain and a discharge of the right ear. Symptoms persisted without improvement despite antibiotic treatment. The otoscopic finding seemed to be a polyp mass obturing an external auditory canal and was accompained with a sanguinolent discharge. The boy's head was examined by high resolution computer tomography (HRCT) and magnetic resonance imaging (MRI) with finding of soft tissue mass filling the external auditory canal, a middle ear, mastoid and its air cell system and large bone destruction in the area of the mesotympanum, protympa-num, apex of pyramid and carotic canal on the right side. The final diagnosis of rhabdomyosarcoma was set down by histological examination of a sample obtained from polyp mass in external auditory canal. The aim of this article is to call attention to a possibility of rare but serious cause of the ear discharge., Dědková J., Chrobok V., Bělobrádek Z., and Literatura
