Antrochoanal polyps are benign lesions originating from the mucosa of the maxillary sinus. Nasal obstruction and rhinorrhea are their main symptoms. Their endoscopical and radiological appearance makes them relatively easy to diagnose. These polyps are usually presented unilaterally, although bilateral presentation is also possible. We described two cases of atypically giant antrochoanal polyps: in a 15-year-old child and in a 38-year-old man. In both cases, the diagnosis was done by nasal endoscopy and computed tomography (CT) of the paranasal sinuses and supported by histopathological analysis. In the first patient, the excised polyp had the histological characteristic of an angiomatous antrochoanal polyp. Because of their unusual dimension, the combined transoral and endonasal endoscopic approach was performed for complete polyp excision. We discussed the clinical, histopathological and immunohistochemical characteristics of choanal polyps in comparison to inflammatory nasal polyps, and the applicable surgical techniques for treatment of these polyps.

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.

We present a rare case of eosinophilic fungal rhinosinusitis with nasal polyps in a 32-year-old woman caused by basidiomycete fungus Schizophyllum commune. Diagnosis was done by the endoscopic nasal examination, computed tomography (CT) of the paranasal sinuses, the histopathological examination of polyps, the presence of eosinophils and fungal hyphae in nasal mucus and by the detection of S. commune by culture. The patient was successfully treated by combination of oral itraconazole and topical corticosteroid therapy combined with surgery. The pathogenesis and diagnosis of allergic fungal rhinosinusitis are also discussed.

The purpose of this report was to present an unusual case of an unilateral tonsillar hypertophy caused by actinomycosis. It is an infrequent bacterial infection nowadays. Only five such cases have been reported up to now. Diagnosis is difficult, because there are not specific diagnostic procedures. Medical treatment consists of surgical excision of tonsils and postoperative antibiotic therapy.

Partial or total pneumatization of the middle turbinate is called concha bullosa. It's one of the most common anatomic variations of the lateral nasal wall. The exact reason of such pneumatization is not known. It can originate from the frontal recess, middle meatus, sinus lateralis or, less frequently, from the posterior ethmoid cells. Concha bullosa remains usually asymptomatic. However, an extensively pneumatized middle turbinate may constitute space-occupying mass, and thus, it may cause nasal obstruction. We report an extremely rare case of a patient with a large, doubly septated concha bullosa with four different sources of aeration.
