Chronic rhinosinusitis with nasal polyps is a common disease with still unclear pathophysiologic mechanisms. The airway epithelial barrier has been shown to be involved in different chronic disorders, including rhinitis, nasal polyposis and asthma. High mobility group box 1 (HMGB1), a primarily nuclear protein, is involved in the induction of airway inflammation in patients with chronic rhinosi...
The presence of eosinophils was compared in nasal biopsy and smear. Thirty-two nonallergic rhinitis patients, of whom six had nasal polyps, were included in the study. The specimens were studied light-microscopically after staining with hematoxylin-eosin. The association between the presence of polyps and the finding of eosinophils in the biopsy specimens proved to be significant. Ten normal su...
Nasal polyps are usually associated with inflammation, allergy or mucoviscidosis. The global burden of patients COVID-19 infection, including that in the Indian sub-continent,is still very high and they at an increased risk developing invasive fungal infections probably due to their immunocompromised state. Here, we review 4 cases nasal polyposis ongoing past history infection without co-morbid...
Background Inflammation in the nasal mucosa has been shown to correlate with the development of CRSwNP (chronic rhinosinusitis with nasal polyps). The mechanism behind this is not fully understood but changes in the activity of the immune system might contribute to the growth of polyps. The present study focuses on the potential role of MHC II (major histocompatibility complex class II). These ...
The authors report a case of paraganglioma of the skull base presenting as nasal polyps. A 29-year-old patient presented with epistaxis and was found to have nasal polyps. The patient underwent a nasal polypectomy. After pathology showed an unusual appearance, the mass was subsequently excised endoscopically using radiofrequency coblation, and it was found to be originating from the skull base....
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. c...
