Diagnostic value of serum and tissue eosinophil in diagnosis of asthma among patients with chronic rhinosinusitis.

Background: Chronic rhinosinusitis (CRS) is one of the most common chronic inflammatory diseases of sinonasal mucosa. Asthma among CRS patients is often underdiagnosed which makes the management of CRS more challenging. Therefore, using serum and tissue eosinophil as an indicator and predictor of asthma in CRS patients is vital for further preventing recurrent and increasing the effectiveness of treatment for CRS.

Pseudotumor of the Infratemporal Fossa Complicated with Orbital Apex Syndromes.

Background: The infratemporal fossa poses a great challenge to surgeons due to its complex anatomy and communications to many surrounding areas. The disorders that arise from this area can be infections and neoplasms. They can cause varieties of complications due to the extension of the pathologies and compression effect to the other adjacent structures.

Posterior Ethmoid Nodular Fasciitis.

Nodular fasciitis (NF) is an uncommon and benign tumour-like fibroblastic proliferation that is difficult to distinguish from sarcoma both clinically and histologically. In addition, it is a type of lesion characterised by having a potential for spontaneous regression. NF is frequently misdiagnosed due to its rapid growth, rich cellularity, and mitotic figure.

A Rare Intraorbital Mass: An Isolated Mucocele.

Mucocele is a mucous filled benign cystic lesion. It develops due to obstruction of any natural os-tium of the paranasal sinus. Even though being benign, it has capability to erode and cause thinning the adjacent bony structures.
