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. Isolated intraorbital mucocele without paranasal sinus disease is a rare condition. We present a 39-year-old female patient with right medial canthal swelling without any nasal symptoms, and normal nasoendoscopic finding. Imaging revealed the lesion as a right ethmoidal mucocele with normal paranasal sinuses. However intraoperatively, it was an isolated intraorbital lesion, lateral to lamina papyracea with thick-yellowish mucin discharge.

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. Although NF is only rarely diagnosed in children, the head and neck represent the most common locations for NF among this population. The cause of NF remains unknown, however trauma is believed to be an important triggering factor. We describe an unusual case of NF in the posterior ethmoid sinus in a six-year-old boy with no history of trauma. The NF was incidentally noted on a computed tomography scan after the patient complained of a squint. The diagnosis of NF was also supported by histopathology and specific immunohistological staining. A surgical biopsy was performed, and no recurrence was observed after one year.

Osteomas of paranasal sinuses are slow-growing benign tumour, which is often asymptomatic. The prevalence is highest amongst fourth and sixth decades. Paranasal sinus osteomas are most commonly found in the frontal sinus. Osteomas are usually asymptomatic and found incidentally on radiographic examination. The symptoms depend on its size and location. Common symptoms include frontal pain, nasal discharge, posterior nasal drip, bump over the inner aspect of the lower eyelid and epiphora. We described a case of 34-year-old woman with an enlarging right medial canthal swelling for 10 years, with increased intercanthal distance followed by persistent right nasal blockage. Because of worsening symptoms, she had sought for treatment in which endoscopic approach excision was performed.

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, aggressive benign bony tumour that has been distinguished from a larger group of ossifying fibromas (OF) based on age of occurrence, most common site of involvement, and its clinical behaviour.We reported a case of asymptomatic 14 year old boy who had incidental finding of left ethmoidal bony mass on his CT brain imaging done for post traumatic cerebral concussion. The diagnosis of juvenile psammomatoid ossifying fibroma (JPOF) was made based on radiological and histological findings.International Journal of Human and Health Sciences Vol. 02 No. 04 October’18.
