Xiong et al. reported the largest series of primary non-Hodgkin’s lymphoma (NHL) of the nasal cavity [8]. Median age of presentation was 44 years (Range: 11-79 years) and males were affected more often than females. Maxillary sinus was the most frequent site of involvement followed by the ethmoid sinus and the nasopharynx. The most common presenting symptoms include nasal obstruction, epistaxis...

Cemento-ossifying fibromas are benign lesions of the jaw, which arise from the periodontal membrane. Histopathologically these are composed of fibrous tissues with calcified structures resembling bone and cementum. Surgical resection is the treatment of choice. They have rarely been reported in the ethmoid sinus, maxillary sinus and sphenoid sinus Mastoid bone is an extremely rare site of such ...

Oncogenic osteomalacia (OO) is an uncommon but treatable cause of osteomalacia related to tumor production of FGF23, usually caused by benign mesenchymal neoplasms. Paranasal sinus glomangiomas are a rare cause of OO, with only one previously reported case. Here we describe a second case (first reported in English) of paranasal sinus glomangioma-induced osteomalacia in a 42-year-old man. He pre...

Mucoceles are benign tumors of the sinuses, caused by obstruction sinus ostium. They most often affect frontal and ethmoid sinuses.The clinical representation mucoceles is changeable according to their sizes, extensions, nature affected sinus. The diagnosis a mucocele based on computed tomography (CT) or even better magnetic resonance imaging. Despite nature, they can be responsible for serious...

We report a case of extensive paranasal sinus and orbit rhabdomyosarcoma (RMS) with intra-cranial invasion treated successfully with chemotherapy and radiotherapy. A 13-years-old male patient complained of painless and progressive proptosis of his left eye for two weeks. Ocular examination showed elevated intraocular pressure, limited extraocular movement, proptosis, and conjunctival ciliary in...

OBJECTIVES/HYPOTHESIS To assess relevant variations in the anatomical course of the infraorbital nerve (ION). This understanding may reduce the risk of surgical injury. METHODS A total of 100 consecutive computed-tomography sinus studies obtained in a tertiary referral center were reviewed, and measurements were made of the 200 IONs. Anatomic variants were classified into three types based on...

Abstract Background Frontal sinus carcinoma is commonly seen as an extension of the ethmoid sinus, overlying skin, or lacrimal gland. The existence this disease has been unclear. We aimed to describe occurrence primary frontal carcinoma. Methods conducted a systematic literature review and retrospective medical records at our institution in past 10 years. Results Sixty-four articles were includ...

Cemento-ossifying fibromas are a group of rarely occurring benign tumours, developing from the periodontal membrane and varying considerably in appearance and in the progress of the disease. Their common feature is higher or lower production of cemental tissue. In most cases the tumours are small because their cementoma mature quickly and become inactive, which causes the tumour to stop growing...
