introduction: plasmacytoma is a monoclonal proliferation of plasma cells. it can be an isolated lesion, for which the term extramedullary plasmacytoma is used, or a representation of multiple myeloma.the upper respiratory tract is the most common site for an extramedullary plasmacytoma. sinonasal plasmacytomas cause different symptoms depending on the sites of origins and the areas of involveme...

Invasive plasmacytoma appearing as a mass in the paranasal sinuses developed in two patients after cardiac transplantation. Radiographic findings included a sinus mass with bony invasion and expansion. The findings were radiographically indistinguishable from common malignant neoplasms and aggressive infectious processes. Malignant plasmacytoma should be considered in the differential diagnosis...

PURPOSE OF REVIEW New developments in the nasal and paranasal sinus cancers are reviewed. RECENT FINDINGS In addition to woodworking, several risk factors for nasal and paranasal sinus cancers have been identified, most notably smoking. Progress in the differential diagnosis of small round cell nasal and paranasal sinus cancers allows the precise diagnosis of esthesioneuroblastoma. Despite re...

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...

Neuroendocrine neoplasms are defined as epithelial neoplasms with predominant neuroendocrine differentiation. They can arise in almost every organ of the body although they are most commonly found in the gastrointestinal tract and respiratory system. Nasal cavity and paranasal sinuses are a rare site for neuroendocrine carcinoma. In contrast to the other regions, neuroendocrine tumours of the s...

introduction frontal sinus mucoceles are the commonest among all paranasal mucoceles. with introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. case presentation we described a lateral frontal sinus mucocele wit...

Context The effect on survival of orbital evisceration on patients with paranasal sinus neoplasms has not been well established. Objective To review systematically the available literature concerning survival in patients who undergo surgery for paranasal sinus neoplasm with and without preservation of the eye. Data Source A retrospective meta-analysis of English and non-English articles using M...

INTRODUCTION Osteomas are slow- growing, benign tumors. They are the most common neoplasms of the paranasal sinuses. They are usually originates from the frontal and ethmoid sinus and much less frequently seen in the maxillary and sphenoid sinuses. Although the lamina papyracea is a part of ethmoid bone, a giant osteoma originated from the lamina papyracea is very uncommon. An osteoma of the pa...

Endoscopic sinus surgery is a standard procedure in the treatment of various pathologies such as chronic sinusitis or some types of neoplasms. The transnasal approach to tumours of paranasal sinuses is favourable due to functional and aesthetic reasons. We report a rare case of a large primary ectopic meningioma of the paranasal sinuses in a 48-year-old woman referred to the Otolaryngology Clin...
