OBJECTIVES: To analyze the clinicopathological features and the CT and MRI features of patients with paranasal sinus fibrosarcoma. METHODS: Seven patients with surgically and pathologically confirmed paranasal sinus fibrosarcoma were enrolled. Their CT and MRI data and imaging features were retrospectively analyzed in detail. RESULTS: The study participants were two males and five females (median age, 43 years; range, 22-73 years). CT or MRI imaging showed a well-defined (n = 5) or ill-defined (n = 2), irregular (n = 6) or oval (n = 1) mass, with heterogeneous (n = 7) density...

BACKGROUND: With the exception of osteomas, bone neoplasms that originate in the sinonasal cavity are seldom diagnosed on preoperative imaging due to a lack of characteristic radiographic features. Here we described the unusual occurrence of an osteoblastoma in the paranasal sinuses, and we drew focus to its salient imaging features. A highly unique imaging sign was indicated, and its pathologic basis was explained, with concurrent review of the literature. METHODS: Case series and review of the literature...

INTRODUCTION: Ewing sarcoma (ES) of the sinonasal tract and associated primitive neuroectodermal tumors are rare. To our knowledge, only 10 case reports of sinonasal ES of the nose or paranasal sinuses have been reported. Furthermore, there has been only 1 case of sinonasal ES arising from the middle turbinate. Recommended management of sinonasal ES stems from the management of its osseous counterpart, ES, but treatment with surgery, radiotherapy, and chemotherapy is varied. Five-year survival rates vary from 21% to 70%, with the lower rates representing patients presenting with metastatic disease...

Non-Hodgkin's lymphoma (NHL) is a lymphatic system tumor originating from either B or T lymphocytes and shows a high malignant potential. In HIV-seropositive patients, NHL of head and neck is mainly found in Waldeyer's ring, oral mucosa, salivary glands, paranasal sinuses, and laryngeal tissue. Primary NHL rarely affects the bone. When the lesion affects the bones of the jaws, it is rare in the mandible when compared to the maxilla. In the reported cases, only 0.6% are found in the mandible. NHL of the mandible can be difficult to diagnose, and so the prime aim of the present case report is to establish appropriate diagnosis of one of such kinds...

Avian influenza A(H7N9) virus infections frequently lead to acute respiratory distress syndrome and death in humans. We aimed to investigate whether primary cultures of human respiratory tract epithelial cells are helpful to understand H7N9 virus pathogenesis and tissue tropism, and to evaluate how patient-related characteristics can affect the host's response to infection. Normal human bronchial epithelial cells (isolated from two different donors) and primary epithelial cells (harvested from 27 patients undergoing airway surgery) were experimentally infected with H7N9 and/or H1N1pdm for 72 h...

INTRODUCTION: Biphenotypic sinonasal sarcoma (BSNS) is a recently described mesenchymal tumor exclusive to the sinonasal region. It is a low grade sarcoma, displaying evidence of myogenic and neural differentiation. Role of β-catenin immunohistochemistry in distinguishing it from its morphological mimics is not well-established. We conducted this study to identify cases of BSNS from our archives, and to examine immunopositivity for β-catenin in them as well as in its close differential diagnosis...

Head and neck squamous cell carcinomas (HNSCC) are a diverse group of tumor types, including neoplasia of the paranasal sinuses, oral cavity, trachea, pharynx and larynx. Laryngeal cancer is the most common type of HNSCC. The proline-rich 4 (PRR4) protein is synthesized in the acinar cells of human lacrimal glands. Previous studies have demonstrated that PRR4 may function as an antimicrobial protein protecting the ocular surface and the oral cavity. In order to determine differentially expressed genes (DEGs) in laryngeal tumors, a GeneFishing Assay was performed; 27 DEGs were identified...

Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017...

Introduction: Inverted papilloma is a locally-aggressive benign neoplasm of the paranasal sinuses with a high potential for recurrence and malignancy. Intracranial extension is infrequent, and dural penetration even more so, typically associated with recurrence of the disease or its degeneration into squamous cell carcinoma. Clinical Case: A 32-year-old female patient consulted us for an exophytic lesion in her right nostril and exophthalmos, associated with headache, anosmia and dysgeusia...

Hemangiopericytomas (HPCs) are uncommon vascular tumors originating from extracapillary cells called pericytes, and rarely occur in the nose or paranasal sinuses. We treated a 57-year-old man with nasal HPC who presented with nasal obstruction and hemorrhage. Nasal endoscopy showed a readily bleeding mass between the right nasal septum and inferior turbinate. Enhanced CT revealed a heterogeneous mass lesion with an enhancement effect that filled the right nasal cavity. A biopsy specimen was proved to exhibit a HPC histopathology...

A schwannoma is a benign tumor arising from Schwann cells present in the nerve sheath of myelinated nerves.It is rarely seen in the nose and paranasal sinuses, and it very rarely originates from the nasal septum. A 40-year-old female presented to our outpatient department with a gradual onset, progressive, left nasal obstruction since the last 4 years. On performing a local examination, a soft tissue mass occupying the left nasal cavity was seen. Surgery via the external approach was performed; the mass was found to arise from the nasal septum and was totally excised...

Background: Osteosarcomas of head and neck region have unique biology and exhibit a clinical behavior and natural history that is distinct from osteosarcomas of the trunk and extremities. Our understanding of this malignant bone tumor is largely based on data from single institutions or compiled from registries, and hence the clinical practice guidelines seem confusing and conflicting. Aims and Objectives: To analyze the demographic profile, disease characteristics and survival outcomes of osteosarcoma of head and neck region...
