We present a case of odontogenic maxillary sinusitis whose sinonasal symptomatology was thought to be the consequence of a previous midfacial trauma. The patient was admitted to the Clinic of Oral and Maxillofacial Surgery after more than 10 years of exacerbations of sinonasal symptoms, which began to plague soon after a facial contusion. We decided to perform CT of paranasal sinuses, and despi...
Sinonasal hemangiomas, although rare, must be considered in the evaluation of intranasal masses with profuse epistaxis. Although the availability of literature discussing cavernous hemangiomas in this location is limited, there have been no case reports of exclusively soft tissue sinonasal cavernous hemangiomas extending to the anterior skull base (ASB) that were resected purely endoscopically....
Invasive fungal infections of the sinonasal tract are a rare but known entity in immunocompromised patients. Paecilomyces lilacinus is a nematophagous fungi with septate hyphae that has afflicted humans in multiple forms, causing cutaneous, ocular, and sinonasal infections. Only 4 cases of P lilacinus and 2 cases of Paecilomyces variotii in the sinonasal tract have been reported in the literatu...
Background & objective: Hemangiopericytoma is an uncommon vascular tumor derived from the pericytes of Zimmermann. . The most common location of the tumor is pelvic retroperitoneum and musculoskeletal system of the lower extremities. It is rarely seen in the head and neck area. In addition, only 0.8% to 3% of all orbital tumors and less than 5 % of primary sinonasal tumors are primary hemangiop...
INTRODUCTION Modern advances in endonasal endoscopic surgery have expanded its utility in the management of malignant sinonasal tumours, and the degree to which cases are eligible. Knowledge of the indications, inclusion and exclusion criteria and imaging workup that empowers judicious patient selection is essential. This article discusses the endoscopic resection of malignant sinonasal tumours...
BACKGROUND Sinonasal teratocarcinosarcoma is a rare and aggressive malignancy with histological features of both carcinosarcoma and teratoma. The optimal management of this malignancy is unclear, with most patients being managed by a combination of surgery and radiotherapy. CASE PRESENTATION We describe an 83-year-old white woman with sinonasal teratocarcinosarcoma of her left nasal cavity tr...
Glomangiopericytoma/sinonasal type hemangiopericytoma is a rare sinonasal neoplasm arising from the pericytes surrounding capillaries and accounts for less than 0.5% of all sinonasal tumors. This tumor differs from conventional soft tissue hemangiopericytoma in location, biologic behaviour and histologic features. Glomangiopericytoma is a borderline low malignancy tumor with a good prognosis af...
Sinonasal tumors often mimick inflammatory diseases. If misdiagnosed, results are life threatening. This article comprises of study done on 5 patients who presented with nasal mass. They underwent clinical examination, diagnostic endoscopy, radiology and histopathological examination (HPE). Thorough evaluation helps the surgeon diagnose rare cases thus preventing detrimental outcomes. Herein we...
Sinonasal squamous papilloma is a benign epithelial tumor having variable squamous differentiation. It occurs in the nasal cavity and paranasal sinuses. Malignant transformation of sinonasal squamous papilloma is responsible for cancer-related deaths worldwide. We reported a 52-year old man diagnosed as malignant transformation of a large sinonasal squamous cell papilloma. Moreover, bilateral n...
Sinonasal region is an exceptional site for metastatic tumors. Renal cell carcinoma is known to metastasise to the most unusual sites, the sinonasal region being one of them. Clear cell carcinoma is its most common histologic variant. A sixty year old male presented with epistaxis and nasal obstruction. Clinical examination and CT scan revealed a vascular tumor in the right nasal cavity and max...
