Introduction  Appearance of nasal masses on routine CT and MRI are not pathognomonic. We utilized the apparent diffusion coefficient (ADC) value obtained from diffusion weighted image (DWI) to detect the differences in the microstructures of tumor and non-tumor tissues. Objective  The objective of our study was to evaluate the diagnostic role of DWI and ADC values in differentiating between malignant and benign sinonasal lesions and its correlation with histopathological results as the reference standard...

Perioperative complications after transsphenoidal surgery for pituitary adenomas have been well documented in the literature; however, some complications can occur in a delayed fashion postoperatively and reports are sparse about their occurrence, management, and outcome. Here, we describe delayed complications after transsphenoidal surgery and discuss the incidence, temporality from the surgery, and management of these complications based on the findings of studies that reported delayed postoperative epistaxis, delayed postoperative cavernous carotid pseudoaneurysm formation and rupture, vasospasm, delayed symptomatic hyponatremia (DSH), hypopituitarism, hydrocephalus, and sinonasal complications...

BACKGROUND: Sellar pathology is increasingly addressed using the expanded endonasal approach (EEA). Although avascular graft reconstruction is an acceptable means to prevent cerebrospinal fluid leak, there are few data regarding sinonasal morbidity in these patients. In this study we compare rates of persistent postoperative crusting (PPC) and rhinosinusitis in patients undergoing sellar reconstruction with mucosal autografting and acellular dermal allografting (ADA). METHODS: Patients undergoing the EEA between 2008 and 2014 were categorized into 2 subgroups: mucosal reconstruction and ADA reconstruction...

Meningioma is a neoplasm of the meninges, which usually occurs in intracranial sites. Extracranial meningioma has been frequently reported in the sinonasal tract and skull bone, often as extension of intracranial meningiomas. Isolated heterotopic meningioma without contiguous intracranial lesion is extremely rare. A 56-year-old woman presented in December 2015 with 2 firm subcutaneous scalp masses; one in the left lateral (temporal) and the other in the left superior (parietal) region. The clinical impression was that of lipoma...

Secretory carcinoma (SC) is a recently described salivary gland carcinoma with characteristic ETV6-NTRK3 fusion. In this case report, we described a SC of the maxillary sinus that underwent high grade transformation in a 61-year-old patient. The diagnosis was confirmed by the presence of ETV6 translocation. Within the sinonasal tract, SC is an important differential diagnosis especially of sinonasal adenocarcinoma, non-intestinal type (non-ITAC), as these two entities bears histologic and immunophenotypic similarity...

BACKGROUND: Tumors occurring in the sinonasal area are characterized by unfavorable outcome due to difficult diagnosis, treatment, and prognosis of the disease corresponding with the anatomic complexity of the area. METHODS: We used quantitative real-time polymerase chain reaction (PCR) to compare relative expression of miR-21, miR-141, and miR-200c in 70 formalin-fixed, paraffin-embedded samples of sinonasal carcinoma tissue (majority of squamous cell carcinoma [SCC] samples) with 17 control samples of sinonasal tissue...

Although schwannomas are commonly found in the head and neck region, their presence in the sinonasal tract involvement is extremely rare, estimated as less than 4%. The presence of these lesions in the frontal sinus are even less common. We report two patients with schwannomas originating in the frontal sinus, with variable degrees of extension. These patients underwent resection of the tumors via an endoscopic or combined approach. The histological diagnosis confirmed schwannoma. Though these lesions have traditionally been approached through larger craniotomies and open procedures, these cases represent less invasive approaches for these rare frontal sinus schwannomas, and demonstrate them as a valid alternative with minimal morbidity for the patient...

NUT midline carcinomas (NMCs) are rare, poorly differentiated tumors with aggressive biological behavior and a characteristic molecular signature. Availability of NUT antibody has facilitated diagnosis of NMC without molecular testing. We report a series of head and neck NMCs diagnosed using NUT IHC at our institute, including one case with an unusual course. Immunohistochemistry for NUT was performed in nasal and sinonasal tumors with diagnoses of undifferentiated carcinoma, poorly differentiated squamous cell carcinoma and malignant neoplasm, not otherwise specified, to identify cases of NMC...

The diffuse neuroendocrine system continues to be an enigmatic topic of study in pathology due to its controversial embryologic origins, biology and a variety of tumors engendered. Originally thought to be localized to the classic neuroendocrine organs (pituitary, thyroid, pancreas and adrenal medulla), the neuroendocrine cells are now known to be distributed in every organ system of the body. A number of human diseases have been linked to aberrations in the functioning of the neuroendocrine cells. Neoplasms of the neuroendocrine system can thus occur in myriad primary sites and range in behavior from benign to lethal...

BACKGROUND: Tumors invading both the anterior skull base and the sinonasal area have been traditionally accessed via largely invasive open craniofacial approaches. Minimally invasive extended endoscopic endonasal approaches have recently become increasingly available, but have anatomical limitations and require incremental experience and thus high patient volume. Our objective was to assess the applicability of a novel combination of the minimally invasive supraciliary incision and the limited maxillofacial osteotomy as a combined surgical approach for large tumors invading both the anterior skull base and the sinonasal area...

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC), originally known as HPV-related carcinoma with adenoid cystic carcinoma-like features, is a peculiar neoplasm that is restricted to the sinonasal tract, exhibits features of both a surface-derived and salivary gland carcinoma (particularly adenoid cystic carcinoma), and is associated with high-risk HPV. Given the limited number of published cases, the full clinicopathologic spectrum of this neoplasm is unclear. Here, we present an updated experience of 49 cases...

Solitary fibrous tumors (SFTs) of the head and neck are uncommon. Lesions previously diagnosed in the head and neck as hemangiopericytomas (HPCs), giant cell angiofibromas (GCAs), and orbital fibrous histiocytomas (OFHs) are now recognized as within the expanded spectrum of SFTs. To better understand the clinicopathologic profile of head and neck SFTs, we performed a multi-institutional study of 88 examples. There was no sex predilection (F:M ratio 1.2), and the median patient age was 52 years (range: 15 to above 89 y)...

Sinonasal tract (SNT) alveolar rhabdomyosarcoma (ARMS) are frequently misdiagnosed, especially in adults. Fifty-two adult (≥18 years) patients with SNT ARMS were reviewed and characterized by immunohistochemistry and molecular studies. Twenty-six females and 26 males (18-72 years; mean 43.2 years), presented after a short duration (mean 2.6 months) with a large (mean 5.5 cm) destructive nasal cavity mass, involving multiple contiguous paranasal sites (n = 46) and with cervical adenopathy (n = 41)...

Primary sinonasal melanoma is a rare disease. We present a case of melanoma in sinuses without abnormal F-FDG activity anywhere in the scanned portion of the body. In further assessment, C-choline PET/CT revealed high activity in the paranasal sinuses, skull base, and adjacent brain, in agreement with the high signal on contrast-enhanced T1-weighted MRI scan, which suggested the residual tumor.

Sinonasal undifferentiated carcinoma (SNUC) is a rare malignancy of the upper airways and anterior skull base that carries a poor prognosis. The tumor is known to be invasive into the surrounding structures of the skull base and brain. To date, there is only one existing case report documenting drop metastasis to the intradural extramedullary spinal cord. To the best of our knowledge, we present the second case of metastatic SNUC to the spine. This report describes a 59-year-old male with a history of head and neck SNUC who presented with thoracic back pain and bilateral lower extremity paresis...

OBJECTIVES: Improvement in sinonasal quality of life (QoL) following sinus surgery has been well-documented across the literature. To our knowledge, only one series has evaluated long-term QoL in patients undergoing tumor resection, and that study demonstrated no improvement in rhinologic QoL following malignant tumor resection at 2-year follow-up. The objective of the present study was to evaluate QoL in the 2 years following endoscopic malignant tumor resection. METHODS: A prospective cohort study was performed, including patients with both malignant and benign sinonasal tumors in a tertiary academic medical center...

Lacrimal sac tumors are extremely rare but can be life threatening. Seventy percent of lacrimal sac tumors are of epithelial origin. Inverted transitional cell papilloma of the lacrimal sac is a rare epithelial sinonasal tumor of benign etiology with local invasion and malignant potential. These lesions may remain undiagnosed or may present with signs and symptoms of dacryocystitis or may transform to transitional cell carcinomas. Most lesions are diagnosed intra-operatively while performing a dacryocystorhinostomy...

BACKGROUND: The nasoseptal flap (NSF) is a universally used surgical technique to cover defects of the skull base after extended sinonasal surgery. Long-term follow-up of complications, sequelae, and smell function is largely unknown. OBJECTIVE: The main objective of this study was to investigate monorhinal olfaction after transsphenoidal skull base surgery. METHODS: Patients who underwent skull base surgery for midline lesions (craniopharyngioma and pituitary tumors) by using a NSF, also referred to as the Haddad flap, were assessed for their long-term outcome...

INTRODUCTION: Sinonasal squamous cell carcinoma (SCC) accounts for <1% of all malignancies but represents 70% of sinonasal cancer. Up to 10% of SCCs are associated with inverted papilloma (IPSCC). Studies that compare patients, treatment, and outcomes of SCC and IPSCC are absent in the literature. METHODS: A retrospective review of patients with SCC and those with IPSCC at Cleveland Clinic and Indiana University from 1995 to 2015. The records were analyzed for demographics, tumor characteristics, treatment, and outcomes...
