RATIONALE: Intraductal papillomas of the accessory parotid glands are extremely rare benign tumors that are most commonly derived from minor salivary glands and are easily misdiagnosed as other diseases. Studying these lesions by pathology and immunohistochemistry can raise awareness of the disease, reduce the rate of misdiagnosis, and provide more precise treatments. PATIENT CONCERNS: A 35-year-old man first presented to our hospital with a 6-month history of a painless mass on his left parotid gland...

An inverted papilloma is a benign neoplasm that occurs exclusively in the sinonasal cavity; an inverted papilloma involving the mastoid cavity is extremely rare. We present the case of a patient with an inverted papilloma of the mastoid cavity secondary to cholesteatoma surgery. No case that occurred after acquired cholesteatoma has been reported in literature. A 39-year-old female who was diagnosed with cholesteatoma was treated with a modified radical mastoidectomy in 1988. After recurrence, the patient underwent a canal wall down mastoidectomy in 2006...

Inverted papillomas are tumors of the sinonasal tract with a propensity to recur. Raman spectroscopy can potentially identify inverted papillomas from other tissue based on biochemical signatures. A pilot study comparing Raman spectroscopy to histopathology for 3 types of sinonasal tissue was performed. Spectral data of biopsies from patients with normal sinonasal mucosa, chronic rhinosinusitis, and inverted papillomas are compared to histopathology using principal component analysis and linear discriminant analysis after data preprocessing...

The spectrum of low-grade intraductal papillary proliferations of the salivary glands is heterogenous, and reproducible morphologic diagnostic criteria have not yet been established. Recognized types are sialadenoma papilliferum, inverted ductal papilloma, and intraductal papilloma, but some lesions have been possibly included in the morphologic spectrum of cystadenoma or low-grade intraductal carcinomas. We herein present detailed morphologic, immunophenotypic, and genotypic features of 3 minor salivary gland neoplasms affecting 2 men (aged 65 and 71 y) and 1 woman (aged 78 y)...

Optical coherence tomography (OCT) and confocal laser scanning microscopy (CLSM) are light-based imaging techniques that allow for a visualization of microscopic tissue properties in vivo. Our study was to examine whether they allow for differentiation of inverted papilloma (IP) from nasal polyps (NP). Five cases of IP and NP, respectively, were investigated intraoperatively with OCT and CLSM. Biopsies were taken of the investigated area and were analyzed ex vivo with OCT and CLSM and then underwent HE-staining for standard light microscopy...

OBJECTIVES: On computed tomography (CT), sinonasal schwannoma displays as a soft-tissue mass without any distinctive features. Our aim was to define the radiological criteria for distinguishing schwannoma from other sinonasal benign tumours. METHODS: We retrospectively identified consecutive patients who were pathologically diagnosed with benign sinonasal tumours between 2007 and 2016. CT attenuation values were compared between benign tumours and the brainstem...

OBJECTIVES/HYPOTHESIS: Tenuous evidence has supported the hypothesis that sinonasal inverted papilloma (SNIP) arise from human papillomavirus (HPV) infection. To clarify the role of HPV in SNIP, all known HPV sub-types were evaluated by employing a robust polymerase chain reaction-based method in a wide variety of SNIPs from a single institution. STUDY DESIGN: Retrospective surgical specimen tumor sample analysis. METHODS: HPV positivity among SNIP samples and those with squamous cell carcinoma (SCC) were compared...

BACKGROUND: Sinonasal inverted (schneiderian) papilloma (IP) is histologically benign but shows a propensity for malignant transformation. Survivin, a member of the inhibitor of the apoptosis family of proteins that controls cell division, apoptosis, metastasis, and, probably, also neoangiogenesis, is overexpressed in essentially all human cancers. Overexpression of the multidomain protein cortactin has also been associated with increased cell migration, invasion, and metastatic potential in several malignancies...

OBJECTIVES: High-resolution microendoscopy (HRME) is an optical imaging modality that allows real time imaging of epithelial tissue and structural changes within. We hypothesize that HRME, using proflavine, a contrast agent that preferentially stains cell nuclei and allows detection of cellular morphologic changes, can distinguish sinonasal pathology from uninvolved mucosa, potentially enabling real-time surgical margin differentiation. STUDY DESIGN: Ex vivo imaging of histopathologically confirmed samples of sinonasal pathology and uninvolved, normal sinus epithelium...

BACKGROUND: Inverted papillomas (IPs) are benign neoplasms, most commonly arising from the mucosal lining of the maxillary sinus. IPs can have single or multifocal sites of attachment. Although pedicle location is an important factor to consider in surgical planning, it is less clear whether the location or number of IP attachment sites hold any prognostic value. Herein, we aimed to determine the prognostic significance of the number and location of attachment sites of IPs originating from the maxillary sinus when managed by a pure endoscopic approach...

Inverted papilloma of the prostatic urethra is an especially rare finding. A 75-year-old man with urinary retention wished to proceed with a holmium laser enucleation of the prostate (HoLEP) and was found to have a mass arising from his prostate vs bladder on preoperative imaging. Cystourethroscopy revealed the mass arising from the median lobe of the prostate. After transurethral resection and frozen analysis confirmed the benign pathology of an inverted papilloma, the patient subsequently underwent a successful HoLEP during the same surgical setting...

A 57 year-old, male presented with a chronic unilateral nasal obstruction and epistaxis. Intranasal endoscopy showed multiple polypoid lesions. The computed tomography exam revealed a heterogeneous mass that occupied the right nasal cavity with osteolysis of the middle and lower cone causing fluid retention of the right maxillary sinus. He underwent resection of these lesions. Pathological examination revealed malignant transformation of nasal inverted papilloma into sarcomatoid carcinoma. This case report highlights the importance of considering malignant transformation in the differential diagnosis of polypoid lesions...

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...

RATIONALE: Inverted papilloma (IP) is a benign tumor that should be monitored carefully because it frequently recurs and has the potential to become malignant. PATIENT CONCERNS: We report a case of a 59-year-old woman who presented with a mass which had been found incidentally on positron emission tomography computed tomography (PET CT). DIAGNOSES: Using endoscopy and CT, the preoperative diagnosis was inverted papilloma. PET CT showed a mass with hot uptake in the left ethmoid and frontal sinus (maximum standardized uptake value (SUVmax) = 7...
