“…Three subtypes of this tumor are recognized: exophytic papilloma, oncocytic papilloma, and inverted papilloma [1, 3–5]. The inverted papilloma representing around 4% of all primary sinonasal tumors is the most common type of Schneiderian papilloma and it occurs predominantly in white males with mean age of 50 years [2, 3, 6].…”

Inverted Schneiderian papilloma is an uncommon benign tumor that presents tendency to recur and propensity to be associated with malignancy in approximately 10% of the cases. Some of these lesions are isolated in the maxillary sinus, and predominantly affect white males with mean age of 50 years. We report a case of squamous cell carcinoma arising from inverted Schneiderian papilloma in the maxillary sinus extending to the mouth. The patient was submitted to extraction of a maxillary molar tooth four months before the exacerbation of the symptoms of nasal airway obstruction and facial enlargement. Computed tomography scan revealed a sinonasal mass causing opacification of the right maxillary sinus with destruction of the lateral nasal wall and maxillary sinus floor. The patient was referred to an oncology center for treatment and died from tumor progression one year after the cancer was diagnosed. The intention of this report is to alert dentists to include the inverted Schneiderian papilloma, either associated with squamous cell carcinoma, or not, in the differential diagnosis of maxillary sinus tumors with aggressive behavior, which may extend to the oral cavity or involve roots of teeth.

“…The vast majority of carcinomas arising in SP are squamous cell carcinoma (SCC); however, other types of carcinomas have been described. [6][7][8] We have herein reported a case of a classic exophytic SP, although it is a common topic reported in the otorhinolaryngology literature, to our knowledge, there is only 1 other case of SP reported in the dermatological literature. 8 We think it is important for dermatologists to know about differential diagnoses of lesions on the anterior nasal vestibule.…”

“…Malignant transformation is exceptional with only a few cases reported in the literature, as opposed to inverted and oncocytic types, which have around 27% risk of malignant transformation. The vast majority of carcinomas arising in SP are squamous cell carcinoma (SCC); however, other types of carcinomas have been described …”

A man in his 30s presented with a mass in the right nostril that had been growing for about 1 year. The lesion bled with minimal trauma but did not obstruct his breathing. The patient did not smoke and denied any medical history of chronic rhinosinusitis. Physical examination revealed a 1-cm, nontender, exophytic, verrucous, skin-colored plaque on the right nasal vestibule (Figure , A and B). A diagnostic shave biopsy specimen was taken after informed consent was obtained (Figure , C and D). Clinical image A Clinical image B Histologic image C Histologic image D Figure. A and B, An exophytic, verrucous, and skin-colored plaque on the right nasal vestibule. C, Histologic sections display papillary fronds with slender fibrovascular cores that are lined by nonkeratinizing squamous epithelium (original magnification ×200). D, Higher magnification shows mucin-containing goblet cells. Neither cytologic atypia nor atypical mitotic figures are present (original magnification ×400).

Bilateral Sinonasal Inverted Papilloma: Report of an Uncommon Case Involving Sinuses of the Face and Orbital Cavity

et al. 2021

Patient: Male, 60-year-old Final Diagnosis: Sinonasal inverted papilloma Symptoms: Facial asymmetry • nasal obstruction • right hemiface proptosis Medication: — Clinical Procedure: — Specialty: Dentistry • Pathology • Surgery Objective: Rare disease Background: Nasosinusal papilloma is a benign aggressive tumor. It usually occurs unilaterally in the nasal cavity and can extend to the sinuses. The diagnosis is made by the correlation of findings observed in tomographic and histo-pathological exams. The recommended treatment is surgical excision with clinical monitoring. Orbital involvement occurs in about 9% of cases of advanced SIP. However, there is no report of cases of a benign tumor that invaded the adjacent soft tissues. Therefore, our objective is to report an unusual case of SIP that bilaterally involved the nasal cavity and maxillary sinuses, and extended to involve the ethmoidal cells and sphenoid and frontal sinuses. Case Report: In this article, we report an unusual presentation of sinonasal inverted papilloma (SIP) in a 60-year-old man. The tumor bilaterally involved the nasal cavity and maxillary sinuses and extended to involve the ethmoidal cells and the sphenoid and frontal sinuses, as well as the orbital cavity on the right side. An open surgical procedure was performed for complete removal of the lesion and follow-up with imaging exams. Conclusions: The involvement of these structures is uncommon in SIP. This highlights the importance of this case report. Diagnosis and surgical treatment must be carefully planned. In this work, we describe all the steps that helped guide the choice of the best surgical technique to be performed and offer the best clinical follow-up.
