Human papillomavirus-related multiphenotypic sinonasal carcinoma

Human papillomavirus-related multiphenotypic sinonasal carcinoma (HMSC) is a rare primary tumor of the sinonasal tract that has been reported recently. It is reportedly associated with human papillomavirus infection. The tumor presents with glandular cyst-like histology, but some cases exhibit squamous epithelialization and are positive on p16 immunohistochemical staining. The clinical picture and treatment of this disease have not been established. However, this report describes a recurrent case of this disease treated with salvage surgery. The patient was a 61-year-old woman who presented to the previous doctor with a chief complaint of nasal obstruction. A localized tumor was found in the left nasal cavity and was resected under endoscopic guidance. The postoperative pathological diagnosis was HMSC. Twenty-one months after the surgery, local recurrence was observed, and the patient was referred to our hospital. Since the recurrent lesion had widely infiltrated outside the nasal cavity, extensive resection and reconstructive surgery were performed. Postoperative radiotherapy was performed as an additional treatment. Notably, 13 months have passed since the salvage surgery, and no recurrence has been observed to date.     

Epithelial-myoepithelial carcinoma arising in the nasal cavity

This study documents a case of an epithelial-myoepithelial carcinoma (EMC) in the left nasal cavity. A 70-year-old woman who presented with recurrent epistaxis of the left nasal nostril of 3 months duration was found to have a polypoid tumor in the left nasal cavity. A computed tomography (CT) scan revealed a tumor to occupy the left inferior and middle nasal cavity which had destroyed the inferior nasal turbinate, and a horizontal scan showed the tumor to occupy the middle and posterior nasal cavity. Since the tumor was connected to the lateral wall of the left nasal cavity with a narrow stalk, the tumor was excised by peeling the mucosa from the wall of the left nasal cavity. Based on the histological and immunohistochemical findings, the tumor was diagnosed to be an EMC. The follow-up at 12 months after the operation showed no evidence of recurrence.     

Epithelial-myoepithelial carcinoma of the maxillary sinus: a rare case

Epithelial-myoepithelial carcinoma (EMC) is a rare tumor that commonly involves the salivary glands. EMC of the maxillary sinus is extremely rare. We describe here a case of a 50-year-old patient who presented with right cheek swelling for 7 years and bilateral nasal obstruction and right nasal bleeding for 3 months. A pinkish polypoidal mass was seen in the right nasal cavity. Computed tomography scan revealed an expansile soft tissue mass in the right maxillary sinus with erosion of all of its walls. Histopathological examination of the excised specimen confirmed myoepithelial carcinoma with positive reaction to S-100 and smooth muscle actin. Subsequently, the patient developed regional nodal metastasis in the neck for which neck dissection was performed. Histopathology of the neck dissection specimen revealed metastatic EMC. EMC is rare tumor and a diagnostic dilemma. It should be considered in cases showing dual tumor cell population with clear cell change in histopathology. Common differential diagnosis includes metastatic renal cell carcinoma, acinic cell carcinoma, adenoid cystic carcinoma, mucoepidermoid carcinoma, oncocytoma, and sebaceous carcinoma.

Cancer of the nasal cavity: survival and factors influencing prognosis

OBJECTIVE: To determine overall survival and prognostic factors for cancer of the nasal cavity. DESIGN: Cross-sectional analysis of a national cancer database. METHODS: All cases of nasal cavity cancer were extracted from the Surveillance, Epidemiology and End Results database for 1988 through 1998. Cases with distant metastatic disease were excluded. Tumor histologic types, TNM staging, and pathological features were computed. Kaplan-Meier and Cox proportional hazards analyses were conducted to determine factors influencing overall survival. RESULTS: A total of 981 cases were identified, with 3.5% presenting with distant metastatic disease. After exclusion of missing variables, 783 cases were analyzed, with a mean patient age of 63.8 years. Squamous cell carcinoma was the most common tumor histologic type (49.3%), followed by esthesioneuroblastoma (13.2%). More than half of the cases presented with early (T1) primary site disease, and only 5% had positive nodal disease at presentation. Overall mean (median) survival was 76 (81) months, with an overall 5-year survival rate of 56.7%. On multivariate analysis, male sex, increasing age, T stage, N stage, and poorer tumor grade independently adversely affected survival (P<.05). Radiotherapy was administered in 50.5% of patients and also independently predicted poorer survival (P =.03). The mean (median) survival for squamous cell carcinoma was 79 (84) months; only melanoma showed a statistically significantly poorer mean survival of 40 (30) months when compared with other tumors (P<.001). CONCLUSIONS: Age, sex, and staging variables have a significant prognostic impact in nasal cavity cancer. Melanomas of the nasal cavity manifest very poor survival.     

Human papillomavirus-related multiphenotypic sinonasal carcinoma: A report of two patients and review of the literature

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC) is a recently described sinonasal tract tumor that is associated with high-risk HPV subtype infection. Despite histological features that are suggestive of a high-grade malignant tumor, the prognosis of HMSC is relatively good; however, the clinical features of this tumor are poorly understood. Here, we describe two patients with HMSC. The first was initially diagnosed with adenoid cystic carcinoma of the right nasal cavity; the tumor was extirpated via endoscopic endonasal surgery. Seventy-four months later, the tumor recurred in the right inferior turbinate and was diagnosed as HMSC after biopsy, whereupon it was resected en block via endoscopic endonasal surgery. No adjuvant therapy was administered during either episode; moreover, no recurrences have occurred during the 44 months since the second operation. The second patient was diagnosed with HMSC based on the biopsy of the tumor occupying the left nasal cavity. The tumor was completely resected under endoscopic endonasal surgery, and no adjuvant therapy was administered. There has been no recurrence for 15 months after the operation. Herein, we also review the clinical features of this tumor type based on 69 previously reported cases as well as our patients.

Solitary fibrous tumor in the maxillary sinus treated by endoscopic medial maxillectomy

Solitary fibrous tumor (SFT) is an uncommon neoplasm that usually arises from the pleura. Recently, SFTs have been reported in the head and neck area. SFTs of the nasal cavity and paranasal sinuses are extremely rare, with only 24 cases reported in the English literature. We describe an SFT that arose from the left maxillary sinus and extended to the nasal cavity. The tumor was removed by endoscopic medial maxillectomy, which permitted monobloc excision of the lesion. The patient is without the evidence of the disease 12 months after surgery.     

Identifizierung eines Nasenrachenkarzinoms mit Hilfe der EBV-Diagnostik

We report the case of a 36-year-old women who was found to have a malignant tumor extending from the side of her right nasal cavity to the nasopharynx. Magnetic resonance imaging and computed tomography were not able to define the primary site of the tumor. Histologic evaluation demonstrated an undifferentiated squamous cell carcinoma. Because of the different treatment concepts for carcinomas of the nasal cavity and nasopharynx, we tried to identify the primary site by diagnosing Epstein-Barr virus (EBV) infection, which is associated with carcinoma of the nasopharynx. By using immunohistochemistry and polymerase chain reaction EBV could be identified in the cells of the carcinoma. This showed that the primary site of the tumor was located in the nasopharynx and resulted in the patient being treated with simultaneous radiochemotherapy.

Microcytic carcinoma of the nose cavity. A case report

Tumors of the nasal cavity and sinuses are rather infrequent, being squamous carcinoma the predominant type, which accounts for the 80 percent of the totality of them. Maxillary sinus is the most affected, followed by nose cavity. Half of cases are originated on turbinates. We present the clinical case of a woman patient diagnosed of microcytic carcinoma of the right nasal cavity originated at the level of middle turbinate. The mass filled the width of the fossa getting in touch with the nasal septum, without encroaching it. According its extent the tumor was classified as T2, N0, M0 and treated with radiotherapy only. Microcytic carcinoma is an exceptional histological type in nasal cavity and next to its numeric meagerness in this location makes this case a very peculiar one.     

Epithelial-myoepithelial carcinoma of the nasal cavity

A 22-year-old male presented with a 1-year history of nasal obstruction due to a polypoid mass in the right nasal cavity. Histopathologic examination revealed the tumor to consist of a mixture of a trabecular structure with a double-layered arrangement of inner dark cells and outer clear cells. Immunohistochemical examination showed the clear cells to be positive for α-smooth muscle actin and S-100 protein. Ultrastructural examination confirmed the myoepithelial cell origin. The tumor was excised and no recurrence or metastasis was found 40 months after surgery. We describe here a rare case of epithelial-myoepithelial carcinoma arising from the nasal cavity, one of the most unusual locations. Received: 2 September 1999 / Accepted: 22 February 2000     

Verrucous carcinoma of the nasal cavity: a case report

We report a rare case of verrucous carcinoma occurring in the nasal cavity. A 53-year-old man reporting left-sided nasal obstruction and awareness of a left intranasal lesion--a whitish polypoid lesion--was found in CT to have an expansive lesion of the left nasal cavity and maxillary sinus. The tumor was completely removed by Denker's operation. Verrucous carcinoma is a rare variant of squamous cell carcinoma most commonly seen in the oral cavity. In some cases, conventional squamous cell carcinoma components may be observed focally in verrucous carcinoma, called a hybrid tumor. In our case, the tumor showed typical features of a hybrid tumor. To the best of our knowledge, this is the first case of hybrid verrucous squamous cell carcinoma originating in the nose in the Japanese literature.     

Sarcomatoid carcinoma in the sinonasal cavity: A retrospective case series from a single institution

ObjectivesSarcomatoid carcinoma (SC) is rare in the sinonasal cavity with poor prognosis. This study aimed to summarize the clinical characteristics, treatment and prognosis of patients with sinonasal SC from a single tertiary medical center.MethodsRetrospective review of the clinical data of seven patients diagnosed with sinonasal SC from May 1988 to February 2021.ResultsSeven patients with SC in nasal cavity and paranasal sinus, including six males and one female, aged 34-77 years (mean, 58.3 years), were included in this case series. The common presenting symptoms included epistaxis and nasal obstruction. The tumor usually occurred in nasal cavity, maxillary sinus and ethmoid sinus. Most patients were diagnosed at advanced stages with the involvement of orbit and skull base. Open and endoscopic surgery were performed in five and two patients, respectively. The follow-up period ranged from 3 to 26 months. Four patients died of disease within one year, though two received adjuvant chemotherapy and one received radiotherapy. Two patients survived without recurrence at the end of follow-up, both of them underwent adjuvant radiotherapy. One patient received palliative re-irradiation due to local recurrence of the tumor three months after the surgery, however, this patient was lost to follow-up.ConclusionsSinonasal SC is a rare entity with an aggressive behavior and poor prognosis. Early diagnosis and multimodality treatment are recommended to improve the survival.     

Primary mucosal desmoplastic melanoma of the nasal vestibule: the second case

Primary mucosal desmoplastic melanoma is an exceedingly rare, potentially devastating disease that is often initially misdiagnosed because of its deceptively benign presentation. We report what we believe is only the second case of mucosal desmoplastic melanoma arising from the nasal vestibule. The patient, a 62-year-old woman, presented with an obstructive, enlarging mass in the nasal cavity. The tumor, which was initially believed to be benign, was excised, but it recurred 12 months postoperatively. The recurrence was excised, but 4 years later, the patient experienced a second recurrence; in this case, the tumor had invaded the cribriform plate and extended to the anterior cranial fossa. The tumor subsequently metastasized to the dura mater, which led to the patient's death. We review the distinction between conventional mucosal melanoma and mucosal desmoplastic melanoma, and we discuss the ways in which the behavior of a desmoplastic melanoma can point to the diagnosis. Because a diagnosis can be difficult to establish, we stress the importance of maintaining a high index of suspicion when evaluating pathologic and immunohistochemical findings in a patient with a recurrent mucosal nasal mass.     

Endoscopic removal of esthesioneuroblastoma

Esthesioneuroblastoma is a rare tumor of neural crest origin that arises in the nasal cavity. There is still no consensus on the optimal treatment for this neoplasm, and the literature contains very few accounts of endoscopic excision in these cases. We described a case report of 12-year-old girl with esthesioneuroblastoma that was confined to the nasal cavity and paranasal sinuses, with no orbital or intracranial extension. The tumor was removed via intranasal endoscopic approach and radiotherapy was administered postoperatively. The patient is currently being followed, and there has been no recurrence in 24 months after surgery.

A Clinicopathological Study of Sinonasal Neuroendocrine Carcinoma and Sinonasal Undifferentiated Carcinoma

Objective Sinonasal undifferentiated carcinoma (SNUC) and sinonasal neuroendocrine carcinoma (SNEC) are relatively newly recognized, rare entities requiring further clinicopathological analysis to advance our understanding and determine prognostic distinctions between them. Study Design Retrospective chart review. Methods Cases were retrieved from the Copath system. One patient was seen in consultation from an outside institution. Histological and immunohistochemical findings, patient demographics, treatment regimens, and outcomes were analyzed and compared. Results Ten patients (7 men, 3 women) ranging in age from 17 to 58 years (mean age, 44.7 y) were included. Four patients were classified with SNEC, six as having SNUC. The predominant site was the superior nasal cavity or ethmoids (seven cases), followed by the maxilla (four cases). Disease in four patients was clinically staged as N1 (three with SNUC, one with SNEC), and in six patients as N0 (three with SNEC, three with SNUC). Of the nine patients who were treated initially with surgical resection, seven received postoperative radiation therapy alone, one received postoperative radiation and chemotherapy, and one had only limited postoperative chemotherapy. One patient was treated with radiation therapy and chemotherapy alone, without surgical resection. Follow‐up was obtained ranging from 6 to 108 months (mean period, 26.4 mo). Three patients died of disease 10, 14, and 41 months, respectively, after diagnosis. Three patients had persistent disease at 6, 9, and 21 months, respectively, two of them with distant metastases. Four patients were disease free after 6, 18, 31, and 108 months, respectively. Conclusions SNUC and SNEC are both aggressive tumors, usually presenting in middle age as a nasal mass. Both tumors have the capacity to metastasize locally and distantly, and both can result in poor outcomes. This small series precludes a demographic or prognostic distinction between the two groups.
