Lymphoepithelial carcinoma of the nasal cavity mimicking juvenile angiofibroma

Juvenile angiofibroma, nasopharyngeal carcinoma (NPC) and lymphoepithelial carcinoma of the nasal cavity (LEC NC) all could be found as a hyper-vascular mass in the nasopharynx area. Performing biopsy for histopathologic confirmation is necessary in the case of NPC or LEC NC but could be fatal in the case of angiofibroma. In our case, a 21-year-old male who was suffering from unilateral nasal stuffiness and frequent epistaxis had a mass with an easily bleeding tendency in his right nasal cavity. Juvenile angiofibroma was suspected by clinical and radiologic examinations. We performed preoperative angiography and the feeding vessel from the right internal maxillary artery was obliterated with polyvinyl alcohol nanoparticle. The mass was completely removed endoscopically, and there was profound hemorrhage in spite of the preoperative embolization. The mass turned out to be LEC NC by postoperative histopathologic examination. To avoid this misdiagnosis, the authors suggest that we should perform biopsy under rigid endoscopy 24h after angiographic embolization. If the result of frozen biopsy is juvenile angiofibroma, we could perform surgery another 24h later. If the result is nasopharyngeal carcinoma or LEC NC, we could avoid unnecessary surgical removal and perform radiotherapy. In terms of treatment strategies, we suggest endoscopic removal of gross tumor and postoperative combination of chemoradiotherapy as the more curative regimen with less complications related with radiotherapy.     

Cholesteatoma of the nose and maxillary and ethmoid sinuses: a rare complication of palatal surgery

A 10-year-old boy presented with a complaint of a left-sided nasal obstruction with an associated foul-smelling discharge. Physical examination and anterior rhinoscopy revealed that a whitish, friable mass had completely filled the left nasal cavity. On computed tomography, a soft-tissue mass was seen filling the cavity and extending to the paranasal sinuses with bone erosion. A biopsy of the mass suggested that it represented a cholesteatoma. The lesion was removed via nasal endoscopy, and histopathology confirmed the diagnosis of a cholesteatoma. No recurrence was noted during 6 months of follow-up. Cholesteatoma of the paranasal sinuses is a rare entity, as only a few dozen cases have been reported in the literature.     

Vasomotor rhinitis following trauma to the nose

Complaints of nasal obstruction following nasal trauma without any deformation have been noticed by rhinologists for many years. However, neither an epidemiologic nor a pathophysiologic connection has ever been established. The complaints and physical examination findings of these patients resemble those of vasomotor rhinitis. Only very few articles suggesting nasal trauma as a possible cause for vasomotor rhinitis have ever been published. We present a retrospective study that found 87 of 802 patients to suffer from vasomotor rhinitis following nasal trauma. No other factors known to cause vasomotor rhinitis were present in these patients. None had any previous nasal problems. We therefore suggest that nasal trauma was the causative factor in their vasomotor rhinitis.     

Nasal cavity ossifying fibrosarcoma: an unusual fibro-osseous neoplasm

We describe the case of a 65-year-old woman who presented with left nasal obstruction. Clinical and radiographic examinations revealed the presence of a soft-tissue mass that had obliterated the left nasal cavity. The mass was completely excised via an endoscopic approach. Histopathologic examination identified the tumor as an ossifying fibrosarcoma. The patient recovered uneventfully and remained free of disease at the 2-year postoperative follow-up. To the best of our knowledge, no case of an ossifying fibrosarcoma of the nasal cavity has been previously reported in the English-language literature. We discuss the features of this case and the clinical presentation, diagnosis, and management of fibrosarcomas of the nasal cavity and paranasal sinuses.     

Surgery of the nasal columella in external valve collapse

The authors describe and discuss their experience with the collapse of the external nasal valve, focusing on the role that surgery of the columella plays in solving this problem. Thirty-seven cases were treated. In all but I there had been a previous septorhinoplasty. Seven patients had concomitant internal valve collapse. A modified alarplasty associated with columelloplasty was adopted in the cases with severe collapse. When the reduction of the nostril opening was mild to moderate, the surgical strategy varied depending on the width of the columella base: alarplasty in cases with a narrow to normal columella, and columelloplasty in the presence of a wide columella base. The authors' philosophy tends to minimize intervention on the nasal valve areas. Their results demonstrate that when the collapse and its functional effect are not too severe, a good result can be achieved by working only on the columella, especially if its base is significantly wide.     

Paraganglioma of the skull base presenting as nasal polyps

The authors report a case of paraganglioma of the skull base presenting as nasal polyps. A 29‐year‐old patient presented with epistaxis and was found to have nasal polyps. The patient underwent a nasal polypectomy. After pathology showed an unusual appearance, the mass was subsequently excised endoscopically using radiofrequency coblation, and it was found to be originating from the skull base. The diagnosis was made using a combination of clinical findings, radiology, and histopathology examination. It is important to consider paraganglioma in the differential diagnosis of unusual tumors of the nose and skull base. Laryngoscope, 2013     

The rare case of nasal glioma

The authors presented a case of nasal glioma in an adult man which had performed as nasal polyp. Histopathologic studies confirmed neuroglial tissue--Astrocytoma fibrillare. These tumor cells were immunohistochemically positive for glial fibrillary acidic protein as well as for S-100 protein and vimentin. There was no communication between the tumor and the cranial cavity on radiological examination (TC, MRI). Treatment is usually surgical. In this article authors describe a case of a nasal glioma that was removed via a lateral rhinotomy.     

Basaloid Squamous Cell Carcinoma in Nasal Cavity

Basaloid squamous cell carcinoma (BSCC) is often founded in the head and neck region. However, BSCC in the sinonasal tract is rare. We report here on the case of a 58-yr-old woman who presented with nasal obstruction and epistaxis. Computed tomography and examination of the nasal cavity revealed a tumor mass that originated from the right inferior turbinate with erosion of the nasal floor. The tumor that was attached to the inferior turbinate, the lateral nasal wall and the eroded right side hard palate, and so all this was resected. Histopathologic examination of the excised tumor confirmed BSCC in the nasal cavity. We report here on a nasal cavity BSCC that was treated with partial maxillectomy only.     

Fibrous dysplasia of right upper jawuncommon presentation

MR, 30 years, M/M had huge nasal mass for 25 years and nasal obstruction for 15 years. On examination, a huge mass involving right side of face, nose, cheek, orbit and palate of 10″ × 8″ size was noticed. The right eye was proptosed eccentrically and was completely blind. Histopathological examination diagnosed the case to be fibrous dysplasia.     

Nasal cavity paraganglioma with malignant transformation: a case report

BACKGROUND: In this report, we describe a young woman with a nasal cavity paraganglioma with malignant transformation. METHODS AND RESULTS: A 23-year-old woman presented with frequent right-sided epistaxis. Physical examination revealed a pedunculated mass originating from the right superior turbinate and filling the posterior nasal cavity. The endoscopically removed mass was composed of a reddish anterior portion and a white, flesh-looking posterior portion, the latter comprising the majority of the tumor. Histologically, the anterior portion showed a paraganglioma and the posterior portion showed a separate malignant lesion simulating Ewing's sarcoma/PNET. She underwent wide endoscopic excision including the site of tumor origin and has been followed up for 3 years without any evidence of disease recurrence. CONCLUSION: This is a rare case of nasal cavity paraganglioma that had transformed into a malignant tumor.     

Coexistence of benign schwannoma and lymphoma in a nasal polyp

The existence of a combined benign schwannoma and lymphoma presenting as a nasal polyp has not been described in the English literature. We are reporting this rare combination in a 50-year-old male whose presenting symptoms were nasal obstruction, nasal deformity and headache. Examination of the left nasal cavity revealed a mass which was confined to the nose on computed tomography (CT) scan examination. Histopathology of the mass revealed a major component to be a benign schwannoma and a minor component a large B-cell lymphoma.

Malignant oncocytoma of the nasal cavity: a case report.

Malignant oncocytoma is a rare clinical entity and is most commonly seen in the salivary glands. Its occurrence in the nasal cavity is extremely rare, and only 4 such cases have been reported in the literature. The authors report one such case in a 60-year-old woman, which presented as a slow-growing nasal mass arising from the nasal septum, with no lymph node metastasis, which was successfully managed by a combined modality of treatment-surgery followed by radiation therapy. The relevant literature has been reviewed. The case is discussed as a possible differential diagnosis for a mass in the nose.     

Post-transplant lymphoproliferative disorder presenting as epistaxis

An unusual case of epistaxis resulting from post-transplant lymphoproliferative disorder is described. A 30-year-old woman who had undergone renal transplantation 12 years previously presented with profuse, posterior, unilateral epistaxis. The initial findings, workup and treatment are presented. A post-nasal space (PNS) mass was detected and biopsy showed this to be an Epstein-Barr virus-positive polymorphous B-cell post-transplant lymphoproliferative disorder. Computed tomography findings showed a polypoid lesion protruding from the sphenoethmoidal recess and filling the left PNS. Post-transplant lymphoproliferative disorder is well known to involve tonsil tissue. Commonly, this is the first presentation of the disease in children. However, until now post-transplant lymphoproliferative disorder has not been described in the PNS or nasal cavity presenting as epistaxis. We conclude that all transplant patients presenting with epistaxis should be followed up for an accurate examination of the PNS and nasal cavity after the acute episode.     

Atypical presentations of rhinosporidiosis: a clinical dilemma?

Rhinosporidiosis is a chronic inflammatory disease common in India and Sri Lanka. Its manifestations are mostly nasal, though extranasal ones in head and neck region are not rare. Occasionally these presentations lead to diagnostic dilemma. Here we present some cases with its associated confusions if any. In this study thirty five patients were included. Extranasal manifestations were noted in nine cases. Two patients attended with laryngopharyngeal and one with lacrimal sac presentation-subsequent nasal endoscopic examination revealed presence of nasal masses, too. Other six cases presented with polypoidal mass hanging from nasopharynx into oropharynx. One of them was confused with nasopharyngeal angiofibroma. Two laryngopharyngeal masses were removed successfully with rigid laryngoscope followed by cauterisation of the base. The solitary lacrimal sac mass was excised by external approach combined with nasal endoscope guided excision of nasal mass. The other six cases with nasopharyngeal attachment were subjected to nasal endoscope guided removal. In all these cases, the base of the lesions was cauterised. The experience about the various manifestations and diagnostic problems is discussed here.     

Nasal angiomyolipoma

Angiomyolipomas (AMLs) are hamartomatous lesions containing smooth muscle, vasculature and mature adipose tissue. AML occurs most frequently in the kidneys, with the liver being the second commonest site of involvement. Other localizations for AML are extremely rare and, to our knowledge, only six cases of AML of the nasal cavity have been reported to date. Our case involved a 52-year-old male who presented with a history of snoring and obstruction of the left nasal cavity. Physical examination revealed a 3-cm polypoid mass in the left nasal cavity, which was excised surgically. Histopathologic examination revealed that the lesion was composed of smooth muscle bundles, mature adipose tissue and blood vessels of different sizes. No epitheloid smooth muscle cells were observed and HMB-45 staining was negative. In conclusion, although nasal AML is a rare lesion, it should be considered in the differential diagnosis of polypoid nasal masses, especially when the mass occurs unilaterally.

Cervical chordoma in childhood: clinical statistical contribution

Parapharyngeal neoplasias are rarely noticed in childhood, since they have their peak incidence between the 2nd and 4th decade of life. The authors report a case of a 4-year-old patient presenting with a retrostyloid mass, accompanied by nasal obstruction and some difficulty in swallowing at 12 months of age. CT scanning well ascertained the delimitation of the tumor, but it was of no help in the differential diagnosis. In fact, after surgical excision, the histological examination of the specimen revealed a chordoma. This result was unexpected because of the region concerned and the lack of a CT demonstration of the cervical boney involvement. A cervical vertebral localization of a chordoma is rare in all age groups and it is of particular clinical and statistical interest in infancy.     

Angiomatous ethmoidochoanal polyp in an infant: case report

Nasal polyps are rare in children younger than 10 years. We describe the case of an infant girl who had undergone a traumatic intubation at birth that had resulted in nasal bleeding. At the age of 5 months, she was brought to us with an obstructive left nasal mass. Imaging revealed the presence of an ethmoidochoanal polyp, as well as a fracture of the posterior cribriform plate and a small associated meningocele. Four months later, the polyp was excised, and the meningocele was corrected with endoscopic nasal surgery. Pathologic evaluation identified the lesion as an angiomatous polyp, which was probably related to the previous traumatic episode. We discuss the clinical aspects of a pathologic entity that has not been previously reported in an infant.
