Solitary extramedullary plasmacytoma of the rhinopharynx

Solitary extramedullary plasmacytoma involving the nasopharynx is very rare. A case of asymptomatic extramedullary plasmacytoma in the nasopharynx in a 69-year-old man is presented. Radiotherapy was the treatment (60 Gy). In this patient two neoplasms of B series are associated (lymphoproliferative B Kappa syndrome and extramedullary plasmacytoma).     

Solitary fibrous tumor of the paranasal sinuses

Although solitary fibrous tumors are well-recognized in the pleura, their occurrence in the paranasal sinuses is decidedly uncommon. We have encountered two cases of solitary fibrous tumors in the paranasal sinuses and report the clinicopathological findings including CD34 immunoreactivity. One tumor arose in a 55-year-old Japanese businessman and the other in a 53-year-old man who had been in the hospital for schizophrenia for 20 years. The tumors showed characteristic findings. Immunoperoxidase stains on paraffin sections showed staining of the cells for anti-vimentin, but there was no staining for anti-keratin, anti-S-100 protein, anti-desmin, anti-glial fibrillary acidic protein (GFAP), or anti-actin. Anti-CD34 monoclonal antibodies also reacted with these tumors, as those of the pleura generally do, and were found to be useful in diagnosing these tumors.

Solitary extramedullary plasmacytoma of the maxillary sinus. Case report

Solitary extramedullary plasmacytomas are rare tumors that often affect head and neck region. Because of the non-specific associated symptomatology, they frequently are misdiagnosed. We briefly describe a 69-year-old woman who developed solitary plasmacytoma in the left maxillary sinus and was initially treated as having sinusitis. We also report the diagnostic work-up that is necessary to establish a correct diagnosis in such cases. This case highlights that an appropriate investigation for neoplastic disease should be performed in patients presenting with persistent symptoms that resemble those of sinusitis, especially if these do not resolve after conservative medical treatment.     

Solitary plasmacytoma of bone and soft tissues

PURPOSE: To define the optimal treatment and outcomes for patients with solitary plasmacytoma of bone and soft tissue. METHODS: Review of the literature. RESULTS: Solitary plasmacytomas are uncommon and account for less than 5% of plasma cell neoplasms. Solitary plasmacytomas of bone (SPB) usually occur in the vertebra and skull and are more common than extramedullary plasmacytomas (EMP) that almost always arise in the head and neck and may spread to regional lymph nodes. The optimal treatment is moderate-dose radiotherapy (40-50 Gy) and occasionally surgery. Adjuvant chemotherapy does not improve survival. Patients with EMP have a relatively low risk of progressing to multiple myeloma and have improved survival compared with those who present with SPB. CONCLUSION: Solitary plasmacytoma is an uncommon neoplasm that often arises in the head and neck. Optimal treatment is moderate-dose radiotherapy. Prognosis is relatively good and is better for patients with EMP compared with those presenting with SPB.     

Solitary fibrous tumor of the nasal cavity, paranasal sinuses and anterior fossa

Solitary fibrous is rare mesenchymal neoplasm that usually arises in the pleura or less commonly is related to other serosal surfaces. There were reported SFTs in some extrapleural locations. There locations cause diagnostic difficulties. Ethmoid sinuses, nasal cavity and anterior fossa are rare site for SFTs. Authors report a case of SFT of the nasal cavity, paranasal sinuses and anterior fossa in 33 year-old woman to show the difficulty and importance of recognition. Diagnostic procedures and medical treatment are presented. This report pays attention that SFT should be taken into consideration during diagnostic process of spindle-cell lesions of the nasal cavity and paranasal sinuses in order to avoid some confusions.     

Pneumatization of the paranasal sinuses (maxillary and frontal) in cleft lip and palate

A comparative study of roentgenograms of the paranasal sinuses between 37 patients with cleft lip and palate and 37 control subjects of the same age group was done using a planimeter. The results indicate that there is no statistical difference in the sizes. The paranasal sinuses increased in size with age in patients as well as in control subjects.     

Single extramedullary plasmacytoma of the nose

A new solitary extramedullary plasmacytoma of nasal localization meeting the conditions for definition is reported. The patient was treated with surgery and irradiation, which controlled the disease and produced excellent cosmetic results. The bibliography is reviewed and the pathologic, clinical, and evolutive characteristics are discussed.     

Sarcoidosis of the paranasal sinuses

European Archives of Oto-Rhino-Laryngology - Sarcoidosis is a chronic disease, which predominantly affects the lung. Since sinonasal sarcoidosis is rare, little is known about the sarcoidosis...     

Tumors of the paranasal sinuses

Benign and malignant tumors, including polyps, represent conditions that occur frequently enough to be considered in the differential diagnosis of sinus disease. The locations and extent of these lesions (especially malignant tumors) should be evaluated by CT and MRI. This is especially indicated when malignant lesions extend outside the confines of the paranasal sinuses into adjacent areas, such as the orbit, intracranial cavity, and parapharnygeal space.     

Sarcoidosis of the paranasal sinuses

The authors described diagnostics difficulties, clinical features and treatment of this disease. The treatment is insufficient, but only interventional, although the clinically dominating symptoms may be due to a chronic disease inside of the sinuses and they are known to be caused by specific disorders in immunology. Immunosuppression, using prednisone, and reestablishing sinus ventilation and drainage via natural ostia is the basis of treatment, but it does not lead to recovery. Two rare cases of paranasal sinuses sarcoidosis are described.     

Exostoses of the paranasal sinuses

While bony exostoses of the external auditory canal have long been recognized as a complication of cold-water swimming, bony exostoses of the paranasal sinuses have not been previously reported. We present an unusual case of multiple exostoses of the paranasal sinuses, which began coincident with nasal irrigation with cold gentamicin solution. The patient had had prior endoscopic sinus surgery. Topical antibiotic gentamicin irrigation lessened recurrence of bacterial sinus episodes. He admitted to using the irrigation directly from the refrigerator daily for two years. A biopsy was consistent with exostosis. Patients should be counseled to avoid irrigating their paranasal sinuses with cold irrigants. Laryngoscope, 2010.     

Solitary malignant schwannoma of the nasal cavity and paranasal sinuses: report of two rare cases

Malignant schwannomas of the paranasal sinuses are extremely uncommon tumors, as only 18 well-documented cases have been previously published in the English-language literature. We report two new cases of solitary malignant schwannoma--one in a 23-year-old man and the other in a 45-year-old woman. Neither was associated with von Recklinghausen's disease. These tumors involved the maxillary sinus, nasal cavity, and orbit and extended intracranially. Following surgery, both patients experienced recurrences. The male patient developed a slowly enlarging intranasal mass at the same site 8 years following excision of the original tumor and postoperative radiotherapy. Microscopic examination of the recurrent tumor revealed that its features were similar histologically to those of the original. The female patient experienced a recurrence 1 year following her first operation.     

Meningoencephalocele of the paranasal sinuses

Meningoencephaloceles are not commonly seen by the otolaryngologist. They occur most frequently in the lumbosacral area where they are five times as common as in the occipital area. The anterior cranial presentation is quite rare. Most patients with meningoencephaloceles present early with large lesions and are treated by the neurosurgeon. Two patients are presented who had small meningoencephaloceles which were located in the paranasal sinuses and successfully treated by an extracranial approach. This approach is recommended for those lesions of the paranasal sinus where the resulting bony defect from the removal of the lesion is small and the sinus is not infected.     

Neurofibromas of the paranasal sinuses

Two cases of neurofibroma of the paranasal sinuses are presented. The tumours presented as space-occupying lesions and were treated by local excision. Histologically one was a typical neurofibroma, whilst the other showed some features of a schwannoma. The patients show no evidence of tumour recurrence at 18 and 6 months respectively.     

Osteoma of the paranasal sinuses

Osteamas of the paranasal sinuses are rare, They often appear as a coincidental finding on X-ray in patients having radiographs for same other reasons. Tomographic evaluation is the mainstay surgical access and its subsequent follow up. We report a series of 20 cases of osteamas of the paranasal sinuses who underwent surgery for their symptoms. Wide exposure at surgery is necessary for complete or near complete removal. Tumour close to the dura, optic-nerve and internal carotid artery may be left Close and long period offollow-up is essential, especially when the tumour is partially left behind. In our experience, the rate of growth of tumour is very slow and a wait and watch policy can he adopted for very small tumours and those that are incompletely resected.
