Brown tumor of the maxilla associated with primary hyperparathyroidism

Brown tumors represent the terminal stage of the remodeling processes during primary or secondary hyperparathyroidism. During the last three decades primary hyperparathyroidism has been recognized much more commonly and the increase has generally been attributed to the routine determination of calcium by new automated methods and the advent of new and more objective parathyroid hormone radioimmunoassay techniques. Early diagnosis and successful treatment of the disease have made clinical evidence of bone disease uncommon. While, the mandible is the most frequently involved bone in the head and neck region, maxillary involvement is extremely rare. A case of brown tumor on the maxilla associated with primary hyperparathyroidism is reported. This patient presented multiple skeletal lesions, which are uncommonly seen nowadays. The diagnosis was suggested by the clinical history and confirmed by biochemical, radiological and histopathological determinations. Excision of a parathyroid adenoma normalized the metabolic status. Excision of the maxillary mass led both histopathological confirmation of the disease and early masticator rehabilitation.

BACTERIOLOGY OF CHRONIC SUPPURATIVE OTITIS MEDIA

Aspiration of exudate through an open perforation was performed in 183 patients with chronic otitis media. The pus was cultured aerobically and anaerobically. Aerobes only were isolated from 71 patients (39%); 20 patients (11%) had only anaerobes; and 91 patients (50%) had both aerobes and anaerobes. Only 1 specimen had no growth. There were 259 aerobic isolates. Pseudomonas aeruginosa was recovered from 68 patients. Other aerobes commonly recovered included Staphylococcus aureus and Klebsiella pneumoniae. There were 178 anaerobic isolates. Only anaerobic gram-positive cocci were isolated in 20 instances. Sixty-three Bacteroides isolates were recovered, including 12 Bacteroides fragilis group and 21 Bacteroides melaninogenicus.

Ultrasonography in laryngeal cancers

Endolaryngeal spread of laryngeal malignant tumours is usually determined by conventional endoscopy; however, it can not measure the outward extension of the tumour. As an alternative method for assessing the extension of a tumour and detecting metastatic lymph nodes, we have introduced high-resolution ultrasonography (US) in 34 patients with laryngeal epidermoid carcinoma. The ultrasonographic results were compared with the clinical, operative and histological findings. The ultrasonography revealed malignant extensions in the thyroid cartilage in nine cases, in the carotid artery in four cases, and in the thyroid gland in five cases. These were confirmed by surgical and histopathological examinations. Six patients out of the 34 were subclinical cases, who had metastatic lymph nodes, which were diagnosed by US only. In this study US had a sensitivity of 94.44 per cent and a specificity of 93.75 per cent. The sensitivity and specificity of palpation of the cervical lymph nodes were 66.66 per cent and 87.55 per cent respectively. It may be concluded that high-resolution real-time US is a sensitive, simple and inexpensive method for evaluating laryngeal cancers and subclinical cervical lymph node metastasis.

Is routine bilateral neck dissection absolutely necessary in the management of N0 neck in patients with supraglottic carcinoma

The supraglottic larynx has a rich lymphatic network that places patients with supraglottic laryngeal carcinomas at high risk for early dissemination of the disease into the cervical lymphatics. Therefore, elective neck treatment of clinically N0 neck in patients with supraglottic carcinomas is widely accepted as a standard approach. However, the issue whether elective neck treatment should routinely be directed on both sides of the neck is still controversial. The present study is aimed at determining whether T2–T4 stage supraglottic carcinomas require bilateral neck dissection in the management of N0 necks. We designed a prospective study on 72 patients with N0 supraglottic laryngeal carcinoma. Patients were divided into three groups according to the site and extension of the primary tumors. Group I consisted of 21 patients with lateralized (clear lateral) lesion reaching but not crossing the midline. Group II comprised 25 patients with cancer largely involving one side and crossing to the midline. Group III included 26 patients with carcinoma equally involving both sides of the larynx or growth into the midline larynx. All patients underwent bilateral lateral neck dissection in conjunction with various types of laryngectomies selected to the status of the primary. Of the 72 patients, 16 were found to have occult regional metastases in pathologic examination (9 pN1, 4 pN2b, 3 pN2c). The prevalence of occult metastases proportionally increased with T stage from 8.3 to 22.7 and 31.2%, respectively, for T2, T3 and T4. Bilateral neck metastases were found in 2 of 26 patients (7.7%) with central lesions. There was only one patient (4%) with both ipsilateral and contralateral lymph node metastasis in group II. None of the 21 patients with lateral lesion (group I) had contralateral neck metastasis. Routine bilateral elective neck dissection may not be a part of the surgical procedure in all supraglottic laryngeal carcinoma patients. Bilateral neck dissection should be preferred for cases with central tumors and lateral tumors with positive nodes in the ipsilateral side of the neck.

The role of CD44 and matrix metalloproteinase–9 expression in predicting neck metastasis of supraglottic laryngeal carcinoma☆☆☆

AIM The aim of this study is to evaluate the role of CD44 and matrix metalloproteinase (MMP)-9 expression in predicting neck metastasis of supraglottic laryngeal carcinoma. MATERIALS AND METHODS Two hundred ninety-four supraglottic laryngeal cancers were treated surgically from 1991 to 2005. Ninety-four of the 294 patients had pathologically metastatic lymph node (pN+). Among the 94 patients, 30 pN+ patients were selected via random sampling. Sex-, T value-, and differentiation-matched 30 patients who had pathologically negative neck were also selected. CD44 and MMP-9 antibodies were applied to the tumor representative sections that were derived from paraffin sections by using the streptavidin-biotin method. The association between immunohistochemical results and histopathologic lymph node metastasis was analyzed statistically. The association between immunostaining of CD44 and MMP-9 was also analyzed. RESULTS Overexpression of CD44 and MMP-9 was found to be significantly higher in pN+ patients. There was fair concordance between immunostaining of CD44 and MMP-9. CONCLUSION Although wider multiinstitutional and multidisciplinary studies are needed to draw specific conclusions, CD44 and MMP-9 can be useful in the prediction of neck metastasis in the supraglottic laryngeal carcinoma.

Tularemia: a rare cause of neck mass, evaluation of 33 patients

The objective of the study is to report 33 cases presenting with neck masses later diagnosed with tularemia and to raise attention to this rare zoonotic infection. A retrospective analysis of 33 patients, who were diagnosed with tularemia and treated at Erciyes University Department of Otorhinolaryngology between January 2010 and December 2010 was conducted. In conclusion, because tularemia is a rare infection, its diagnosis is frequently delayed and the symptoms of the patients may last for months without any appropriate treatment. The diagnosis of tularemia rests on clinical suspicion. For the patients, who carry risk factors for tularemia and having cervical lymphadenopathies with or without oropharyngeal symptoms and who do not response to treatment with beta-lactam antibiotics, tularemia must be kept in mind.

Inflammatory myofibroblastic tumor of the nasal cavity : a case report and review of the literature

Our aim is to describe clinicopathological, histochemical, and immunohistochemical findings of one case of inflammatory myofibroblastic tumor of the nasal cavity. A 10-year-old female presented with a short history of nasal obstruction, epistaxis, nasal discharge and headache. Computerized tomography (CT) scans showed a space-occupying lesion in the right nasal cavity. Histological examination of initial biopsy showed fascicles of spindle cells in a mixed inflammatory background with a predominance of plasma cells, typical of inflammatory pseudotumor. The spindle cells were positive for vimentin and actin. The mass was completely excised without any difficulty under generalized anesthesia. Inflammatory myofibroblastic tumor of the nasal cavity is a localized and completely benign lesion. Simple complete excision is curative.

Functional surgical approach to the level I for staging early carcinoma of the lower lip.

OBJECTIVE: The management of the neck in patients with T1-T2 carcinoma of the lower lip (LLC) remains controversial. Suprahyoid neck dissection seems a reliable diagnostic approach, although it sacrifices the submandibular gland and its vascularity. STUDY DESIGN AND SETTING: This study was a prospective, randomized study. Patients with previously untreated T1 or T2 primary LLC underwent either classical suprahyoid neck dissection (CSHD) or functional suprahyoid neck dissection (FSHD) in continuity with the resection of the cancer of the lip. RESULTS: A total of 48 suprahyoid neck dissections were performed in 36 patients. Among these dissections, 27 were CSHD and 21 were FSHD. The average number of dissected lymph nodes was similar for both classical and functional type operations. The overall follow-up period was 40.5 months. CONCLUSIONS: The end result of this series supports the idea that FSHD is a reliable diagnostic method for the management of level I lymph nodes in LLC. FSHD can avoid undertreatment or overtreatment of the patients with early LLC while preserving the submandibular gland.

Extranasopharyngeal angiofibroma originating from the nasal septum.

Angiofibroma arising outside the nasopharynx is unusual. The nasal septum is an extremely rare site for an angiofibroma to originate, and, to date, only 3 cases have been reported in the literature. We reported here the fourth case of nasal septal angiofibroma. A 27-year-old male patient with nasal deformity applied to the Erciyes University ENT Department. He also complained of nasal obstruction on the right for 6 years. Two years ago, he had experienced an epistaxis, which oozed for 2 weeks after being packed. Neither the patient nor his family had a history of any hematologic disorder. On examination, an external nasal deviation to left was remarkable. A dark grayish mass was seen through the right nostril, between the nasal septum and the inferior turbinate on anterior rhinoscopy. There was no mass in the nasopharynx on posterior rhinoscopy via endoscope. http://www.entnet.org/journal/casereports/OTO-24.pdf/

Management of no Neck in T1-T2 Unilateral Supraglottic Cancer

Early-stage supraglottic cancers (stage I and II) are treated with several different programs. Previously reported data have led us to design a therapeutic protocol in treatment of patients with early-stage squamous cell carcinoma of the supraglottic larynx. From 1991 to 1996, 39 patients with unilateral supraglottic carcinoma were treated according to this protocol. All patients underwent unilateral functional neck dissection and resection of the primary carcinoma in an en bloc fashion. Histopathologic studies showed that 9 (23%) of them had positive nodes, and they received planned adjuvant radiotherapy. None of the 30 patients with histopathologically NO necks received either adjuvant irradiation or contralateral neck dissection. The mean follow-up period was 34 months. All patients are alive, and none have developed any recurrence in either dissected or undissected sides of the neck. This treatment policy seems satisfactory and will avoid unnecessary therapeutic interventions. Routine bilateral neck dissection may not be necessary in the surgical treatment of all supraglottic laryngeal cancers.
