Lymphangiomatous Polyp of Tonsil: A Case Report.

Lymphangiomatous polyps of the palatine tonsils are uncommon hamartomatous proliferations that could be clinically misdiagnosed as malignant neoplasms. These polyps consist of dilated lymphatic vessels located inside fibrous and/or adipose tissue. In this paper, a 27-year-old man who presented to the outpatient clinic with a complaint of dysphagia is presented. On physical examination, the patient had a smooth, polypoid mass extending from the posterior section of the right palatine tonsil into the oropharynx. The patient underwent right tonsillectomy. Histopathological examination of the specimen showed typical features of a lymphangiomatous polyp of the tonsil. The case is reported with the accompanying literature to avoid the possibility of misdiagnosing it as a malignant lesion clinically.

Cyclooxygenase-2 expression and clinical parameters in laryngeal squamous cell carcinoma, vocal fold nodule, and laryngeal atypical hyperplasia.

BACKGROUND: The diagnostic role of cyclooxygenase-2 (COX-2) expression in laryngeal atypical hyperplasia, vocal fold nodule, and laryngeal squamous cell carcinoma was examined. METHODS: Specimens obtained from patients diagnosed with vocal fold nodule (n = 35), atypical hyperplasia (n = 35), laryngeal squamous cell carcinoma (n = 35), and clinical parameters were evaluated retrospectively. RESULTS: Although no staining was observed in patients with vocal fold nodules, staining was noted in laryngeal atypical hyperplasia and squamous cell carcinoma. The percentage of COX-2 staining was the highest in the carcinoma group. CONCLUSION: It was determined that COX-2 staining was significantly associated with laryngeal squamous cell carcinoma. It should be noted that overexpression of COX-2, a potentially important factor in the evolution of carcinogenesis in precancerous lesions, might be an indicator of the development of carcinoma.

Adenocarcinoma arising in warthin tumor of the parotid gland.

Warthin tumor is a well-defined benign salivary gland neoplasm consisting of both epithelial and lymphoid components. The tumor is the second most common benign tumor next to pleomorphic adenoma. We present a case of adenocarcinoma, not otherwise classified, arising in unilateral Warthin tumor of the parotid gland in a 63-year-old male patient. Carcinomas arising in or from the epithelial component of a preexisting parotid Warthin tumor are rare and differential diagnosis of metastasis from an adenocarcinoma in Warthin tumor is important. The patient underwent a complete and thorough work-up, and no other primary malignant lesion was found. No other primary malignant lesion had manifested at the last one year follow-up period.

Analysis of the roles of smoking and allergy in nasal polyposis.

OBJECTIVES: Recent studies on the etiopathogenesis of nasal polyps have shown that smoking and nonallergenic inhalants such as occupational dust exposure cause chronic inflammation of the nasal mucosa. These factors may be associated with nasal polyps. The aim of this study was to use laboratory tests to investigate the effects of smoking and allergens on the development of nasal polyps. METHODS: The study included 60 consecutive patients with a diagnosis of nasal polyposis who were treated with functional endoscopic sinus surgery at our clinic and 25 smoker and 25 nonsmoker participants who constituted a control group. RESULTS: In the patient and control groups, the mean absorbance value for cotinine in smokers was found to be statistically significantly lower than that in nonsmokers. There was a significant difference between the groups with respect to blood cotinine positivity. No significant difference was found between the groups in terms of allergy parameters. In the regression model, smoking was found to be the only significant risk factor for the development of nasal polyps, independent of smoking duration, absorbance value, or cotinine positivity. CONCLUSIONS: Smoking restriction and avoiding exposure to cigarette smoke by patients with nasal polyps may be an important strategy in the prevention and recurrence of nasal polyposis. No direct relationship was determined between allergy and nasal polyposis.

Rhinolithiasis: review of 21 cases.

BACKGROUND: Rhinolithiasis is masses that result from the deposition of salts around an intranasal foreign body. Rhinoliths are rare and rhinolithiasis is generally reported in the literature in single case studies. This study presents 21 cases of rhinolithiasis with a large series of clinical findings, diagnosis, and treatment. METHODS: A total of 21 patients diagnosed with rhinolithiasis were identified. Clinical presentations, signs, and symptoms of the patients with radiological findings are presented, and x-ray diffraction analyses of three of the removed rhinoliths were performed to assess their mineralogical composition. RESULTS: A total of 21 patients (9 male and 12 female patients; age range, 4-63 years) diagnosed with rhinolithiasis were reviewed in this study. The most common symptoms were noted as purulent rhinorrhea and nasal obstruction. The other symptoms were headache, oral malodor, and recurrent epistaxis. Nasal endoscopic examination was used for diagnosis of all patients. Endoscopic nasal examinations and computerized tomography (CT) findings revealed that rhinolithiasis was accompanied by sinusitis, chronic vestibulitis, allergic rhinitis, septum deviation, and squamous cell carcinoma. Rhinoliths were fully excised by using endoscopic nasal surgery. Mineralogical analyses of the three removed stones revealed dahllite [Ca(5)(PO(4),CO(3))(3)OH]. CONCLUSION: Cases of rhinolithiasis are seen rarely. It should always be considered in patients complaining from long-term unilateral nasal obstruction and unilateral purulent rhinorrhea. The treatment involves the removal of the rhinolith and the use of appropriate antibiotic therapy to control local infection. Rigid nasal endoscopy is the most important method to be used in diagnosis and treatment.
