RESUMEN
This report presents a rare case of bronchogenic adenocarcinoma with initial metastasis in the external auditory canal. The patient, a 64-year-old man with a history of bladder urothelial carcinoma, initially presented with a persistent right otitis externa. Otoscopic examination revealed a mass obstructing the right external auditory canal. The temporal bone computed tomography scan revealed a mass that completely obstructed the right external auditory canal and extended into the middle ear. A biopsy showed a poorly differentiated adenocarcinoma of bronchogenic origin, confirmed by positive immunohistochemical staining for cytokeratin 7 and Thyroid transcription factor-1. Further imaging revealed a large tumor mass in the lung involving the mediastinum and parenchyma, along with carcinomatous lymphangitis and cerebral metastasis. Histopathological examination of the primary lung tumor confirmed a poorly differentiated adenocarcinoma with similar features to the metastasis in the external auditory canal. The tumor was staged as T4N2M1c, and the patient underwent local external-beam radiation therapy with chemotherapy.
RESUMEN
Fungus ball (FB) is a non invasive form of fungal sinusitis that generally affects immunocompetent subjects. Isolated involvement of the frontal sinus is extremely rare. The treatment is surgical. Previously, it was based on the external approach. Recently, the endoscopic approach has been increasingly employed. We report three cases of frontal sinus fungus ball. Two patients underwent endoscopic endonasal frontal Draf type IIb sinusotomy with complete removal of the pathologic material. The third patient had an external approach due to the extensive pneumatisation of the frontal sinus, the defect in its floor and the orbital involvement. There were no intraoperative or postoperative complications. No recurrence of the disease was observed during the three, two and twelve months' follow up period, respectively. Correct clinical and radiological diagnosis of isolated frontal sinus FB still remains a challenge. Endoscopic sinus surgery with endonasal Draf type IIb or type III frontal sinusotomy is effective for the treatment of frontal sinus FB. It is the treatment of choice and replaces the traditional external approaches.

INTRODUCTION: Myxomas are benign mesenchymal neoplasms which arise mainly in the heart. The laryngeal localization is very rare. We aim to describe the clinical, histological and therapeutic features of this condition. CASE REPORT: We report two cases of laryngeal myxomas occurred in male and female patients, presenting with a history of prolonged hoarseness. Laryngoscopy revealed a polypoid mass on the true vocal folds. The lesions were excised with cold instruments. One patient presented a recurrence 4 years after the first surgery. CONCLUSIONS: Laryngeal myxoma should be considered in case of a benign looking vocal fold lesion, especially a vocal cord polyp. Histologic exam is the only tool to confirm the diagnosis. It is treated by surgical resection. In the literature, recurrence is rare in laryngeal site, but patients need to be kept on close follow-up.
RESUMEN
Background: Hemithyroidectomy is one of the most common procedures performed. It is used to treat patients with benign unilateral nodules. Hemithyroidectomy results in fewer risks of hypothyroidism and the need for thyroid hormone replacement therapy. The present study was designed to identify potential clinicopathologic risk factors associated with the onset of biochemical hypothyroidism. Methods: We conducted a retrospective review of all patients who underwent hemithyroidectomy between 2004 and 2019. Hypothyroidism was defined as a serum thyrotropin level greater than 5 mIU/L. The patients were analyzed for age, sex, preoperative and postoperative thyroid stimulating hormone (TSH), state, side, and volume of the remaining lobe, and histologic diagnosis. Results: Hypothyroidism was diagnosed in 30.8% of 214 patients. This complication appeared in the first year in 83.3% of the cases. A preoperative TSH level greater than 1.32 mIU/l, a remaining volume of the lobe less than 3 ml, and the presence of thyroiditis were associated with a significant increase in the risk of developing hypothyroidism (p<0.01). There were no significant differences in age, sex, state, and side of the remaining lobe. The mean thyroxine dose was 57 ± 26 micrograms. Conclusions: The risk of hypothyroidism after hemithyroidectomy should be assessed prior to surgery. Close monitoring is recommended in patients at high risk of developing this complication. However, all patients who undergo hemithyroidectomy should be monitored at least for the first year.

INTRODUCTION: Organized hematoma of the maxillary sinus (OHMS) is a rare benign disease that can be locally aggressive. The diagnosis of this condition is challenging. CASE REPORTS: We report two cases of OHMS presented with recurrent nasal bleeding, nasal obstruction and anosmia. Radiological findings were suggestive of a vascularised lesion in the first case and a malignant tumor of the maxillary sinus in the second case. Both patients underwent an endonasal endoscopic surgery, There was no recurrence at 19 months' and six months' follow-up respectively. CONCLUSIONS: OHMS should be included in the differential diagnosis if a patient presents with history of recurrent epistaxis and nasal obstruction and radiological findings reveal an expansible maxillary mass with or without bone erosion. Correct preoperative diagnosis is important to avoid unnecessary extensive surgery. The prognosis is very good and minimally invasive surgery such as endonasal endoscopic surgery can cure it completely.
RESUMEN
INTRODUCTION: Chronic rhinitis (CR) is dominated by allergic rhinitis (AR) whose frequency continues to increase. Allergic rhinitis is a public health problem. The distribution of pneumallergens varies according to countries and regions. The epidemiology of pneumallergens, as well as their role in respiratory pathology, remain poorly known in the southern region of Tunisia. AIM: To evaluate the prevalence of skin-tests positivity of patients with CR in a region of southern Tunisia, to identify the main pneumallergens and to look for an epidemiological and clinical prediction of AR. METHODS: This is a retrospective study of patients with CD and residing in Sfax, performed in the ENT department of Habib Bourguiba hospital over a period of 2 years (2015-2017). RESULTS: We collected 300 patients. The diagnosis of AR was retained in 109 patients (36.3%). Mites were the most common allergens (67%) followed by dander (38.5%) and olive pollen (31.2%). Study in uni-variate analysis retained young age, presence of drug allergy, frequent sneezing, nasal hyperreactivity triad, nasal pruritus, and pharyngeal signs as predictors of AR. Multivariate analysis included age≤ 30 years (p = 0.005), frequent sneezing (p = 0.005), and pharyngeal signs (p = 0.01). CONCLUSION: AR is a common pathology in the Sfax region that mainly affects young people with signs of nasal hyperresponsiveness. The accessibility of the most common pneumallergens to eviction measures opens a better perspective of management.
