RESUMO

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.

RESUMO

OBJECTIVES: Vocal dysfunction is a frequent complication following thyroidectomy that can be associated with a negative impact on patients' quality of life. Although the effect of thyroidectomy on acoustic features has been widely studied, the examination of glottal flow characteristics to assess vocal outcomes following thyroid gland surgery has not been included in empirical research, to date. The goal of our study was to evaluate early and short-term vocal outcomes following thyroidectomy based on the analysis of glottal acoustic features during speech production. STUDY DESIGN: Prospective analytical study. MATERIALS AND METHODS: We evaluated vocal outcomes in patients who underwent thyroidectomy between September 2021 and March 2022. We extracted glottal flow features from their vocal recordings preceding surgery and postoperatively at Day1 and Month1 postoperatively. The extraction of glottal features was performed using a signal processing-based approach. We extracted the following features: Open quotients (OQ1 and OQ2), Quasi-open quotient (QoQ), Closing quotient (ClQ), Amplitude quotient (AQ), Normalized Amplitude quotient (NAQ) and Speed quotients (SQ1 and SQ2). We included 39 patients. OQ2 and QoQ decreased significantly at Day1 and Month1. OQ1 and NAQ decreased significantly at Month1. ClQ remained stable at both postoperative assessments. AQ decrease was not significant at both dates. SQ1 increased at Day1 and Month1 but the change was not significant. SQ2 decreased significantly at both Day1 and Month1. OQ, QoQ, AQ, NAQ, and SQ2 did not recover at Month1. We noted that the decrease of SQ1 and SQ2 correlated significantly with the increase of the Voice Handicap Index-10 (VHI-10) at Month1. CONCLUSION: The analysis of glottal acoustic features can be a reliable modality to detect vocal changes following thyroidectomy. Thyroidectomy was associated with a vocal dysfunction that was manifested by the decrease of open, amplitude, and speed quotients. Glottal features can present a potential tool to objectively assess the effect of thyroidectomy on vocal folds movements.

RESUMO

This report describes the unique case of a 37-year-old pregnant patient with a history of total thyroidectomy who presented worsening dyspnea due to a recurrent benign goiter. The goiter grew through the tracheal wall and narrowed the tracheal lumen. After unsuccessful treatment with bronchodilators and corticosteroids, the patient underwent an emergency tracheostomy and cesarean section. Cervicothoracic computed tomography revealed a 4 cm mass in the left lobe of the thyroid gland with endotracheal extension in the subglottic region. Exploratory cervicectomy revealed a macroscopically resected mass that resembles the structure of the thyroid, adherent to the esophagus, anterior to the cricoid cartilage, and the trachea. Intratracheal thyroid tissue was not excised due to the increased risk of bleeding, and endoscopically guided biopsies were performed. Histopathological examination confirmed the benign nature of the thyroid tissue. A follow-up computed tomography scan after 2 months showed spontaneous regression of the intratracheal mass, and the tracheostomy tube was successfully removed without complications.

RESUMO

Salivary gland tumors in children are rare; involvement of accessory salivary glands is exceptional. We report a case of pleomorphic adenoma of the palate in a child (an 8-year-old girl) addressed by her dentist for discovering a swelling in the palate. Clinical examination revealed a firm, non-tender, nodular swelling in the left hard palate, measuring 1.5 cm × 1.5 cm, situated adjacent to the upper left second molar. Physical examination did not show signs of inflammation or surface ulceration. Oral cavity computed tomography scan did not show bone lysis. The tumor was removed with negative margins. No recurrence was noted. We aim to describe the clinical, radiological features, as well as the management of this rare localization of pleomorphic adenoma.

RESUMO

Mucormycosis is a serious and relatively rare invasive fungal infection. The rhino-orbito-cerebral localization is the most frequent. Other localizations have been reported including: cutaneous, pulmonary, disseminated, gastrointestinal, and miscellaneous. Mucormycosis of external ear with facial palsy is extremely rare and only few cases have been reported in the literature. We describe a case of mucormycosis of the external and middle in a 44-years-old diabetic patient which had a very aggressive form of necrotic infection of the ear auricle complicated by parotid abscess, facial, and vagal nerve paralysis. Auricular mucormycosis was suspected and the diagnosis was established after biopsy and histological examination. The patient was treated immediately with intravenous amphotericin B followed by extensive surgical debridement of the necrotic lesions. The patient responded well to the treatment despite the persistence of facial palsy.
