Histological surprise of parotid tuberculosis: about two cases.

Parotid tuberculosis remains a very rare localization in the Department of Otolaryngology and Cervico-Facial Surgery (ENT) sphere. It is presented in the form of a deceptive clinical picture causing confusion with other pathologies of the parotid gland, including tumor pathology. In addition, its lack of knowledge by practitioners increases the risk of missing the diagnosis. Often, the diagnosis is a histological surprise on a piece of excision after an exploratory parotidectomy. However, its treatment is primarily medical if the positive diagnosis is well established. We report medical observation of two new cases aged 44 and 45 respectively, who consult our center for parotid swelling. Radiological examinations were in favor of intraparotid cystic lesions. Both patients benefited from an excision whose histopathological study was in favor of primary parotid tuberculosis. The subsequent evolution was favorable under antituberculous treatment.

An unusual presentation of neurosarcoidosis with progressive hearing loss.

Sarcoidosis is a granulomatous disease of unknown etiology that can involve several organ system. Neurological manifestations are not common and mostly include cranial neuropathies. However, auricular disorders are rare and exceptionally inaugural. We describe the case of a 46-year-old lady presented with hearing loss as the initial manifestation of sarcoidosis, and aim to raise awareness of this condition, that is often associated with significant morbidity.

[Cervicothoracic cystic lymphangioma: about a case]. / Lymphangiome kystique cervico-thoracique: à propos d'un cas.

Cervicothoracic cystic lymphangiomas are rare benign tumors developing from sequestration of embryonic lymph sac which is gradually filled with lymph fluid. The diagnosis is based on clinical signs (laterocervical swelling) and imaging (ultrasound and CT scan), then confirmed by histology after surgery which constitutes the basis of treatment. We here report a case of cervicothoracic cystic lymphangioma and review of the literature.

Association of laryngeal and nasopharyngeal tuberculosis: a case report.

INTRODUCTION: To the best of our knowledge, the association of nasopharyngeal and laryngeal tuberculosis has never been described before in the literature. We report here a first observation. CASE PRESENTATION: We report the case of a 38-year-old Arab man who presented with an isolated hoarseness. Radiological and endoscopic examinations showed a thickening of the left lateral wall of his nasopharynx and the left vocal cord. Pathology revealed the diagnosis of tuberculosis of both localizations. He received a 6-month antituberculous chemotherapy with a satisfying uneventful evolution. CONCLUSIONS: Tuberculosis should be considered in the differential diagnosis of soft tissue masses of the head and neck, particularly when the imaging findings and clinical presentation are atypical. The diagnosis of tuberculosis is mainly based on histopathological and/or bacteriological examination.

Adenocarcinoma of the sphenoid sinus.

Adenocarcinomas of the sphenoid sinus are exceptional. In this paper, we report a new case with a review of the literature. Our patient was a 45-year-old man who presented with isolated retro orbital headache. CT and MRI suspected a malignat tumor of the sphenoid sinus. The patient underwent a debulking surgery. The final pathology carried out the diagnosis of primary adenocarcinoma. The patient died several months later from radiotherapy complications. Even if adenocarcinomas of the sphenoid sinus are exceptional, they should be considered in the differential diagnosis of sphenoid sinus masses. The prognosis is poor.

Chondrosarcoma metastasis in the thyroid gland: a case report.

INTRODUCTION: Chondrosarcoma metastases in the thyroid gland are exceptional. To the best of our knowledge, only two cases have been previously reported in the literature. Here we report the third case. CASE PRESENTATION: We report the case of a 51-year-old Arab woman who presented in 2011 with a diaphyseal chondrosarcoma of her right tibia treated by surgery. In the last quarter of 2013, she presented a hard mass in her thyroid gland with dyspnea and a right laryngeal paresis. She underwent a debulking surgery with tracheostomy in order to prevent difficulty in respiration. The final pathology revealed the diagnosis of a chondrosarcoma metastasis within her thyroid gland. She died several days later. CONCLUSIONS: Even if primary and metastatic chondrosarcomas of the thyroid gland are exceptional, they should be considered in the differential diagnosis of thyroid gland masses. The prognosis is poor but surgery may help preserve quality of life.
