Endotype of Chronic Rhinosinusitis with Nasal Polyps in Morocco.

Background: With the advent of biotherapies, endotyping of chronic rhinosinusitis with nasal polyps (CRSwNP) is becoming more and more important to optimize therapeutic management. While the majority of CRSwNPs in the United States, Europe, and Japan exhibit type 2 eosinophil-dominant inflammation response, other parts of Asia display mixed patterns including neutrophil-dominant inflammation. Until now, no study has focused on the proportion of inflammation patterns in Morocco or anywhere on the African continent.

The impact of the ultrasound classification on the rate of thyroid surgery indications: a 577 cases series.

Objectives: Nodules of the thyroid gland are common but rarely malignant. Their management can range from simple monitoring to surgery. The use of ultrasound and fine needle aspiration can reduce the rate of unnecessary surgeries.

SYNCHRONOUS OCCURRENCE OF THREE DIFFERENT THYROID TUMORS.

Background: Thyroid nodules are common; however, the association of two or more different tumors in the thyroid gland is unusual. We present a first case with the association of three histological types of thryroid tumors. To the best of our knowledge, this association has not been reported in the literature before.

Carotid Body Tumors: A Case Series and Review of the Literature.

Background: Paragangliomas of the head and neck are rare vascular tumors derived from the paraganglia tissues originating from the neural crest. They are usually benign and hypervascularized. Diagnosis is relatively easy in condition to consider it in evaluating every lateral neck mass.

Spontaneous cerebrospinal fluid leak of the sphenoid sinus mimicking allergic rhinitis, and managed successfully by a ventriculoperitoneal shunt: a case report.

Background: Spontaneous cerebrospinal fluid leaks are rare but may lead to confusion with other diseases in patients without history of trauma. We report a rare case unusual for two reasons. First, our patient was put under antiallergic medication for months before the diagnosis of spontaneous cerebrospinal fluid leak of the sphenoid sinus.

[Primary intraosseous mucoepidermoid carcinoma of the jaws].

Introduction: A mucoepidermoid carcinoma (MEC) is a malignant salivary gland tumor. Its primitive intraosseous maxillary localization is rare. We report a case with a difficult diagnosis.
