Schwannomas are benign tumors originated in the neural crests derived from Schwann cells. It is rarely seen in the nose and paranasal sinuses, and it very rarely originates from the nasal septum. We report the case of a 56 year-old male admitted to the Department of Otolaryngology-Head and Neck Surgery at Avicenna Military Hospital in Marrakesh (Morocco), with the complaint of a progressive left nasal obstruction since the last 9 months. Local examination and rigid endoscopy showed a smooth polypoid lesion completely filling the left nasal fossa, with a pedicle in the posterior septum region. Contrast enhanced computed tomography and magnetic resonance imaging suggested a benign origin. The tumor was completely removed via an endoscopic approach and histopathologic examination revealed a schwannoma.

Introduction: Inflammatory myofibroblastic tumors (IMTs) arising in the mediastinum is rare. Their etiology remains unknown and their diagnosis is often overlooked before the use of surgery wich allow the propre diagnosis and adequate treatment.Case report: We report a case of 56-year-old woman that had a mediastinal mass  discovered after a long complains of chest discomfort. Chest contrast-enhanced computed tomography (CT) showed a heterogeneously enhanced   mass in the middle mediastinum The diagnosis was confirmed by histopathology and immunohistochemical study   after surgical resection through a thoracotomy   The patient was well and had no recurrence 6 months after surgery.Conclusion: The diagnosis of IMT should be kept in mind and included in the differential diagnosis of mediastinal masses.

Solitary fibrous tumors are relatively rare neoplasms that commonly occur in the pleura, especially visceral pleura. However, an intrapulmonary site of this kind of tumors is even rarer. These tumors can be characterized by a heterogeneous evolution and have a benign or malignant behavior. Wide surgical resection is essential to cure the patient and to avoid recurrence. We present here the clinical, imaging, and histological features of a case with solitary fibrous tumor growing inside the lung.

Le myofibroblastome de type mammaire (MM) est une tumeur mésenchymateuse bénigne rare initialement décrit dans le sein. Le diagnostic de cette entité repose sur un spectre d’arguments cliniques radiologiques et éventuellement histologiques. Nous rapportons un cas rare de myofibroblastome de type mammaire siégeant au niveau axillaire chez un homme de 50 ans. La particularité de notre cas est l’existence de plusieurs figures de mitoses et ceci est rarement décrit dans la littérature. A travers ce cas nous soulevons les problématiques du diagnostic différentiel de cette tumeur rare.
