Tuberculose de l’omoplate chez l’enfant: à propos d’une localisation exceptionnelle

La tuberculose osseuse est une maladie infectieuse qui constitue un véritable problème de santé publique dans les pays en voie de développement où elle sévit de manière endémique. L'atteinte ostéo-articulaire représente 1 à 5% des cas de tuberculose toutes localisations confondues, l'atteinte de l'épaule reste très rare et représente 1 à 2% des localisations ostéo-articulaires. Nous présentons ici un nouveau cas exceptionnel d'une infection tuberculeuse de l'omoplate, atteignant le corps de l'omoplate. La tuberculose est encore un diagnostic différentiel important des maladies rares ou chroniques des os, notamment tumorales. Le diagnostic a été redressé par l'étude anatomopathologique.Mots clés: Omoplate, tuberculose, enfantEnglish Title: Scapular involvement: uncommon presentation of childhood tuberculosisEnglish AbstractTuberculosis of bone is an infectious disease which represents a major public health problem in developing countries where it is endemic. Osteoarticular involvement accounts for 1-5% of all cases of tuberculosis, shoulder involvement is very rare and accounts for 1-2% of all cases of osteoarticular tuberculosis. We here report an uncommon case of TB infection involving the scapula, reaching the scapular body. Tuberculosis is still an important differential diagnosis of rare or chronic bone diseases, including tumors. In our study anatomopathological examination led to the diagnosis.Keywords: Scapula, tuberculosis, chil

A Rare Case of Malignant Tumor of the Larynx with Good Prognosis: Laryngeal Chondrosarcoma

Laryngeal chondrosarcoma is a rare laryngeal tumor that most frequently originates from the cricoid cartilage. The majority of lesions are low grade and the distinction from benign chondromas must be made. We present a case of a laryngeal chondrosarcoma arising from the cricoid cartilage in a 75-year-old Arab man who presented with hoarseness, dysphonia, and dyspnea. Endoscopic and radiological examinations showed a mass of the wall of his larynx with displaced structures, airway obstruction, and destruction of the cartilage. The patient underwent total laryngectomy. Histological examination supported the diagnosis of low-grade chondrosarcoma. Five months later, the radiological and clinical findings showed no evidence of recurrence or metastases. Laryngeal chondrosarcomas remain a rare disease of unknown etiology, with slow and insidious symptoms. The treatment is surgical, given the importance of preserving the larynx to patients’ quality of life. The prognosis is favorable and metastases rarely occur
