Parietal Thoracic Tuberculosis: A Report of Two Cases.

Parietal thoracic tuberculosis is a rare localization of tuberculosis. It reaches the ribs and intercostal spaces due to hematogenous spread or direct transcutaneous inoculation. The diagnosis of tuberculosis must be evoked given the endemic context, even in immunocompetent patients. Surgical excision associated with medical treatment remains the best treatment in this case to avoid any local or distant recurrence.

Primary leiomyoma of the lung: an exceptional localization.

Leiomyoma is a benign smooth muscle tumor usually encountered in the uterus. Primary pulmonary localization is extremely rare in adults and children. However, it must be included in the differential diagnosis of any nodular lung lesion. Its treatment is surgical, with good long-term results. Here, we report a case of leiomyoma of lung parenchyma diagnosed in a 26-year-old man.

[Spontaneous pneumothorax: unusual manifestation of pulmonary hamartochondroma]. / Pneumothorax spontané: mode de révélation inhabituel d'un hamartochondrome pulmonaire.

Hamartochondroma is a benign tumor of the tracheobronchial tree, often found incidentally and rarely symptomatic. It is more common in men than in women. Its radiological aspect is often evocative. Surgery is indicated for large and/or symptomatic tumors. Histological diagnosis usually poses no difficulty We report the case of a 30-year-old young patient with no particular past medical history and with spontaneous pneumothorax revealing a large sized hamartochondroma. This rare association could be explained by the fact that tumors of fairly anarchic composition may contain cyst formations that may rupture into the pleura causing effusions.

Mediastinal hydatid cyst: a case report.

INTRODUCTION: Mediastinal localization of hydatidosis is very rare even in endemic areas. The diagnosis is based on typical clinical and radiological criteria. CASE PRESENTATION: We report a case of a mediastinal location of hydatidosis in a 60-year-old Arab man admitted for chest pain. The chest radiograph showed a rounded and homogeneous opacity. Computed tomography showed a right mediastinal cyst, without other thoracic or abdominal sites. Through a posterolateral thoracotomy, we found a cystic mass in the posterior mediastinum. The patient received a cystectomy with medical treatment based on albendazole. He improved a few weeks later. CONCLUSION: Mediastinal cysts remain rare, even in endemic countries, which makes initial diagnosis difficult. Our observation shows the importance of keeping this diagnosis in mind when a patient presents with signs of mediastinal compression.
