[Cardiac metastasis of bronchial squamous cell carcinoma]. / Métastase cardiaque d'un carcinome épidermoïde bronchique.

Secondary location of lung cancer are frequent but the location heart is rare and often diagnosed postmortem. We report a case of a patient of 67 years without disease history, individuals smoking outside a chronic carrier of bronchial squamous cell carcinoma and the staging of which finds a secondary location within the left atrial. Through this observation, the authors propose an update on this rare and exceptional location.

[Doege-Potter syndrome. about one new case]. / Syndrome de Doege-Potter : à propos d'une nouvelle observation.

Syndrome Doege-Potter is a paraneoplastic syndrome in which hypoglycemia is the result of tumors producing insulin growth factor-like (IGF-II) it is most often solitary fibrous tumor of the pleura (TFSP). These are rare and may be discovered incidentally, during non-specific respiratory symptoms or during hypoglycemia. Hypoglycemia occurs in tumors of large volume and it disappears after surgery, which is the treatment of choice for a permanent cure in most cases. We present a case of Doege-Potter syndrome whose interest is to consider the TFSP as a cause of hypoglycemia in patients with pleural tumors.

[Thoracic actinomycosis: three cases]. / L'actinomycose thoracique. A propos de trois cas.

Actinomycosis is a rare condition which, in the thoracic localisation, can mimic cancer or tuberculosis. We report a series of three case of thoracic actinomycosis treated in the Ibn Sina University Thoracic Surgery Unit in Rabat, Morocco. CASE N degrees 1: This 45-year-old patient presented a tumefaction on the left anterior aspect of the chest. Physical examination identified a parietal mass with fistulisation to the skin. Radiography demonstrated a left pulmonary mass. Transparietal puncture led to the pathological diagnosis of actinomycosis. The patient was given medical treatment and improved clinically and radiographically. CASE N degrees 2: This 68-year-old patient presented repeated episodes of hemoptysis. The chest x-ray revealed atelectasia of the middle lobe and bronchial fibroscopy demonstrated the presence of a bud in the middle lobar bronchus. Biopsies were negative. The patient underwent surgery and the histology examination of the operative specimen revealed pulmonary actinomycosis. The patient recovered well clinically and radiographically with antibiotic therapy. CASE N degrees 3: This 56-year-old patient presented cough and hemoptysis. Physical examination revealed a left condensation and destruction of the left lung was noted on the chest x-ray. Left pleuropulmonectomy was performed. Histological analysis of the surgical specimen identified associated Aspergillus and Actinomyces. The outcome was favorable with medical treatment. The purpose of this work was to recall the radiological, clinical, histological, therapeutic, outcome aspects of this condition and to relate the problems of differential diagnosis when can suggest other diseases.

[Tracheal scleroma and rhinoscleroma: a case report]. / Le sclérome trachéal et le rhinosclérome. A propos d'un cas.

Scleroma is a specific granlomatous disease caused by an enterobacteria of the Klebsiella family (Klebsiella rhinoscleromatis), localized electively in the upper airways, particularly the nasal fossae, leading to the term "rhinoscleroma". Tracheal involvement is exceptional. The disease progresses slowly, leaving mutilating and stenosing scar tissue. Medical treatment using antibiotics and corticosteroids is the basic approach although surgical treatment may be needed for fibrosclerosis unresponsive to medical treatment. We report a case of rhinoscleroma which extended to the trachea. In light of this case, we examine the demographic, diagnostic, therapeutic and evolutive aspects of this disease.

[Pulmonary actinomycosis with chest wall fistula formation]. / L'actinomycose pulmonaire fistulisée à la paroi thoracique.

INTRODUCTION: Actinomycosis is a suppurative infection caused by bacteria of the genus actinomyces. It is a rare cause of pulmonary infection and can be difficult to diagnose as its presentation may mimic cancer or tuberculosis. In the absence of treatment of pulmonary lesions fistulae can develop. We report a case of pulmonary actinomycosis complicated by a chest wall fistula that was managed by the thoracic surgery unit at Chu Ibn Sina de Rabat. CASE REPORT: A 45 year old man who was previously fit and well presented with a left sided chest wall swelling with cutaneous fistulae. Pulmonary auscultation revealed evidence of left apical consolidation. Otherwise clinical assessment was unremarkable. Plain chest radiology revealed left apical opacification. CT scanning revealed a left pulmonary mass and percutaneous biopsy confirmed the diagnosis of actinomycosis. The patient was started on treatment and experienced a clinical and radiological improvement sustained at one year's follow up. CONCLUSION: We review the clinical and radiological characteristics of this condition as well as diagnostic difficulties, histological findings, therapeutic options and its natural history.

[Primary pulmonary angiosarcoma]. / Angiosarcome pulmonaire primitif.

INTRODUCTION: Primary pulmonary angiosarcoma (PPA) is a very rare tumour with a grave and short prognosis and whose primary site is difficult to confirm. The diagnosis is essentially histological and immunohistochemical because there are no specific clinical or radiological signs. OBSERVATION: We report a case of a man with PPA, discovered during the investigation of chest pain. Imaging (x-ray and CT) identified a right apical mass. The diagnosis was made by histological and immunohistochemical analysis of CT guided percutaneous biopsies. CONCLUSION: As a result of this observation we propose further studies on this extremely rare and grave condition.
