[Chronic pseudo-hypertrophic myopathy in sarcoidosis. Apropos of 3 cases].

We report three cases of pseudohypertrophic chronic myopathy in patients with sarcoidosis. The patients were aged 41-50 years and were of African or mixed ethnic origin. All three patients had multiorgan sarcoidosis recently diagnosed by the presence of hiliary and/or mediastinal node enlargement with or without reticulomicronodulation in the lung fields.

[Late relapse of sarcoidosis. Report of 3 cases].

We report patients who were treated with corticosteroids for sarcoïdosis and developed recurrent disease after 9 and 28 years of remission. The clinical latency, the type III radiographic aspect different from the initial presentation and the spontaneous course with periods of partial or total remission are characteristic of these late relapses. Clinicians should be aware of this uncommon clinical course and monitor cured cases for prolonged periods.

[Peritoneal pseudomyxoma with pleural metastases. A case report].

The authors report a case of a 69 year old man with a peritoneal pseudo-myxoma probably secondary to a mucocele of the appendix and complicated by pleural metastases which were nodular, unilateral and asymptomatic. These were discovered on computerised tomography during examination for the recurrence of the peritoneal disease. A study of the histology of the pleural fragments obtained by thoracotomy showed the presence of lesions which were identical to those found in the peritoneal masses.

[Mycoplasma pneumoniae infections].

Mycoplasma pneumoniae is a pathogenic micro-organism frequently held responsible for acute respiratory infection. The disease is ubiquitous and often proceeds in epidemics among small communities of young people (families, army barracks, universities). Its usual clinical manifestations consist of a stubborn cough symptomatic of tracheo-bronchitis with or without fever, and inflammation of the upper respiratory tract.
