[Solid pleural-based mass as initial manifestation of non-Hodgkin's lymphoma]. / Localisation tumorale solide sous-pleurale revelatrice d'un lymphome non-Hodgkinien.

Subpleural involvement is a well-known site of advanced or recurrent lymphoma. But, to our knowledge, it has never been described as an initial manifestation of this disease. We report the case of a patient with solid subpleural mass revealing a non-Hodgkin's lymphoma.

[Spontaneous dissection of coronary arteries. Apropos of 2 new cases with favourable course]. / Dissections spontanées des artères coronaires. A propos de deux nouveaux cas avec évolution favorable.

The authors report two new cases of spontaneous coronary dissection and discuss the real frequency of this disease as well as their generally reported poor prognosis. One case was a 32-year-old female migraine-sufferer treated by beta-blockers, who developed a rudimentary anterior myocardial infarction. The other case was a 43-year-old man who presented with a threatened anterior myocardial infarction without myolysis documented by cardiac enzymes. Both patients were smokers and both had an excellent outcome, clinically and on stress tests, with a follow-up on medical treatment alone of thirty months for the first case and fourteen months for the second case. These two new cases had a good prognosis, in contrast with the majority of cases published.
