Reviewing the clinic cases of two patients bearing with asymptomatic p
leural lipoma, whose general course and treatment of their disease wer
e very different, it seemed useful to us to focus on such a benign unc
ommon tumor. We therefore analysed this tumour's features, especially
its scanographic characteristics, its spontaneous evolution, and its p
otential complications, in order to avoid diagnostic thoracotomy as fa
r as possible.
