[Disseminated ossification of the lung].

Disseminated pulmonary ossification is a rather rare finding. Two classical cases of the dendriform and seven of the nodular one, even if with minimal aspects, were reported. They were found through a revision of 720 postmortem registers and a reexamination of their histological specimens. A typical morphologic picture was observed. About formal genesis of the bone we emphasized the possibility that the ossification occurred in the dendriform also through a cartilaginous phase in addition to a connective one. Various pathological forms of the lung or other organs, that on the basis of the literature are considered responsible or associated with pulmonary ossification, were listed. Eventually, we pointed out that dendriform could be a pathological picture by itself and not a secondary one, that is to say a real idiopathic ossification.
