Dendriform pulmonary ossification. Report of two cases with unique findings.
Dendriform pulmonary ossification (DPO) is a rare condition characterized by branching bony spicules found in association with pulmonary fibrosis. The authors report two cases, the first of which occurred in a patient with acute myeloblastic leukemia and was associated with the unique finding of leukemic involvement of marrow spaces in the metaplastic bone. The second case showed DPO in combination with asbestosis, a heretofore unreported association.
