FNAC has been attempted in the diagnosis of PPB in a number of cases, but has not been uniformly successful [see Bibliography, focus: FNAC]. The composition of the PPB tumor mass may be extremely heterogeneous and many portions may be virtually necrotic. In addition, as noted above, pleural fluid surrounding a PPB is usually non-diagnostic. Thus the role of FNAC in PPB diagnosis is not clear, in the opinion of the Registry.
