[The so-called sclerosing hemangioma of the lungs]

A 12-year old girl had a focal density in the lung found by checking CT. Structural features were those of the so called sclerosing hemangioma. Analysis of structure in various methods and of references supported authors' interpretation that lesion represented a late consequence of pecul a obliterative mainly venous process with prevailing plasmacytic feature. Characteristic segmental destructive venous lesion conused segmental obliterat on and hyalinization. Similarity of the lesion to intravascular fasciitis was discussed. Peripheral accumulation of pneumocytes around the lesion seemed to be secondary. To name it pneumocytoma would be unproper and a possibility of vascular tumorous character could not based on respectable analogies. A closer etiopathogenetic specification of the so called sclerosing hemangioma of the lung remains to be accomplished.
