An unusual nodular lesion of the liver: probable partial nodular transformation

An unusual nodular lesion of the liver is reported. The appearances closely resembled those described in cases referred to as partial nodular transformation, but there were several unusual features; these included areas with the appearances of cirrhosis, and significantly raised alkaline phosphatase and gamma glutamyl transpeptidase. Differentiation of this condition from other nodular lesions described in the literature is discussed. In the case reported here the Rose Waaler and Latex tests were also positive and this may be significant in view of certain types of nodular conditions described in some rheumatoid conditions. Although it is quite possible that these various lesions are related histogenetically, until more information becomes available, it is proposed that the lesion described here represents a variant of partial nodular transformation in which the changes in some areas have progressed to a stage of fibrosis.
