SPEC FRIAS, Ariel et al. Correlación clinicopatológica de las alteraciones hepáticas en las autopsias de pacientes con linfomas. Rev cubana med [online]. 1999, vol.38, n.2, pp. 123-133. ISSN 1561-302X.
Liver histopathological alterations were examined in 71 autopsies of patients with malignant lymphomas of whom 24 had Hodgkin´s disease (HD) and 47 non Hodgkin´s lymphomas. Lymphomatous infiltration was observed in 6 patients by initial liver biopsy (8 %) and in 44 patients by autopsies (62 %). This condition was higher in HD with 16 out of 24 patients (67 %) than in NHL with 28 out of 47 patients (60 %). Only 8 deceased (11 %) did not present any kind of alterations whereas 19 (27 %) had non-infiltrating histological alterations either isolated or combined. Frequency of fibrosis and necrosis was observed to be significantly higher in HD with 16 out of 24 patients (67 %, p = 0.0000) and 13 out of 24 patients (54 %), p = 0.0208) respectively, thus it was suggested that this disease is likely to have a pathogenic role in both processes. It was proved that congestion and steatosis had higher incidence on NHL with 28 out of 47 patients (60 %) and 24 out of 47 patients (49 %) respectively and that congestion was the most frequent non-specific alteration in all patients (53.5 % followed by necrosis (45 %). Neither correlation between histological findings from autopsies and disease status, visceromegaly, initial and therapeutical hepatic infiltration nor interaction between disease lenght and diagnosis, and histological alterations were found. It was confirmed that the increase of hepatic infiltration was linked to the course of the disease in patients with malignat lymphomas and that 85 % of these cases had some type of histopathological alteration either infiltrating or non-infiltrating in the liver at the time of their death.
