Hepatocellular necrosis may be complicated in the clinical course of T-cell lymphoma. Herein are reported two cases of peripheral T-cell lymphoma associated with a rapid increase of serum transaminases in their final course. The final diagnoses were enteropathy-type T-cell lymphoma of the jejunum (patient 1) and hepatosplenic T-cell lymphoma (patient 2). The livers of both patients had non-zonal, well-demarcated coagulation necrosis (approximately 70% in patient 1 and 40% in patient 2) that was infiltrated by lymphoma cells bearing a cytolytic granule content (granzyme B). Hepatocytes in the necrotic areas in patient 2 showed immunoreactivity for human simplex virus type 1. Although the mechanism of the hepatocyte necrosis is unclear, it is suggested that the hepatocyte submassive necrosis may be related to an infection complicated in the final course of lymphoma or by certain direct effects of the tumor cells.
