ADDRESSING THE INFILTRATIVE PATTERN: COMPLEX DIAGNOSIS

Abstract

Alterations in liver function tests are frequent, so the approach based on the predominant alteration and the patient's medical history is relevant. Carrying out a liver biopsy in cases of diagnostic doubt is imperative. The objective of this work is to describe a clinical case of an infiltrative pattern approach that culminated in the diagnosis of Hepatosplenic T-cell Lymphoma (HSCTL). Clinical case report. Presentation. Woman, 72 years old. History of a sister with cirrhosis. Consumption of alcohol and herbalists; arterial hypertension and Sjögren. He was admitted for persistent fatigue and jaundice. Laboratories with anemia, thrombocytopenia and kidney injury; Hepatic biochemistry with a predominantly cholestatic pattern at the expense of alkaline phosphatase and direct hyperbilirubinemia. Without acute liver failure. By imaging the liver, vessels and normal bile duct; splenomegaly; Negative hepatitis viral panel, positive ANAs and Anti-actin, negative antimitochondrials, normal immunoglobulins. HAI vs. DILI / HILI is suspected. Liver biopsy reports HSTCL-type lymphoproliferative process (Figure 1). It was supplemented with bone marrow aspirate and PET-CT. He started prednisone and cyclophosphamide. The systematic approach to altered liver biochemistry requires integrating personal and family risk factors for liver disease. The infiltrative pattern that resembles the cholestatic one represents a diagnostic challenge as it is little recognized. In this case, we report a rare neoplasm corresponding to 5% of peripheral T lymphomas; they usually develop in young adults and in the absence of lymphadenopathy. It also has an adverse prognosis due to refractoriness to chemotherapy. The HSTCL presented in this clinical case represents a complex and infrequent diagnosis. The symptoms and age group were atypical and the identification was possible through a systematic evaluation of the infiltrative pattern and differential diagnoses. The authors declare that there is no conflict of interest.
