A case report and literature review: subcutaneous panniculitis-like T-cell lymphoma with liver failure as the main manifestation

Abstract

Background: Subcutaneous lipofuscinosis-like T-cell lymphoma (SPTCL) is a rare cutaneous lymphoma that often presents as recurrent subcutaneous nodules and may progress to hemophagocytic syndrome with fever and hepatic impairment in some patients. However, no cases of progression to hepatic failure have been reported. Here, we present a case of an adult diagnosed with fever and liver failure as the main manifestation, which was eventually confirmed as SPTCL by skin biopsy, but the patient eventually died due to disease progression.Case Description: This study retrospectively reports a rare case of SPTCL in a 34-year-old female patient who was admitted with scleral jaundice for 1 month and fever for 20 days. Examination revealed multiple small subcutaneous nodules on the skin of the chest and tibial surface and an enlarged liver and spleen. Laboratory tests revealed hepatic impairment, and common causes of liver failure (viral infection, fatty liver, immune liver damage, etc.) were excluded. We continued to refine the positron emission tomography-computed tomography (PET-CT) examination, which revealed multiple flocculent and nodular hyperdense shadows with increased metabolism in the subcutaneous fat interstices. And then, we performed a skin biopsy and the final pathological diagnosis was SPTCL, but the patient died 1 month after diagnosis due to poor treatment outcome because the disease progressed too rapidly. With this case report, we hope to improve clinicians' understanding of liver injury caused by SPTCL. A review of the literature revealed that this is the first case report in the literature of SPTCL leading to severe liver failure.Conclusions: For patients presenting with fever and liver injury, primary liver disease cannot simply be assumed, as this presentation may be a manifestation of some extra-hepatic diseases, including SPTCL. For this condition, early detection and early diagnosis may improve the prognosis of patients.
