Summary
This case study describes a rare presentation of peripheral T-cell lymphoma (PTL) in a 55-year-old female, characterized by significant liver and spleen enlargement and extensive hepatic granulomas. The atypical lymphoid cells likely triggered the unusual granulomatous reaction in the liver.
Area of Science:
- Oncology
- Hematology
- Pathology
Background:
- Peripheral T-cell lymphoma (PTL) is a diverse group of aggressive non-Hodgkin lymphomas.
- Hepatosplenomegaly and hepatic granulomas are uncommon presenting features of PTL.
Observation:
- A 55-year-old female presented with prolonged liver damage, triaditis, atypical lymphoid cells, and erythrophagocytosis.
- The patient developed marked hepatosplenomegaly and ultimately died of respiratory failure.
- Autopsy revealed widespread infiltration by T-cell marker-positive atypical lymphoid cells in multiple organs, including the liver, spleen, and lungs.
Findings:
- Histopathological examination confirmed peripheral T-cell lymphoma (PTL) with effacement of lymph node architecture.
- Numerous epithelioid granulomas were found admixed with atypical lymphoid cells within the hepatic parenchyma.
- This represents a unique presentation of PTL with hepatic granulomas as a predominant feature.
Implications:
- This case highlights the potential for PTL to manifest with unusual clinicopathological features.
- The findings suggest a possible role for atypical lymphoid cells in inducing granulomatous inflammation in the liver.
- Further research is needed to understand the mechanisms behind this rare presentation and its prognostic significance.
