Summary
Peripheral T-cell lymphoma can manifest in subcutaneous tissue, presenting as nodules. Epstein-Barr virus infection may play a role in this rare lymphoma variant.
Area of Science:
- Oncology
- Dermatology
- Virology
Background:
- Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of non-Hodgkin's lymphomas.
- PTCLs are presumed to originate from various components of the immunocompetent peripheral T-cell system.
Observation:
- Two patients presented with multiple subcutaneous nodules, indicating PTCL primarily involving subcutaneous tissue.
- Skin biopsies revealed lobular subcutaneous infiltrates composed of small and medium-sized atypical lymphoid cells.
Findings:
- Both patients experienced a prolonged clinical course before diagnosis of malignant lymphoma.
- Latent Epstein-Barr virus (EBV) infection was detected in the skin lesions of one patient.
Implications:
- This case series suggests a potential association between latent EBV infection and the development of subcutaneous PTCL.
- Further research is warranted to elucidate the role of EBV in this specific lymphoma subtype.
