title: Peripheral T-cell lymphoma involving subcutaneous tissue.
abstract: The peripheral T-cell lymphomas, presumably derived from various immunocompetent peripheral T-cell system components, form a heterogeneous group of non-Hodgkin's lymphomas. We describe two patients with peripheral T-cell lymphoma primarily involving subcutaneous tissue. They presented with multiple subcutaneous nodules. Skin biopsy specimens in both patients demonstrated a lobular subcutaneous infiltrate. The infiltrate consisted of small and medium-sized atypical lymphoid cells. Both patients had a protracted clinical course before they were diagnosed as having malignant lymphoma. We detected latent Epstein-Barr virus infection in the skin lesions of case 2. Latent Epstein-Barr virus infection might be related to the development of this variant of peripheral T-cell lymphoma.
