Background |
Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare primary cutaneous lymphoma of mature cytotoxic T cells. Initially, patients with SPTCL were treated with doxorubicin-based polychemotherapy.
Objective |
To analyze clinical, biologic, immunophenotypical, molecular, imaging, treatment, and outcome data reflecting the current state of knowledge.
Methods |
A retrospective multicenter study of 16 patients with SPTCL that was diagnosed between 1996 and 2016.
Results |
The female-to-male ratio was 1.7. The median age at diagnosis was 46.5 years. Patients presented with multiple nodular or plaque-like lesions preferentially affecting the legs and/or trunk. Histopathology typically showed a lobular panniculitis with individual adipocytes surrounded by atypical lymphocytes, usually with a CD3+, CD4–, CD8+, CD56–, TIA1 cytotoxic granule associated RNA binding protein 1–positive phenotype and high proliferation rate. SPTCL was associated with autoimmune diseases in 25% of patients, and with the development of hemophagocytic syndrome in 18% of patients. Oral steroids alone or in combination with low-dose methotrexate or cyclosporine A were the most common initial treatment, achieving a complete response in 85% of the treated patients. The median follow-up time was 14 months. The 5-year disease-specific survival rate was 85.7%.
Limitations |
This was a retrospective study.
Conclusions |
SPTCL has an excellent prognosis. Immunosuppressive agents can be considered for first-line treatment.
